1

Aorta

The major artery from the heart

2

Arteriole

The smallest branch of an artery, which at its distal end leads into a capillary

3

Artery

Blood vessel that carries blood away from the heart

4

Atria

The two upper chambers of the heart. PL of atrium

5

Automaticity

The ability of cells within the cardiac conduction system to generate a cardiac impulse on their own

6

Blood pressure

The force exerted by the blood on the interior walls of the blood vessel

7

Capillary

Tiny blood vessel that connects and arterial to a venule

8

Cardiac compromise

Reduced hurt function caused by any of a variety of conditions, diseases, or injuries affecting the heart

9

Cardiac conduction system

The specialized contractile and conductive tissue of the heart that generates electrical impulses and causes the heart to beat. Also called the coronary conduction system.

10

Circulatory system

System composed of the heart and blood vessels that brings oxygen and nutrients to and takes waste away from body cells. Also called the cardiovascular system

11

Coronary arteries

Blood vessels that supply the heart with blood

12

Heart

The muscular organ that contracts to force blood into circulation through the body

13

Nitroglycerin

Medication that dilates the blood vessels, increasing blood flow through the common arteries and decreasing the workload of the heart, often prescribed for patients with a long history of chest pain.

14

Perfusion

The delivery of oxygen and other nutrients to the cells of all organ systems, which results from the constant adequate circulation of blood through the capillaries

15

Pulmonary artery

Artery that carries oxygenated blood from the right ventricle of the heart to the lungs

16

Pulmonary vein

Vein that carries oxygenated blood from the lungs to the left atrium of the heart

17

Vein

Vessel that carries blood toward the heart

18

Venae Cavae

The principal veins that carry deoxygenated blood to the heart. Plural of vena cava. The superior vena cava carries blood from the upper body, the inferior vena cava carries blood from the lower body.

19

Ventricles

The two lower chambers of the heart

20

Venule

The smallest branch of a vein
