Document Summary

In the pulm veins, the left heart, and the systemic arteries. In the systemic veins, right heart, and pulm arteries. Blood vessels: delivery system of dynamic structures: arteries carry blood away from the heart, capillaries contact tissue cells; directly serve cellular needs, endothelium (with sparse basal lamina, veins carry blood toward the heart. Venous valves prevent backflow of blood (most abundant in veins of lower limbs) Venous sinuses: flattened veins with extremely thin walls: (e. g. , coronary sinus of the heart and dural sinuses of the brain) Vascular anastomoses - interconnections of blood vessels (can avoid path through capillaries: arterial anastomoses - provide alternate pathways (collateral channels) to given body region. Common @ joints, abdominal organs, brain, heart; none in retina, kidneys, spleen. Vascular shunts of capillaries: venous anastomoses are common. Arteriosclerosis = hardening of the arteries, less elastic (advancing age), increases resistance to blood flow, reducing normal circulation of blood making the heart work harder.
