1. Blood compatibility

2. Blood types
A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells

3. Blood types
There are four major blood types: A, B,
AB,
and O

4. Antigens
There are two antigens, A and B. If you have the A antigen on the RBC, then you have type A blood.
When B antigen is present, you have type B blood.
antigens may be proteins, carbohydrates, glycoproteins or glycolipids depending on the blood group system 4

5. Antigens
When both A and B antigens are present, you have type AB blood.
When neither are present, you have type O blood.

6. Rh blood group
In addition to the ABO blood group system, there is an Rh blood group system
The D antigen is the most common Rh antigen. If the D antigen is present, then that blood is Rh+. If the D antigen is missing, then the blood is Rh-.

7. Blood compatibility Not all blood types are compatible
There are universal donors and universal recipients

8. In terms of RBC
O- (universal donor blood)
AB + (universal recipient)
In terms of plasma
Plasma extracted from type AB blood can be
transfused to individuals of any blood group,
but type O plasma can be used only by type
O recipients

10. The Circulatory System
Moves nutrients, gases, and wastes to and from cells
Helps fight diseases
Stabilizes body temperature and pH
Humans have a closed system (blood never leaves the network of arteries, veins, and capillaries
Stabilizes body temperature and pH to maintain homeostasis- stable internal state

11. The Circulatory System
The circulatory system consists of :
The heart
Blood vessels
Blood

12. The Circulatory System
Includes pulmonary circulation- oxygen depleted blood carried away from heart to lungs and returns oxygenated blood to heart
Systemic circulation- carries oxygenated blood away from heart to rest of body and returns deoxygenated blood

13. The Arteries, Veins, and Heart
Arteries take blood away from the heart
Veins bring blood back to the heart
The heart has four chambers- left atrium, left ventricle, right atrium, right ventricle
