Document Summary
Mmm electric heater ( correctional mechanism ) physiological regulatory mechanisms. Satiety mechanisms : brain mechanism that causes cessation of hunger and thirst signals when the body has adequate nutrients from food or replenishment of water. * we measure bo system variables and correctional mechanisms in orderto accountfor slow nature of detectors in our system and rapid responses from correctional mechanisms water is absorbed ; f. Two semi independent fluid compartments exist within the body. Thirst : behavioral drive to seek and consume water. Intracellular ( interstitial) fluid : detects the fluid inside our cells and helps to maintain the balance ofsaltsefluids around our cells. Intewascular fluid : we can detect volume ofintewascularfluidto maintain functions of the heart and circulatory system isometric thirst monitored by osmoreceptors o o o. %abnjfke. im#s::::::::::::::: timing:p. ee#ti*naes:::::::::::::::::::: (o: my ocsstffetffesetnstitiveneuwm in tiring rate, which signals satiety as solute conc . of the interstitial fluid increases, firing rate, which signals thirst as www. ofinterstitalfluiddeoteases.
