| Capillaries | any of the fine branching blood vessels that form a network between the arterioles and venules. |
| Arteries | any of the muscular-walled tubes forming part of the circulation system by which blood is conveyed from the heart to all parts of the body. |
| Oxygenated | supply, treat, charge, or enrich with oxygen. |
| Deoxygenated | remove oxygen from. |
| agglutionation | a reaction in which particles suspended in a liquid collect into clumps and which occurs especially as a serological response to a specific antibody. |
| ventricles | a hollow part or cavity in an organ, in particular. |
| atria | each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein. |

| cancer | the disease caused by an uncontrolled division of abnormal cells in a part of the body. |
