How does blood flow through the cardiovascular system?

Answer 1

In the average person, (approxamately 82kg or 180lbs):

- there are approxamately 6 l or 10.5pts of blood

- the lungs can hold approxamately 6l or 10.5pts of air

- about 400 000km or 250 000mls of blood vessles, (I do not know the source of this bit of trivia) === === *Osmosis, the diffusion of water or another solvent through a selectively permeable membrane. This membrane is like a sieve, allowing solvent molecules, which are small, to pass through it, but preventing larger molecules dissolved in the solvent from passing through.

Answer 2

Deoxygenated blood is carried by veins from the body to the right side of the heart. The right ventricle pumps the deoxygenated blood to the lungs via the pulmonary arteries. Oxygen diffuses into the blood in the lungs, and carbon dioxide diffuses out of the blood into the lungs. After oxygenation, blood is carried to the left side of the heart via the pulmonary veins. The left ventricle pumps the oxygenated blood through the aorta, the largest artery in the body, to the rest of the body. The aorta branches into smaller arteries, which branch into arterioles, which branch into capillaries. At the capillaries, oxgen, nutrients, and certain hormones are delivered to the body cells, and the body cells deliver carbon dioxide, wastes, and certain hormones to the blood. The capillaries then form into venules, then veins, which then deliver the deoxygenated blood to the right side of the heart via the vena cavae, the largest veins in the body. This cycle occurs every second of every day of your life.
