Production is caused by the need for oxygen and regulated by the kidneys.
Red Blood Cells
Carry oxygen to tissues by hemoglobin which attaches to RBC to keep tissues oxygenated. Also carries carbon dioxide away from tissues back to lungs.
A hematocrit test measures what proportion of blood is composed of RBC. Drawn blood is put through a centrifuge and spun so blood separates. Then the RBC are measured.
A hemoglobin test measures the hemoglobin levels of blood. Doctors draw blood to measure hemoglobin levels.
Anemia is a condition in which the blood does not have enough healthy red blood cells.
Iron Deficiency: Not enough hemoglobin in the RBC to carry oxygen.
Treatments: Iron supplements with Vitamin C or on an empty stomach, but not with anti-acids
Hemolytic: Occurs when RBC die quicker than the red bone marrow can replace them.
Treatments: Blood filtering, transfusion, removing of the spleen
Hemorrhagic: Anemia caused by loss of a lot of blood.
Treatments: Iron supplements or blood transfusion
Sickle Cell: Misshapen RBC caused by deformed hemoglobin that causes RBC to die prematurely.
Treatments: Blood transfusion, folic acid supplements, oxygen, and pain-relieving drugs or antibiotics like Hydroxurea.
Pernicious: Shortage of B-12 due to intestine infection or lacking diet
Treatmeants: Changes in diet, or supplement, or injections
White Blood Cells
Have larger nuclear than RBC, engulf and digest foreign materials, can draw cells to area by chemical release, and can move through other tissues and cells.
Involved in immune system to keep the bacteria levels in our body normal, and to keep us healthy.
60% of total WBC
In acute bacterial infections
2% of WBC
Breaks down antibody complex
.0004% of WBC
Found in inflammation
Contains Heparin- an anicoagulant

Cause blood to clot to stop bleeding.
Platelets gather at the bleeding site, then they stick to the edges; adhesion. Then they change shape and secret chemical messengers; activation. Lastly, they connect the bridges called aggregation. Then coagulation cascade forms a scab.
Heparin- Prevents clotting before or after surgery.
Aspirin- Treats pain and fever, also reduces risk of heart attack
Liquid portion of the blood that allows blood to flow. Keeps electrolytes in balance and prevents infection. Contains proteins, hormones, glucose, and electolytes.
