Lub-dub, lub-dub

• 4 valves in the heart

– flaps of connective tissue

– leaking valve causes hissing sound

– blood squirts backward through valve

veins

aorta carotid = to head

to brain & left arm to right arm

coronary

arteries

to body

Coronary artery bypass

bypass surgery

Electrical signals

allows atria to empty completely before ventricles contract

stimulates ventricles

to contract from bottom to top, driving blood into arteries

• heart pumping controlled by electrical impulses

• signal also transmitted to skin = EKG
