Circulatory system

three independent systems that work together: cardiovascular, pulmonary and systemic

semipermable membrane that separates blood and the brain

The microcirculation is the circulation of the blood in the smallest blood vessels, the microvessels of the microvasculature present within organ tissues. The microvessels include terminal arterioles, metarterioles, capillaries, and venules. Arterioles carry oxygenated blood to the capillaries, and blood flows out of the capillaries through venules into veins.

large blood vessel in the arm

study of the circulatory system, specifically addressing the physiology of the heart ("cardio") and blood vessels ("vascular")
