16
Q

describe the role of the left atrium

A

receives newly oxygenated blood from the lungs

17
Q

describe the role of the right ventricle

A

receives deoxygenated blood from the right atrium
pumps it into the lungs for re-oxygenation/removal of CO2

18
Q

describe the role of the left ventricle

A

receives oxygenated blood from the left atrium
pumps blood into the aorta to different organs of the body

19
Q

what is the purpose of blood vessels?

A

carry blood throughout the body/cells
composed of smooth,, involuntary muscles

20
Q

describe the role of arteries

A

carry oxygenated blood AWAY from the heart
exception is pulmonary artery

21
Q

describe the role of capillaries

A

exchange nutrients, gases, waste between blood and tissue cells
connects arteries/veins

22
Q

describe the role of veins

A

carry deoxygenated blood back to the heart
exception is the pulmonary vein
