What is physiological homeostasis?

Physiological homeostasis is the state of internal stability achieved through specific mechanisms and physiological cycles in the living system. French scientist Claude Bernard was among the first to articulate and expressed the importance of physiological homeostasis at the age of 60. He assumed that the living organism does not only exist and owes its survival only to the external environment, but to the inner atmosphere, which is maintained through the circulation of elements working as a whole. The function of liver, kidney and brain is one of the most important elements of human physiological homeostasis. If a healthy condition is not maintained, the body may suffer and sometimes succumb to diseases such as diabetes and DNA, due to homeostatic imbalance.

Thermoregulation, which is deeply important for the survival of man, is an example of the Physioloogical Homeostasis mechanism. Most of the body heat is generated in the deep organs of the body, mostthe liver. If the body begins to heat up or cool quickly, its homeostatic mechanism enters. The first step in thermoregulation performs the skin because vasodialales and sweating if the body begins to get heat as during exercise, forcing erection of body hair when the body loses heat to form a layer of insulation. The circulation system also contributes to thermoregulation by limiting capillaries of nearby skin under cold conditions to minimize heat loss, and subsequently expand the capillaries in hot conditions to maximize excess heat diffusion.

Blood composition must achieve a state of physiological homeostasis to keep the human system healthy. Two hormones, glucagon and insulin, both relaxed from the pancreas, help regulate the level of blood sugar. After a meal, when the Klokukr begins to rise dramatically, the insulin is released to reduce the sugar level. Conversely, when blood sugar begins to dive, glucagon relaxes to raise blood sugar levels between meals. Homeostatic imbalance is observed in the form of diabetes if the pancreas cannot produce or release the corresponding amount of both hormones. Blood solut levels are also regulated by the kidneys when they filter blood and determine the speed of reabsorption of soluts such as glucose, amino acids and electrolytes.

Another condition for physiological homeostasis is to regulate the concentration of body hydrogen (PH). The kidneys monitor the pH level in blood plasma because it is filtered through the renal system. The kidney feedback triggers the release of buffer substances such as bicarbonate and ammonia to ensure that the level remains between 7.35 and 7.45 on the ph scale.
