The Basis of Physiological Regulation. Our bodies are made up of incredibly complex and delicate materials, and we are constantly subjected to all kinds of disturbances, yet we keep going for a lifetime. It is clear that conditions and processes in the body must be closely controlled and regulated, i.e., kept at appropriate values.. 2. Homeostasis is the ability of physiological systems to maintain conditions within the body in a relatively constant state of equilibrium. . Each cell in the body benefits from homeostasis, and in turn each cell contributes its share towards the maintenance of homeostasis. . understandings. U1. Insulin and Glucagon are secreted by alpha and beta cells in the pancreas to control blood glucose concentrations.. U2. Thyroxin is secreted by the thyroid gland to regulate the metabolic rate and help control body temperature.. . Stasis. = . standing. Greek for “. standing still. ”. Homeostasis is…. “the state of balance within our bodies”. Living organisms require a balance of certain variables within their bodies to stay alive. . ASSESSMENT.
