Blood Types Physiology (ABO and Rh Blood Groups)

Leslie Samuel explains the physiology behind blood types, focusing on the ABO and RH blood groups. The video covers how the immune system works, the role of antigens and antibodies, and the implications for blood transfusions. It highlights the importance of matching blood types to prevent adverse reactions and identifies universal donors and recipients. The video concludes with a call to action to share the knowledge.

What is the primary function of antibodies in the immune system?

• To create red blood cells

• To transport oxygen

• To attack foreign invaders

• To produce antigens

Which blood type has both A and B antigens on the surface of red blood cells?

• Type O

• Type B

• Type A

• Type AB

Why is it dangerous for a person with type A blood to receive type B blood?

• Type B blood has anti-A antibodies

• Type B blood lacks antibodies

• Type A blood has anti-B antibodies

• Type A blood lacks antigens

Which blood type is considered a universal recipient?

• Type B

• Type A

• Type O

• Type AB

What is the main characteristic of Type O blood that makes it a universal donor?

• It has both A and B antigens

• It has only A antigens

• It lacks both A and B antigens

• It has only B antigens

What happens if an RH negative person receives RH positive blood?

• They become RH positive

• They produce RH antibodies

• They produce RH antigens

• Nothing happens

Which blood type is considered the universal donor in the RH blood group system?

• Type O Positive

• Type AB Negative

• Type O Negative

• Type AB Positive
