BIOL 2160 Chapter : Physio Chapter 13 Cardiovascular System
Document Summary
Functions of the circulatory system: transportation: ensure adequate blood flow through the capillaries to the various organs*** Hormonal: carry hormones to target tissues to produce their effects. Immune: leukocytes (antibodies and t cells), cytokines and complement fixation protect against pathogens. Pulmonary circuit: supplied, blood vessels from heart to lungs and lungs to heart. Systemic circuit: supplied, blood vessels from heart to systemic tissues and tissues to heart. Oxygenation of blood: pulmonary capillaries, blood entering lungs , blood leaving lungs , systemic capillaries, blood entering tissues , oxygen diffuses, blood leaving tissues = Path of blood flow through the cardiovascular system. Hypertrophic cardiomyopathy: genetic: 1:500 involves error in muscle proteins, leading cause of sudden death in young athletes. Atrioventricular valves = av valves: right av valve = tricuspid valve, left av valve = bicuspid valve = mitral valve, papillary muscles and chordae tendinae.
