MEDICAL PHYSIOLOGY

Detailed explanation-1: -Hormones are responsible for key homeostatic processes including control of blood glucose levels and control of blood pressure. Homeostasis is the regulation of the internal conditions within cells and whole organisms such as temperature, water, and sugar levels.

Detailed explanation-2: -Variables such as body temperature, pH, sodium level, potassium level, calcium level, and blood sugar level have to be kept within the homeostatic range. The homeostatic range is defined as the allowable upper and lower limits for a particular variable.

Detailed explanation-3: -Thermoregulation is coordinated by the nervous system (Figure 11.2). The processes of temperature control are centered in the hypothalamus of the advanced animal brain. The hypothalamus maintains the set point for body temperature through reflexes that cause vasodilation or vasoconstriction and shivering or sweating.

Detailed explanation-4: -Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis (“steady state”). These changes might be in the level of glucose or calcium in blood or in external temperatures. Homeostasis means to maintain dynamic equilibrium in the body.
