Arteries bring oxygen to all the cells in our body. Capillaries exchange oxygen, nutrients, and wastes between the blood and the cells. Veins bring carbon dioxide back to the heart. There blood gets pumped over to the lungs to get rid of the carbon dioxide and pick up oxygen.

What's in Your Blood?

Plasma is the liquid portion of blood – a protein-salt solution in which red and white blood cells and platelets are suspended. Plasma, which is 92 percent water, constitutes 55 percent of blood volume. Plasma contains albumin (the chief protein constituent), fibrinogen (responsible, in part, for the clotting of blood) and globulins (including antibodies).

Platelets are parts of the blood that help the blood clot. They are smaller than red or white blood cells. from http://www.nlm.nih.gov/medlineplus/ency/article/003647.htm

White blood cells (leukocytes) are an important part of the body's defense against infectious organisms and foreign substances. To defend the body adequately, a sufficient number of WBCs must receive a message that an infectious organism or foreign substance has invaded the body, get to where they are needed, and then kill and digest the harmful organism or substance. from http://www.merckmanuals.com/home/blood_disorders/white_blood_cell_disorders/overview_of_white_blood_cell_disorders.html

Red blood cells are round with a flattish, indented center, like doughnuts without a hole. Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die. from http://www.urmc.rochester.edu/encyclopedia/content.aspx?ContentTypeID=160&ContentID=34
