Physical characteristics that constitute health-related physical fitness include strength and endurance of skeletal muscles, joint flexibility, body composition , and cardiorespiratory endurance. There are two basic forms of exercise:

Knowledge Base

The Circulatory System

An increase in blood volume means your body can deliver more oxygen to your working muscles. Your body will also be able to better regulate your body temperature during exercise.

Cardiac output is the amount of blood your heart pumps out in one minute. It is regulated by the amount of blood your heart pumps out in one contraction, or stroke volume, and the number of times your heart beats in one minute, or your heart rate.

Cardiac output increases as a short-term and a long-term effect of regular aerobic exercise. Initially, cardiac output increases due to an increase in your heart rate.

Then, as your aerobic fitness improves, cardiac output increases due to an increase in stroke volume and a decrease in heart rate. Your systolic pressure is the pressure against your artery walls when your heart contracts. Diastolic pressure is the pressure against your artery walls when your heart relaxes.

When you first start to aerobic exercise, your blood pressure increases as your cardiovascular system works to deliver more oxygen and glucose to your working muscles. A long-term adaptation to aerobic exercise is a decrease in both your systolic and diastolic blood pressures during rest and during sub-maximal exercise.

The American College of Sports Medicine encourages regular aerobic exercise as a method of controlling and reducing high blood pressure due to its effects on lowering your blood pressure. In their absence the body and its activities would cease to be. Manifestly, the glands cannot pick their required elements from the blood unless their progenitors were previously taken in the foods eaten.??

The lymph vessels are fine tubes which accompany the blood vessels. They contain the lymph, a colorless, alkaline fluid, partly derived from the blood, partly from the juices of the partaken foods. To the lymph tubes belong the lymph glands, which are distributed over the whole system, having been given the task of extracting poisonous substances from the lymph.??

The lymph travels through the whole body like the blood, gathers in larger and larger vessels, and finally flows into the large veins near the heart; here it mixes with the blood, passes through the kidneys and lungs, and finally enters the heart as fresh new blood.??

The more toxic the poisons and mucus materials taken into the system, the more often the glands accumulate this bad waste from the lymph system and we have glandular swellings over various parts of the body.

An impure blood stream, constipation and a generally toxic body condition cause the glands to swell up and become painful. These may be on the neck, under the armpits, groin, etc. Formula for rebuilding glands using sarsaparilla, licorice, ginseng and astragulus as found in the Adrenal Newsletter. Cayce has a Formula that is similar and recommended to be used with the change of the seasons.?? What Can be Done for a Malfunctioning Thyroid?

From a question to Dr. Christopher in his Newsletter. Also, it is of special importance for the proper functioning of the reproductive system. The inter-relationship between reproductive functions and thyroid functions is very complex and not entirely? For instance, a slight enlargement of the thyroid gland is common at puberty, during pregnancy and menopause. Disorders of the thyroid gland are apparently caused by two conditions:?

We have had earaches in our family which resulted from congested lymph glands and colds. By inserting oil of Mullein into the ear, however, we were able to stop the irritation in the ear as well as in the accompanying glands. It contains essential hormones and enzymes necessary to keep the pituitary and adrenal glands functioning. There is a story we have told at many lectures and classes about the family that was incarcerated in a concentration camp during the Nazi occupation of Europe. This particular family found the strength to carry them through to the end of the war when they were released.

The key was an alfalfa plant growing in the corner of the compound, inside the fence. Each member of the family secretly permitted themselves a few leaves of the plant every day… allowing the alfalfa plant to replenish its leaves throughout the long months.

The family obtained the necessary nutriments from the plant. These nutriments were not provided by the inferior and scarce prison food. The family maintained their health while others around them dropped dead from malnutrition. There is a complex circulatory system in the body whose function can mean health or disease for each of us.

You may have heard the name of this system, but you might not know what it does or how it works. Most people have a fair understanding about the blood circulation system of the body, and many people have heard of the lymph nodes, but relatively few people know how significant the entire lymph system really is.

In fact, our bodies have twice the amount of lymph as blood and there are twice as many lymphatic vessels as there are blood vessels. In turn, the cells produce proteins and waste products and then the lymph absorbs these products and carries them away.

Any random bacteria that enter the body also find their way into this intercellular fluid. The fluid will return to the blood stream, but first, because it becomes contaminated with cell waste products, it must be cleaned. This is accomplished by filtering the lymph through the lymph nodes. At one time or another, everybody has felt congested nodes, especially in the neck, armpit, or groin. Toxins and poisons from something as simple as a cut finger can cause pain and swelling in the armpit nodes; an infected toe might cause the same type of feeling in the groin area nodes.

One place where we almost always notice lymph nodes is in the neck. When you have a sore throat or sinus congestion, you might become alarmed if you suddenly find a lump in your neck. Usually it is nothing more than a hard-working, efficient lymph node.

Although the lymph system has millions of vessels all over the body just like the blood system there is one big difference. It has no pump like the heart to keep it moving.

Instead lymph is moved by breathing, walking, intestinal activity, and muscle action. As muscles tighten, lymph vessels are squeezed and the lymph is pushed through the system and through the filtering nodes on its way back to the veins and the heart. Some other things that can be involved include recurrent low back ache, tennis elbow, sprained ankles, and even frequent nighttime urination. Obviously, for good health, we need to keep our lymph system moving, so exercise is essential to make our muscles contract, the lymph vessels squeeze, and the fluid move.

Something else you can do is find the reflex point that helps stimulate lymphatic drainage in the upper part of the body. It is located at the bottom part of the breast bone, or sternum. By vigorously rubbing this area for about two minutes, you can stimulate the lymph system.

We can also help lymph nodes drain by gently rubbing or milking them toward the heart. Working away from the heart will only irritate them, so be sure you work toward the heart. Use a lubricant like one of the medicated rubs and start under the jaw and milk down the throat on each side of the big muscle on both sides of the neck. Then, start at the base of the skull with your thumbs just behind the ears. Push under the skull, into the neck, with firm pressure slowly going toward the collar bone.

Continue to do this, and each time move the thumbs closer together toward the spinal column. Doing this alone has relieved headaches and neck tension. Another tip that will help the lymph system is to take both Vitamin C a natural source of vitamin A.

I recommend mg of vitamin C and IU of vitamin A daily. Now you know something about the lymph system and its workings. If you have any of the problems I mentioned, or if you begin to feel that familiar touch of sore throat, you can take action.

Lymphatic congestion or stagnation is a serious problem for many cancer patients. Undigested food, infectious material, dead cells, toxins, and other debris have to be carried off by the lymphatic system. Thickened and sluggish lymph results in swelling and discomfort. Very few people understand the humble working of the lymphatic system. Basically, the lymphatic system consists of one-way channels into which excess fluids, called lymph, are absorbed.

This fluid consists of waste materials and some white blood cells. It is not under pressure and only moves because of exercise or muscle contraction. Lymph moves towards the heart where it empties into veins. The two largest areas of lymph collection are just below the clavicles, areas that are often swollen or tender due to congestion in the lymphatic system.

The left side carries more fluid than the right, explaining why so many people experience worse swelling on the left side. Many patients suffered from congestion or conditions such as mastitis before developing cancer. The lymphatic system benefits from alkalization of the diet and improved digestion. As a general rule, there will be only minimal improvement in places such as the axilla or groin until the thoracic duct is freed of stagnation.

Angie used a machine to keep the lymph ducts open. She really worked my lymph hard and I felt it immediately. I had developed an ear infection traveling by plane and, within 1 hour, the infection was GONE! I was advised to drink a lot of water before and after the lymph treatment as water stimulates and drains the lymph.

The lymphatic system is unique because it consists of multiple and varied organs that work together to provide a supportive environment for cells. Specifically, the lymphatic system is composed of organs the spleen, thymus and tonsils , tissues nodes and an intricate network of highly permeable capillaries through which lymph a blend of proteins and fluids flows throughout the body.

Lymph contains white blood cells called lymphocytes. Like a team of well-trained maintenance workers, lymphocytes use antibodies to mop up interstitial fluid found between tissues and fluid leaked by blood vessels.

Highly specialized lymph nodes located throughout the body, including clusters in the neck, armpits and groin, act as filtering stations along the network of lymphatic vessels. While the cardiovascular system has the heart working on its behalf to pump blood throughout the body, the lymphatic system has no primary organ to circulate lymph, instead relying on the muscular contractions that accompany exercise and regular movement of the human body. The key is to engage the muscles, joints and ligaments in regular exercise, which keeps lymph flowing through the body so it can carry out its job.

The lymphatic system is distributed throughout the entire body, which means that all components of a healthy lifestyle help it function well. This, of course, includes a healthful diet. Rockwell told me that in healthy people the lymph system pretty much takes care of itself. Hydration is also important, as is doing all that you can to support proper digestion and enhance absorption of nutrients.

During a recent spa visit, I saw something called manual lymphatic drainage massage MLD offered on the menu, so I asked Dr. Rockson whether this is necessary or even helpful. The concept is that manual manipulation of nodes and skin encourages the fluid to circulate, helping the body dispose excess fluid and reduce edema swelling.

This can be helpful for people with lymphedema, but it is a specialized technique that requires medical knowledge, plus at least hours of specific training. Rockwell cautioned, it can be harmful if performed incorrectly, especially for a person with a lymphatic disease, including lymphedema, among others.

So, it turns out that the lymphatic system contributes much to our health, while requiring little in terms of special attention — consider it an extra benefit of good health habits that your lymph system functions better, too. Your website and this article on lymph is just what I needed today.

I live with MCS multiple chemical sensitivities. This article gives me reminders and new information to help move the toxins and toxics I accumulate. The self-massage descriptions are clear and tie so closely with the ear-aches and congestion and weakness that comes from exposures to chemicals and allergy producing triggers.

I love the bounce exercise idea! We live in a wee wheelie home and yet there is enough room for that if I just go do it! What a wonderful find for a Scorpio such as I during the Pluto retrograde. I thank Kathryn for the link to you. First generation space stations had crews who spoke a single language, while 2nd and 3rd generation stations have a crew from many cultures who speak many languages.

The ISS is unique because visitors are not classed automatically into 'host' or 'guest' categories as with previous stations and spacecraft, and may not suffer from feelings of isolation in the same way.

The sum of human experience has resulted in the accumulation of 58 solar years in space and a much better understanding of how the human body adapts. In the future, industrialisation of space and exploration of inner and outer planets will require humans to endure longer and longer periods in space. The majority of current data comes from missions of short duration and so some of the long-term physiological effects of living in space are still unknown. A round trip to Mars [47] with current technology is estimated to involve at least 18 months in transit alone.

Knowing how the human body reacts to such time periods in space is a vital part of the preparation for such journeys. On-board medical facilities need to be adequate for coping with any type of trauma or emergency as well as contain a huge variety of diagnostic and medical instruments in order to keep a crew healthy over a long period of time, as these will be the only facilities available on board a spacecraft for coping not only with trauma, but also with the adaptive responses of the human body in space.

At the moment only rigorously tested humans have experienced the conditions of space. If off-world colonization someday begins, many types of people will be exposed to these dangers, and the effects on the very young are completely unknown. On October 29, , John Glenn, one of the original Mercury 7, returned to space at the age of His space flight, which lasted 9 days, provided NASA with important information about the effects of space flight in older people.

Factors such as nutritional requirements and physical environments which have so far not been examined will become important. Overall, there is little data on the manifold effects of living in space, and this makes attempts toward mitigating the risks during a lengthy space habitation difficult. Test beds such as the ISS are currently being utilized to research some of these risks. The environment of space is still largely unknown, and there will likely be as-yet-unknown hazards.

Meanwhile, future technologies such as artificial gravity and more complex bioregenerative life support systems may someday be capable of mitigating some risks. From Wikipedia, the free encyclopedia. Health threat from cosmic rays.
