1

Clumping of (foreign) cells; induced by cross-linking of antigen-antibody complexes.

Agglutination

2

Reduced oxygen-carrying ability of blood resulting from too few erythrocytes or abnormal hemoglobin.

Anemia

3

Major systemic artery; arises from the left ventricle of the heart.

Aorta

4

A minute artery.

Arteriole

5

Blood vessels that conduct blood away from the heart and into the circulation.

Artery

6

Specialized mass of conducting cells located at the atrioventricular junction in the heart.

Atrioventricular node (AV Node)

7

Valve that prevents backflow into the atrium when the connected ventricle is contracting.

Atrioventricular valve (AV Valve)

8

The two superior receiving chambers of the heart.

Atria

9

White blood cell whose granules stain purplish-black and nucleus purple with basic dye.

Basophil

10

The smallest of the blood vessels and the sites of exchange between the blood and tissue cells.

Capillary

11

The functional blood supply of the heart; shortest circulation in the body.

Coronary circulation

12

Period of the cardiac cycle when either the ventricles or the atria are relaxing.

Diastole

13

Diagnostic test to determine relative proportion of individual leukocyte types.

Differential white cell count

14

Obstruction of a blood vessel by an embolus (blood clot, fatty mass, bubble of air, or other debris) floating in the blood.

Embolism

15

Endothelial membrane that lines the interior of the heart.

Endocardium

16

Red blood cells.

Erythrocytes

17

Process of erythrocyte formation.

Erythropoiesis

18

Pierced with one or more small openings.

Fenestrated

19

A soluble blood protein that is converted to insoluble fibrin during blood clotting.

Fibrinogen

20

Circulation in which the hepatic portal vein carries dissolved nutrients to the liver tissues for processing.

Hepatic Portal system

21

Vein that returns blood from body areas below the diaphragm.

Inferior vena cava

22

White blood cells; formed elements involved in body protection that take part in inflammatory and immune responses.

Leukocyte

23

Abnormally low white blood cell count.

Leukopenia

24

Layer of the heart wall composed of cardiac muscle.

Myocardium

25

Valves that prevent blood return to the ventricles after contraction; aortic and pulmonary valves.

Semilunar valves

26

Specialized myocardial cells in the wall of the right atrium; pacemaker of the heart.

Sinoatrial (SA) node

27

Vein that returns blood from body regions superior to the diaphragm.

Superior vena cava

28

System of blood vessels that serves gas exchange in the body tissues.

Systemic circuit

29

The right atrioventricular valve.

Tricuspid valve
