Human anatomy and human /Urinary System Case Study

The brain and the glands of the endocrine system are the essential control centers involved in homeostasis, which regulate factors of temperature, heart rate, respiratory rate, blood pressure, water balance, blood sugar levels, and detoxification.
Different systems of the human body are involved in the factors essentially used ion homeostasis. An example is the urinary system. The urinary system has two major functions in the human consisting of the removal of harmful waste products from the human body, and controlling and balancing several substances found in blood, like water, acids and bases, ions, and salts.
The understanding of homeostasis is better explained by examining how a particular factor is regulated in the body during homeostasis. Let us take the example of blood pressure and the role of the urinary system in its regulation. The volume of blood can be increased and decreased by amount of water present in it, which is regulated by the hormone aldosterone. Aldosterone impacts on the rate of re-absorption of sodium ions in the kidney and through that the rate at which water is reabsorbed in the kidneys. The more the presence of aldosterone in the blood, the greater the re-absorption of water in the kidneys elevating blood pressure levels, and less the presence of aldosterone in the blood, less the water reabsorbed in the kidneys lowering blood pressure levels.

Strenuous exercise is one example of very high levels of extreme stress that the human body experiences. This becomes clear from the comparison between extreme fever and strenuous exercise. In the case of extremely high fever approaching levels that can cause death, the rate in increase of metabolism experienced is about one hundred percent above normal metabolic rates. In the case of strenuous exercise like running a marathon race, the increase in metabolism during the race, can go up to two thousand percent above normal metabolic rates. Strenuous exercise is thus an
