If spleen of human is removed from body then

AAnimal will die
BNumber of blood platelets will increase
CNumber of blood platelets will decrease
DThere will be no effect on the number of blood platelets
Correct Answer

Solution

The spleen is a storage organ for red blood cells and contains macrophages which act to filter blood. If the spleen is removed, the platelets will remain in the blood stream. The spleen can also be the site of antibody production. Therefore removing the spleen may reduce the amount of anti-platelet antibodies in addition to removing the antibody-coated platelets. Although the spleen is often the major site of antibody-coated platelet destruction, platelets may also be removed from circulation by the liver. Hence there will be no effect on the number of blood platelets.
So, the correct answer is option D.
