Blood Types
Guided Notes
3 key concepts
- 1
Blood types are determined by the presence of specific proteins, also known as antigens, on the surface of red blood cells (erythrocytes).
- 2
Type A blood has A proteins and anti-B antibodies, while type B blood has B proteins and anti-A antibodies.
- 3
A person with type O-negative blood is considered a universal donor because their blood lacks A, B, and Rh antigens, while a person with type AB-positive blood is considered a universal recipient.
