BIOB34H3 Lecture Notes - Lecture 6: Extracellular Fluid, Blood Plasma, Osmoregulation
Document Summary
Interstitial fluid is outside of cell, bathes cell, outside blood vessel but outside other cells as well. Animals with closed circulatory system have three main types of fluid. Body solids are mostly proteins and lipids (5-40%) Osmoregulation regulation of various aspects of body fluids. Body fluid compartments closed circulatory system compartments intracellular fluids, blood plasma, interstitial fluid(lymph) 3 major fluids outside animal environment freshwater, marine water, Body fluid compartments regulation between blood plasma and other surrounding fluids is called endothelium also barrier between animal and external environment is called the integument. Barriers between fluids , plasma membrane between icf and ecf, boundary. Three major aspects of icf regulation blood and lymph terrestrial (air) Ionic composition of body fluids ion composition of ecf = seawater not equal to icf. Mos/mosm = milli osmolar, a osmole refers to only things in solution. Dominant ions in ecf sodium and chloride, supports idea life formed in.
