A person with type AB blood can successfully receive blood from:
All blood types.
Only type O blood.
Only two of the blood types.
Only one of the blood types.
The Correct Answer is A
A person with type AB blood can successfully receive blood from all blood types.
This is because type AB blood has both A and B antigens on the surface of red blood cells, and therefore does not have antibodies against either antigen in the plasma.
Type AB blood is also called the universal recipient.
Choice B is wrong because type AB blood can receive more than just type O blood.
Type O blood is the universal donor, meaning it can be given to anyone, regardless of their blood type.
Choice C is wrong because type AB blood can receive more than just two of the blood types. Type AB blood can receive both A and B blood, as well as O and AB blood.
Choice D is wrong because type AB blood can receive more than just one of the blood types. Type AB blood can receive any blood type without problems.
Normal ranges for blood types vary by population, but generally, type O is the most common, followed by type A, type B, and type AB.

Correct Answer is C
Explanation
This sequence ensures that the atria contract before the ventricles and that the ventricles contract from the bottom up.
Choice A is wrong because it reverses the order of the SA node and the AV node. The SA node is the pacemaker of the heart and initiates the cardiac impulses.
Choice B is wrong because it places the Purkinje fibers before the AV node.
The Purkinje fibers are the last part of the conduction system and stimulate the ventricular muscle fibers.
Choice D is wrong because it reverses the order of the entire sequence.
The AV node is not the pacemaker of the heart and does not initiate cardiac impulses.
Correct Answer is C
Explanation
The thymus gland is an essential part of the immune system that produces and matures T cells, a type of white blood cell that defends the body from infections.
Thymosins also regulate immune cell production and inhibit aging.
Choice A is wrong because thyroxines are hormones produced by the thyroid gland, not the thymus gland.
Thyroxines control metabolism and affect growth and development.
Choice B is wrong because melatonins are hormones produced by the pineal gland, not the thymus gland.
Melatonins control circadian rhythms and sleep cycles.
Choice D is wrong because prostaglandins are not hormones, but lipid compounds that have hormone-like effects.
Prostaglandins control inflammation, blood pressure, muscle contraction, and other functions.
