Detailed explanation-1: -Another example of negative feedback is the regulation of the blood calcium level. The parathyroid glands secrete parathyroid hormone, which regulates the level of calcium in the blood. If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone.
Detailed explanation-2: -When exposed to hot conditions, sweating is one of the primary methods your body uses to control its temperature. Sweat, as it evaporates, helps cool the skin. Blood vessels feeding the skin also dilate, which allows warm blood to flow to the skin surface. This helps remove heat from the body core.
Detailed explanation-3: -Most positive feedback mechanisms are harmful and in some cases resulting in death. For example, if a person breathes air that has very high carbon dioxide content. The amount of oxygen in blood decreases while the concentration of carbon-dioxide in blood increases.
Detailed explanation-4: -If the body temperature increases too much, the body has protective mechanisms that reduce the temperature to stop enzymes from denaturing: Blood vessels dilate – the blood vessels near the skin tend to dilate. This is known as vasodilation.
