Biology : Excretory System Quiz
Endurance athletes competing in grueling events like marathons must ensure they consume enough fluid to replace what they lose during the race. Unsourced material may be challenged and removed. This reduction in blood flow is necessary to maintain your blood pressure as blood vessels dilate in your working muscles. There are many causes of respiratory diseases, and many ways to treat such diseases. Exposure to secondhand smoke, also known as environmental tobacco smoke ETS , greatly increases the risk of lung cancer and heart disease in nonsmokers. These stones are most commonly made up of substances such as calcium, cystine, oxalate, and uric acid, as these are the substances that normally would dissolve within the urine.

After a certain point, the hypothalamus begins to boost the release of ADH from the pituitary gland to conserve water as much as possible. As ADH levels rise, the kidneys produce more concentrated urine, thus causing the level of sodium in the bloodstream to further drop. In extreme cases, an athlete may become dehydrated, or the decreased level of sodium in the blood can cause a condition called hyponatremia.

Sweating removes water and salts from your body together with a small amount of urea. As the level of sodium in your bloodstream drops, ADH secretion also falls, and your kidneys produce urine that is more dilute.

One of the ways your body excretes toxins is through sweat. When you exercise, you sweat more and you also need more water. Sweat is made up of some of the processes of respiration, such as dead cells, according to the Franklin Institute.

Aim to get 30 to 60 minutes of exercise three to five times per week. It has multiple functions, among them excreting toxins and metabolic by-products, maintaining the body's fluid and acid-base balance, regulating electrolyte levels and secreting several important hormones.

Exercise affects the urinary system in multiple important ways. When you exercise, blood flow to your kidneys is diminished due to an increase in the activity of the sympathetic nervous system, the "fight or flight" component of the nervous system. This reduction in blood flow is necessary to maintain your blood pressure as blood vessels dilate in your working muscles. Because of the decrease in blood flow, the amount of fluid filtered by your kidneys also is reduced during moderate to intense exercise, resulting in decreased urine production.

You can lose significant amounts of fluid as well as some sodium in your sweat as you exercise. To maintain fluid balance, the kidneys conserve sodium and reabsorb water, contributing to the reduction in urine production.

Although the amount of fluid conserved in this way during exercise is small compared to the amount you can sweat, the kidneys continue to conserve sodium for hours or even days after intense exercise to restore normal levels. A major hormone involved in maintaining fluid balance during exercise is antidiuretic hormone, or ADH, which causes the kidneys to conserve sodium. ADH also results in more concentrated urine.
