Question 11

Aortic semi lunar valve

Answer 11

Keeps blood from moving back into the left ventricle

Question 12

Coronary arteries

Answer 12

Branch off the base of the aorta and in circles the heart and supplies blood to the heart muscle

Question 13

Cardiac veins

Answer 13

Takes the blood from the heart muscle back to the right atrium

Question 14

Heart attack

Answer 14

Occurs when blockage forms in the coronary arteries, depriving the heart muscle of much needed blood

Question 15

Artificial pacemaker

Answer 15

Damaged SA node causes heart to skip beats or beat irregularly

Question 16

Fibrillation

Answer 16

A rapid shuttering of the heart muscle and pumping pressure of blood is very low

Question 28

Systolic pressure

Answer 28

Top number, pressure exerted against the walls of the arteries at the peak of the pump

Question 29

Diastolic pressure

Answer 29

Bottom number, pressure on the walls of the arteries as the ventricle is resting
