__**The Blood**__
 * a blood type is classified by the antigens that are present or not present on the blood celll
 * the antigens have proteins and carbohydrates depending on the blood group
 * when the red blood cells surface the antigens they start to stem from one allele to the other forming stems that collectively form a blood group
 * Blood type is inherited from the mother and the father

__**Antigens**__
 * A molecule that stimulates the immunes response
 * Are usually proteins and are on the surface of blood cells

__**Antibodies**__
 * Are proteins found in the blood and are used by the immune system to identify objects that are unknown to the body (virus and bacteria)
 * they are produced by a white blood cell called a B cell[[image:file:255px-Antibody.svg.png]][[image:255px-Antibody.svg.png]]

__**The different types of blood**__
 * Type A blood
 * people with this blood type have A antigens on the surface of their red blood cells and contain B-antibodies
 * They can receive blood from A or O blood and donate blood to type A and AB blood
 * Type B blood
 * People with this blood type have B antigens on the surface of their red blood cells and contain A- antibodies
 * They can receive blood from B or O blood and donate blood to type B or AB
 * Type AB blood
 * People with this blood type have both A and B antigens on the surface of their red blood cells and contain no antibodies against A or B blood because they have A and B antigens
 * They can receive blood from any blood group but can only donate to another person with AB blood
 * Type O blood (universal blood donor)
 * People with this blood type do not have any antigens on the surface of their red blood cells and contain both A and B antibodies against A and B antigens
 * They can only receive blood from people with type O blood but can give blood to every blood group
 * __Rh__**
 * Rh is a type of antigen that can or cannot be present in the blood
 * When a person is tested for their blood type they are also tested for Rh as well
 * Once determined a negative or a positive is used after the blood type (ABO)
 * example: A positive or AB negative

__**Common Blood Types**__ In the United States the most common blood type is O postive (38%) Blood type A positive is the next common (34%) The lowest is AB negative (1%)
