Q

Pericardium

A

17
Q

Atria

A

Receiving chambers of the heart

18
Q

Ventricles

A

Pumping chambers

19
Q

Tricuspid Valve

A

Controls the opening between the right atrium and the right ventricle

20
Q

Pulmonary Valve

A

Prevents blood that has been ejected into the pulmonary artery from returning to the right ventricle

21
Q

Mitral Valve

A

Blood flows through this atrioventricular valve to the left ventricle and cannot go back up into the left atrium

22
Q

Aortic Valve

A

Blood leaves the left ventricle through this valve and cannot return to the left ventricle

23
Q

Blood Pressure
