Cardio Syst - Blood
Terms in this set (19)
- Individuals with type AB blood - Do not have any a or b agglutinins in their plasma, they can theoretically receive blood from donors of all four blood types; there are no agglutinins to attack donated erythrocytes.
- Individuals with type O blood - have no A or B agglutinogens on their erythrocytes, they can theoritcally donate blood to recipients of all four blood types.
- Clumping of microorganisms or blood corpuscles; typically an antigen-antibody reaction - that is visible to the naked eye
- Isoantegens or Agglutinogens) are normal components of one person's RBC plasma membrane that can trigger damaging antigen-antibody response in other people
- Complement molecules poke holes in the donated RBC's causing them to burst and release hemoglobin into the plasma -- a reaction called Hemolysis.
Rh Blood Group
- Under normal circumstances, human plasma does not contain anti-Rh agglutinins. However, if an Rh- person receives Rh+ blood, the body starts to make anti-Rh agglutinins that will remain in the blood. If a second transfusion of Rh+ blood is given later, the previously formed anti-Rh agglutinins will react against the donated blood and a severe reaction may occur.)
- Is an overabundance of red blood cells
DISORDERS: HOMEOSTATIC IMBALANCES
- Is a decreased erythrocyte count or hemoglobin deficiency.
Anemia is a sign, not a diagnosis
- Arises from an inadequate diet, one that provides insufficient amount of iron, the necessary amino acids, or vitamin B12
- Is the insufficient production of erythrocytes resulting from an inability of the body to produce intrinsic (glycoprotein) factor. As a result, the person cannot absorb Vit. B12
- An excessive loss of erythrocytes through bleeding.
- Premature destruction of erythrocytes (red blood cells). (If erythrocytes cell membranes rupture prematurely, the cells remain as "ghosts", and their hemoglobin pour out into the plasma
- Destruction or inhibition of the red bone marrow.
Sickle-Cell Anemia (SCA)
- Abnormal kind of hemoglobin
- Abnormal increase in the number of erythrocytes
Infectious Mononucleosis (IM)
- A contagious disease that primarily affects lymphoid tissue. It is characterized by an elevated white blood cell count, with an abnormally high percentage of lymphocytes. Caused by Epstein-Barr virus (EBV).
Chronic fatigue syndrome
- Characterized by extreme fatigue for at least six months and the absence of known diseases that might produce similar symptoms. Among the symptoms are sore throat, headache, muscular aches, fever and chills, fatigue, joint pain, and neurological defects
- A malignant disease of blood forming tissues characterized by the uncontrolled productions of white blood cells that interferes with normal clotting and vital body activities
