A blood vessel that carries oxygen-poor blood from the heart to the lungs:

• pulmonary vein

• aorta

• pulmonary artery

• superior vena cava

Contraction phase of the heartbeat:

• diastole

• pacemaker

• tachycardia

• systole

The valve that is located between the upper and lower chambers of the heart:

• lower valve

• mitral valve

• aortic valve

• pulmonary valve

What is the sac like membrane that surrounds the heart:

• endocardium

• bundle of his

• pericardium

• ventricle

The sensitive tissue in the right atrium that begins the heartbeat:

• tricuspid valve

• atrioventricular node

• sinoatrial node

• bundle of his

Blood vessels branching from the aorta to carry oxygen rich blood to the heart muscle:

• capillaries

• renal veins

• coronary arteries

• femoral veins

Instrument used to measure the blood pressure:

• electrocardiogram

• sphygmomanometer

• cardiac catherization

• stress test

A large vein that returns blood to the right atrium of the heart:

• superior vena cava

• pulmonary vein

• pulmonary artery

• aorta

The muscular middle layer of the heart is:

• myocardium

• endocardium

• pericardium

• endothelium

The largest artery in the body is:

• aorta

• arteriole

• inferior vena cava
