ANA300Y1 Lecture Notes - Lecture 16: Pulmonary Artery, Pulmonary Valve, Pulmonary Circulation
Document Summary
Diffusion along in larger animals can"t provide cells with things as quickly as it needs for transport cardiovascular system allows us to move things faster using bulk flow efficiently transport materials. Regulation of cardiovascular system involves the nervous system, endocrine and renal system. Cardiovascular system functions transport of substances: oxygen and nutrients to cells, wastes from cells to liver and kidneys hormones, immune cells, and clotting proteins to specific target cells. Generally arteries carry oxygenated blood and veins carry deoxygenated blood. Coronary arteries arise from aorta and how the heart feeds itself. Heart is divided into the left and right heart left and right heart is further divided into the upper chambers called the atria and lower chambers called the ventricles thus 4 chambered system: Ventricular muscle left ventricular muscles is much thicker than the right ventricular muscle. Enables the left heart to develop greater pressure to supply blood to body (systemic circuit)
