🗑
veins   any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.  
🗑
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 (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.  
🗑
oxygenated   supply, treat, charge, or enrich with oxygen.  
🗑
deoxygenated   remove oxygen from.  
🗑
agglutination   a reaction in which particles (as red blood cells or bacteria) 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.  
🗑
septum   a partition separating two chambers, such as that between the nostrils or the chambers of the heart.  
🗑
valves   s a device that opens or closes to let things through or to prevent passage.  
🗑
antibodies   a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.  
🗑
pulse   a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck.  
🗑
plasma   the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended.

🗑
white blood cells   One of the cells the body makes to help fight infections.  
🗑
red blood cells   any of the hemoglobin-containing cells that carry oxygen to the tissues and in mammals are typically biconcave disks which lack a nucleus and cellular organelles and are formed from nucleated cells of the red bone marrow.  
🗑
vaccine   a substance used to stimulate the production of antibodies and provide immunity against one or several diseases,  
🗑
immunity   the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.  
🗑
cancer   the disease caused by an uncontrolled division of abnormal cells in a part of the body.
