Document Summary

All vessels originate from aorta extending from lv. Pulmonary veins (2 right and 2 left) that drain into la. Lecture 9: the pulmonary circuit, oxygenated blood returns along small venules that join to form, systemic vessels, arterial system - moving out from the heart. Superior vena cava - from head, neck, chest, and upper limbs. Inferior vena cava - from all structures inferior to diaphragm. Arteries deep in skin, protected by bones and soft tissue. Veins - generally 2 sets, one deep and one superficial. Important in controlling body temp - venous blood flows superficially in hot weather to radiate heat and venous blood flows deep in cold weather to conserve heat. Changes in which veins the blood is perfusing through based on temperature: blood vessels of upper limb - arteries, aorta comes from lv, ascending aorta, aortic arch, descending aorta, 3 elastic arteries branch from aortic arch.
