Document Summary

4 types of connective tissues: epithelial- there to cover outside of body and line the organs, connective- cartilage, adipose tissue, and blood and bone, muscles- smooth, skeletal, and cardiac, and nervous. Exotherm- rely on environment to regulate their heat. 4 ways that temp is transferred: conduction- touch something heat is conducted to you, convection- circular heating motion causes more heating, radiation- heat being let our literally into the environment, evaporation- letting heat out through the loss of water. Cooling by evaporate: dog cooling with tongue out. Countercurrent exchange: blood flowing from your heart to your extremities; make sure the blood that comes back is next to warm blood from a warm blood vessel. Ingestion, digestion, absorption, elimination: sa node, fibers, av node to generate action potentials. Tripson is there to make it alkaline iga: mucuos and tears, igd; part of the b cell receptor. Ige; alleriges, igg; plasma cells, igm; secreted into the blood: cd4 t-cell, plasma cell, dendritic cells.
