Blood Hemo: Blood Hematology: The Study of Blood is living tissue that carries oxygen and nutrients to all parts of the body, and carries carbon dioxide and other waste products back to the lungs, kidneys and liver for disposal. It also fights against infection and helps heal wounds, so we can stay healthy.

Blood Components: 1. Plasma: Liquid part of blood

Blood Components: 2. Red Blood Cells: Erythrocytes Carries oxygen to all parts of the body

Blood Components: 3. White Blood Cells: Leukocytes Fights and kills germs that may enter your bloodstream

Blood Components: 4. Platelets: Thrombocytes – Helps stop bleeding by Forming “scabs” (coagulation)

ABO Blood Typing http: //www. youtube. com/watch? v=KXTF 7 Wehg. M 8 Bozeman Science Guy Intro to blood typing Before the 1900 s, it was thought that all blood was the same, a misunderstanding that led to frequently fatal transfusions of animal blood into humans and hazardous transfusions of blood between people. Human blood is not the same—people belong to different blood groups, depending upon the surface markers found on the red blood cell.

1. Antigens (Markers) Red blood cells are covered with surface markers, or antigens for identification.

Antigens (Markers) Blood type A Antigen A B B AB AB O None

Antibodies (Fighters) Used by the immune system to identify and neutralize foreign objects such as bacteria, viruses, or even incorrect blood.

Antibodies (Fighters) Blood type A Antibodies in bloodstream B B A AB None O Both

3. Rh Factors v Scientists study Rhesus monkeys to learn more about the human anatomy because there are certain similarities between the two species. While studying Rhesus monkeys, a certain blood protein was discovered. This protein is also present in the blood of some people. Other people, however, do not have the protein. The presence of the protein, or lack of it, is referred to as the Rh (for Rhesus) factor. A+ AB+ BAB+ ABO+ O-

Rh Factor v Another antigen (marker) found in blood v Rh+ Blood: You have the protein antigen v Rh- Blood: You don’t have the protein antigen Problem: When a fetus is Rh+ and the mother is Rh-, this can cause the mother’s immune system to attack the fetus. There are drugs that will suppress this reaction.

Blood Transfusions A blood transfusion is a procedure in which blood is given to a patient through an intravenous (IV) line in one of the blood vessels. Blood transfusions are done to replace blood lost during surgery or a serious injury. A transfusion also may be done if a person’s body can't make blood properly because of an illness. Universal Who can give you blood? Donor People with TYPE O blood are called Universal Donors, because they can give blood to any blood type. People with TYPE AB blood are called Universal Recipients, because they can receive any blood type. Rh + Can receive + or Rh - Can only receive - Universal Recipient

How common is your blood type? 46. 1% 38. 8% 11. 1% 3. 9%

Donors/Recipients “A” can give to “B” can give to “AB” can give to “O” can give to “A” can get from “B” can get from “AB” can get from “O” can get from A, AB B, AB AB A, B, AB, O A, O B, O A, B, AB, O O (Universal Donor) (Universal Recipient)

Blood: Genotypes The genetic makeup of blood Phenotype A B AB O Genotype AA, Ao BB, Bo AB oo What would be Homozygous? AA, BB, oo Heterozygous? Ao, Bo, AB
