Document Summary
Human physiology= study of natural bodily functions. Levels of organization in the body: molecular/ chemical, cellular, tissue, organ, body system, organism. Most common atoms: oxygen, hydrogen, carbon, nitrogen. 4 organic compounds: lipids, carbohydrates, proteins, nucleic acids. 4 types of cells: muscle, nervous, epithelial, connective. Use nutrients and oxygen to provide energy. Maintains balance of: temp, ph, blood pressure, oxygen, water balance. Ecf- extracellular fluid (includes interstitial fluid and plasma) Controls movement of molecules in and out. Helps join cells together to form tissues and organs. *if a molecule is hydrophobic it will be lipophilic. *if a molecule is hydrophilic it will be lyophobic. Cholesterol sits between phospholipid molecules and helps maintain membrane fluidity. Short sugar chains located on outer surface of membrane. Network of intracellular membranes that wind back and forth through cytoplasm. Function: forms new cell membrane and manufactures product for secretion. Some are attached to the er, some are free floating. Membranous sacs containing highly acidic degrading enzymes.
