What type of blood has A antigens on red blood cells?

• Type AB

• Type B

• Type A

• Type O

Answer explanation

Type A blood has A antigens on its red blood cells. Type AB has both A and B antigens, Type B has only B antigens, and Type O has neither. Therefore, the correct answer is Type A.

Which blood type has B antigens on red blood cells?

• Type AB

• Type O

• Type B

• Type A

Answer explanation

Type B blood has B antigens on red blood cells. Type AB has both A and B antigens, Type O has neither, and Type A has only A antigens. Therefore, the correct answer is Type B.

Which blood type doesn't have A or B antigens?

• Type A

• Type B

• Type AB

• Type O

Answer explanation

Type O blood does not have A or B antigens on the surface of its red blood cells, making it the only blood type without these antigens. In contrast, Type A has A antigens, Type B has B antigens, and Type AB has both.

Which blood type can't receive type B or AB blood?

• Type B

• Type A

• Type O

• Type AB

Answer explanation

Type A blood has anti-B antibodies, which means it cannot receive type B or AB blood. Therefore, the correct answer is Type A.

Which blood type is a universal donor?

• Type AB

• Type B

• Type O

• Type A

Answer explanation

Type O is considered the universal donor because it has no A or B antigens on the red blood cells, allowing it to be safely transfused to any blood type without causing an immune reaction.

Which blood type is a universal recipient?

• Type AB

• Type A

• Type B

• Type O

Answer explanation

Type AB is the universal recipient because it has both A and B antigens on the red blood cells, allowing it to accept blood from any type without triggering an immune response.

Which blood type is a universal recipient?

• Type AB

• Type A

• Type B

• Type O

Answer explanation

Type AB blood is considered the universal recipient because it has both A and B antigens on the red blood cells, allowing it to accept blood from any other type without triggering an immune response.

Which blood type is considered the universal recipient?

• B negative

• O negative

• A positive

• AB positive

Answer explanation

AB positive is considered the universal recipient because it has both A and B antigens and the Rh factor, allowing it to accept blood from any type without risk of rejection.

What are antigens in the context of blood types?

• Substances found on the surface of red blood cells that can trigger an immune response

• Enzymes that break down antigens in the blood.

• Proteins that transport oxygen in the blood.

• Hormones that regulate blood pressure.

Answer explanation

Antigens are substances on the surface of red blood cells that can trigger an immune response. They determine blood types and can cause reactions if blood from different types is mixed.

Which blood vessel carries blood AWAY from the heart?

• Veins

• Arteries

• Capillaries

• None of these

Answer explanation

Arteries are the blood vessels that carry blood away from the heart, delivering oxygen-rich blood to the body's tissues. In contrast, veins carry blood back to the heart, and capillaries are small vessels where exchange occurs.
