PHSI 208 Final: Comprehensive Final Exam Study Guide
Document Summary
Control systems and homeostasis: to maintain homeostasis, the body monitors certain key functions, regulated variables are kept within a normal range by control mechanisms which can be local or reflex. Biological membranes: separate one compartment from another, consist of a bilayer of phospholipids with protein molecule inserted. The cell membrane: composed of lipid, protein and a small amount of carbs, three types of lipids found in the cell membrane. Immunologic molecule: structural molecule, transport molecule, hormone, enzyme, cell-cell recognition, receptor, glycolipid, serve as recognition sites for cell-cell interactions. Integral proteins (transmembrane and lipid anchored) wide variety of functions: peripheral proteins attached to integral proteins to participate in cell signaling and attachment of cytoskeleton, carbohydrates, glycoproteins and glycolipids wide variety of functions. Membrane dynamics: body fluid compartments, cells intracellular fluid (icf, 2/3 of the total body water volume, extracellular fluid (ecf) 1/3 of the total body water volume.
