An individual with which of the following blood types can receive all types of blood?
AB positive
A positive
B negative
O negative
The Correct Answer is A
a. AB positive: Individuals with AB positive blood are universal recipients. They have A and B antigens on their red blood cells but no antibodies (anti-A or anti-B) in their plasma. Therefore, their body will not reject blood types A, B, AB, or Rh positive or negative.
b. A positive: Individuals with A positive blood can only receive A positive or O positive blood. Their plasma contains anti-B antibodies, which would attack blood types B and AB.
c. B negative: Individuals with B negative blood can receive B negative or O negative blood. Their plasma contains anti-A antibodies, which would attack blood types A and AB. The Rh factor is another compatibility consideration, but the question specifies positive.
d. O negative: Individuals with O negative blood are universal donors but not universal recipients. Their red blood cells lack A and B antigens, so they can be donated to anyone. However, their plasma contains anti-A and anti-B antibodies, so they can only receive O negative blood.

Correct Answer is A
Explanation
a. Pyloric sphincter: This sphincter regulates the passage of chyme from the stomach into the duodenum.
b. Lower esophageal sphincter: This sphincter prevents the backflow of stomach contents into the esophagus.
c. Ileocecal sphincter: This controls the flow of material from the ileum of the small intestine into the cecum of the large intestine.
d. Internal anal sphincter: This sphincter controls the release of feces from the rectum but is not involved in the release of chyme
Correct Answer is C
Explanation
a. The right ventricle chamber has a smaller overall capacity than the left ventricle: While true, this doesn't directly explain the difference in muscle thickness.
b. The right ventricle receives blood from right atrium, which has lower pressure than left atrium: Both ventricles receive blood from low-pressure atria. The pressure difference is between the circulation systems they pump blood into.
c. The right ventricle pumps a smaller blood volume than the left ventricle. The right ventricle pumps blood to the lungs, a low-pressure system. Therefore, the right ventricle wall (myocardium) is thinner than the left ventricle wall. The left ventricle pumps blood against the higher resistance of the systemic circulation, so its wall is much thicker and stronger.
d. The right ventricle pumps blood into pulmonary circulation, which has lower resistance than systemic circulation: This is the core reason for the difference in muscle thickness.
