Document Summary
Influence almost every cell, organ, and function of the body: regulates mood, growth and development, tissue function, and metabolism, sexual function and reproductive processes. In charge of body processes that happen slowly (ie. cell growth: foundation = hormones + glands, hormones = body"s chemical messengers. Characteristics of hormones released/synthesized by endocrine system: 1. Rates and rhythms of secretion: diurnal pattern, pulsatile and cyclic pattern, patterns that depend on levels of circulating substrates (eg. calcium, sodium, potassium, hormones, 2. Hormones operate within feedback systems (positive or negative) to maintain an optimal internal environment: 3. Hormones affect only cells with appropriate receptors and then act on those cells to initiate specific cell functions or activities: 4. Kidneys excrete hormones, whereas the liver metabolizes hormones inactivating them and rendering the hormone more water soluble for renal excretion. Hormones: chemical messengers that transfer information and instructions from one set of cells to another.
