Structure and Function of Blood

A
  • Complex mixture of cells, water, proteins and sugars.
  • Transports nutrients, oxygen and hormones all over body
  • Helps regulate body temperature
  • Maintain stability of body’s fluid volume
  • Transports waste products away from body cells.

Q

Blood Typing

A

Transfusions of blood rarely worked until the “typing” of blood was developed.

Tested for type to prevent agglutination of clumping of blood cells (transfusion reaction)

Q

4 Types of Blood

A

Based on which Antigen (Ag) is present in RBC

  • Type O: No Antigens Present (Both Antibodies)
  • Type A: “A” Antigen present (“B” antibodies)
  • Type B: “B” Antigen present (“A” antibodies)
  • Type AB: “A & B” Antigen present (No Antibodies

Type O is universal donor.
Type AB is universal recipient
