A 35 minute essay on Homeostasis in living organisms

Homeostasis is the control of the internal environment of an organism, allowing greater independence from external conditions. This control is usually achieved by a system of negative feedback. Regulation of temperature and blood glucose levels in humans are two good examples of homeostasis. In the case of body temperature, any deviation from the optimum temperature of 37º C is detected by the hypothalamic heat and cold receptors located in the hypothalamus and the peripheral cold receptors …showed first 75 words of 631 total…

In the event of a decrease in the solute concentration of the blood, the ADH release is reduced, having the opposite effect. Homeostasis is a vital mechanism in humans and other organisms, enabling the survival of some species in very harsh conditions, such as deserts, extreme cold, or bacteria living in hot springs or extremes of pH. The failure of any homeostatic mechanism would usually result in death.
