Document Summary
Veins from the spleen, stomach, pancreas, gallbladder, and intestines send their blood to the liver by way of the hepatic portal vein. In the liver, the venous blood mingles with arterial blood in the sinusoids and is eventually drained from the liver by hepatic veins that join the inferior vena cava. Exercise thickens the myocardium and increases supply of blood vessels in skeletal muscle tissue. Atherosclerosis is blockage or weakening of critical arteries, heart valves and myocardial tissue degenerate, reducing pumping efficiency. Ra > rv > pulmonary arteries > lungs (pumlonary circuit)> pulmonary veins > la > lv > aorta, systemic arteries > body (systemic circuit) > systemic veins > vena cava. Tricuspid valve between right atrium and right ventricle. Bicuspid valve (mitral valve) between left atrium and left ventricle. Mitral and tricuspid valves are the av valves (between atrium and ventricles) Pulmonary vein contains oxygen, most veins do not contain oxygenated blood.
