Study Notes
The Cardiovascular System
- The cardiovascular system moves blood throughout the body through a network of blood vessels.
- Blood acts as a medium to deliver nutrients and oxygen to organs and tissues, and remove metabolic waste.
- Blood also transports immune elements and aids in clotting wounds.
Blood Composition
- Blood is a fluid tissue composed of proteins, ions, and cellular components.
- Blood is made of plasma and cellular components.
- Plasma is a watery matrix of ions and proteins (50-60% of total blood volume).
- Cellular components are different types of cells:
- Red blood cells (erythrocytes)
- White blood cells (leukocytes)
- Platelets (thrombocytes) (40-50% of total blood volume).
Blood Functions
- Transports nutrients, respiratory gases, hormones, and cellular wastes.
- Contains immune elements to protect against pathogens.
- Helps thermoregulation by distributing heat throughout the body.
ABO Blood Group System
- Type A: Has type A antigens on red blood cells (RBCs) and anti-B antibodies in the plasma.
- Type B: Has type B antigens on RBCs and anti-A antibodies in the plasma.
- Type AB: Has both type A and type B antigens on RBCs and no antibodies in the plasma (universal recipient).
- Type O: Has no A or B antigens on RBCs and both anti-A and anti-B antibodies in the plasma (universal donor).
Rh Blood Group System
- Rh-positive: Has Rh factor antigens on RBCs.
- Rh-negative: Lacks Rh factor antigens on RBCs. Can develop anti-Rh antibodies if exposed to Rh-positive blood (e.g., in pregnancy).
Blood Compatibility
- Compatibility for blood transfusions is critical. Blood type compatibility charts exist to prevent potentially severe reactions.
