maintain blood pressure even when the heart relaxes ; carries out blood
what are the functions of a vein - CORRECT ANSWER -returns deoxygenated blood back into heart
what the functions of the arteriole - CORRECT ANSWER -transports blood from arteries to capillaries
what are the functions of the venue - CORRECT ANSWER -
a very small blood vessel, always allows blood to return from capillary beds to drain into larger blood v
essels.
what are the functions of the capillary - CORRECT ANSWER -
the smallest of blood vessels, they distribute oxygenated blood from arteries to the tissues of the body
and to feed deoxygenates blood from the tissues back into the veins.

where would you find the sulk of the heart? - CORRECT ANSWER -- there are 2 -> l and r ventricles
Where would you find the intertribal septum? - CORRECT ANSWER -the wall between ATRIA
where would you find the inter ventricular septum ? - CORRECT ANSWER -
the thicker wall between VENTRICLES
Where would you find the bicuspid valve? - CORRECT ANSWER -In the left ATRIUM
Where would you find the tricuspid valve? - CORRECT ANSWER -in the right ATRIUM
where will you find the pulmonary semilunar valve? - CORRECT ANSWER -in right VENTRICLE
