Document Summary
Removes co2 & other metabolic waste products. Supports thermoregulation & controls the balance of body fluids. Skin turns red when it"s hot because increased bf to skin (mechanism for heat- loss). Maintains acid-base balance controls body ph. About the size of a fist & located in the middle of the thoracic cavity. Enclosed in the pericardium membranous sac. Chordae tendinae hold values together ensures 1-way flow. Left & right rides of the heart pump the same amount of blood prevents blood back-up. Lined by endocardium (interiorly) and pericardium (exteriorly). Thickest myocardium because it"s the most powerful pump: must overcome gravity to pump blood to the whole body. Exercise: hypertrophy allows more blood-supply to ensure proper muscle function by increasing the size of the chamber, # of blood vessels that supply it. Diseases (hypertension; valvular heart disease): hypertrophy causes problematic need for more blood-supply to ensure proper muscle function. Characteristics of myocardium that are different from skeletal muscle.
