Tracing The Flow of Blood Through The Body

When a heart contracts and forces blood into the blood vessels there is a certain path that the blood flows through the body. The blood moves through pulmonary circulation and then continues through systemic circulation.

Identification of Types of Blood Vessels

Arteries - Transport the oxygenated blood away from the left side of the heart. They become thinner as they spread out from the main arteries. The small branches are called Arterioles, the largest artery in the body connected directly to the heart is the Aorta.

Veins - Transport used blood from all over the body back to the heart and lungs for re -oxygenation. Veins look blue through your skin they are blue because they carry blood that is full of waste products and are low in oxygen. Veins also have valves like the valves in the heart they are there to prevent the back flow of blood. The blood must flow in one direction only.

Capillaries - Are minute blood vessels that join onto the Arterioles. They are one cell thick and are exchange points where the nutrients oxygen and glycogen cross into the tissue cells from the Arterioles. Waste products from the tissues cross back into the bloodstream in the capillaries then into the small veins (venules).

Describing Blood Cell Formation

Blood cell formation also called Hematopoiesis or Hemopeoiesis continuous process by which the cellular constituents of blood are replenished as needed. Blood cells are divided into 3 groups: the red blood cells, the white blood cells, and the blood platelets. The white blood cells are subdivided into three broad groups; Granulocytes, Lymphocytes, and Monocytes.

Distinguish Among Human Blood Groups

Blood Type A - Has only "A" antigen on red cells and "B" antibody in the plasma.

Blood Type B - Has only "B" antigen on red cells and "A" antibody in the plasma.

Blood Type AB - Has both "A" and "B" antigens on red cells but neither "A" nor "B" antibody in the plasma.

Blood Type O - Has neither "A" nor "B" antigens on red cells but both "A" and "B" antibody are in the plasma.

Describing Common Cardiovascular Diseases and Disordes

Myocardial Infraction - A blockage of blood flow to the heart muscle which is a heart attack.

Stroke - Damage to the brain from interruption of its blood supply.

High Blood Pressure - A condition of which the force of the blood against the artery walls are to high.

Arrhythmia - Improper beating of the heart, whether irregular, too fast, or too slow.
