Generates and transmits impulses

Correct Answer is D
Explanation
a. Activation of plasmin: Plasmin is involved in breaking down blood clots, not in their formation. It is part of the fibrinolytic system.
b. Activation of heparin: Heparin is an anticoagulant that prevents clotting; it is not required for blood clotting.
c. Adequate levels of potassium: Potassium is important for cellular function but does not play a direct role in blood clotting.
d. Adequate levels of calcium: Calcium ions are essential for various steps in the blood clotting cascade, including the activation of certain clotting factors.
Correct Answer is A
Explanation
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.
