Q

describe the pathway of oxgenated blood through the heart

A

comes into the pulmonary veins from the lungs, moves through the mitral valve to the left ventricle, then moves through the aortic valve where the aorta disperses it to the upper an dlower body

Q

describe the pathway of deoxygenated blood through the heart

A

comes into the superior/inferior venacavas, then moves through the right atrium into the tricuspid valve. Then it comes from the right ventricle through the pulmonary valve and into the pulmonary artery

Q

what does the av node to with the electrical impulse

A

it recieves, then delays, the impulse. This allows the atria to empty the blood into the ventricles
