Document Summary

Albumin is the major protein in our blood. Homeostatic control systems: most systems have both extrinsic and intrinsic control, example: the heart. Anp is like a hormone (thus, the heart can sort of be considered a gland) Normal resting state of the heart is ~60-80 beats per minute: most feedback is negative, feedforward regulation. Present in all systems: positive feedback always amplifies the initial change, neurological diseases prevent these mechanisms from working properly. In the picture: red is sensory, blue is motor. Glucose homeostasis: we have body cycles that affect our glycemia (for example) Insulin is the only hypoglycemic hormone brings glucose to tissues: hyperglycemic hormones increase blood glucose. Growth hormone aka gh (from the adrenal hypothesis) These hormones are high when we wake up. After a meal, they decrease and insulin levels increase: the body learns feedforward regulation, there"s an enzyme in muscles that keeps glucose from leaving once it gets inside.
