Why is excretion important for homeostasis

Water is lost from the body as:. Sweat glands in the skin produce sweat. Water, ions and urea are lost from the skin as they are contained in sweat.

Water leaves the body via the lungs when we exhale as well as excess carbon dioxide. We cannot control the level of water, ion or urea loss by the lungs or skin. For example, in a hot climate, your body sweats to help keep you cool.

In the same way, when we breathe out we lose water vapour, and we cannot alter the amount we lose. What are the units used for the ideal gas law? How does Charle's law relate to breathing? What is the ideal gas law constant? How do you calculate the ideal gas law constant?

How do you find density in the ideal gas law? Does ideal gas law apply to liquids? Impact of this question views around the world. Although the urinary system has a major role in excretion, other organs contribute to the excretory function. The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water. The skin is another excretory organ that rids the body of wastes through the sweat glands.

The liver and intestines excrete bile pigments that result from the destruction of hemoglobin.
