Document Summary
Introduction to cardiovascular system, arrangement of cv system, pulmonary circuit. Deals with bf between heart and lungs only, not the whole body: systemic circuit. Provides bf to all other tissues of the body. Needs higher pressure to be able to carry blood throughout the body: microcirculation vs. macrocirculation, macrocirculation. Provides bf to and from tissues: microcirculation. Refers to vessels that are encased or enclosed in the systems. Regulates exchange of oxygen, carbon dioxide, and nutrients: diagram to right: Illustrates a person standing upright and facing you. Arterioles dilate and constrict very easily as seen with the stop clog in the diagram. Left ventricle has much thicker muscles, so it can develop enough pressure to pump blood through the whole body. Capillaries: thin wall, exchange vessels, very small vessels lined up side by side. Note the size of the veins vs. arteries: veins can hold a whole lot more blood, and are bigger, cv adjustments to exercise in the diagram.
