Question

If the spleen is removed from the body of an adult man then
A. Antibody production will be less
B. RBC production will be lowered
C. WBC production will be lowered
D. Filtration of dead RBC will be stopped

Answer 1

Hint: The spleen can be found in almost all vertebrates. Serving mainly as a blood filter, it looks like a big lymph node. The blood vessels in the spleen expand and contract to meet the needs of the human body. It is a centre of operation for the mononuclear phagocyte system and functions similarly to a large lymph node in that its absence increases the risk of infection.

Complete answer:
The spleen is located near the liver, under the left rib cage. When the spleen is removed, other organs, such as the liver, usually take over much of the spleen's functions. Due to the importance of the spleen in the body's protection against germs, the patient is at a higher risk of infection after the procedure.
storing a reserve of blood that can be useful in the event of hemorrhagic shock, it recycles iron and replaces old red blood cells. Thus, It plays an important role in lymphocyte formation.

The spleen serves many vital functions:
- It battles germs in the bloodstream (the spleen contains infection-fighting white blood cells)
- It regulates the number of blood cells in the body (white blood cells, red blood cells and platelets)
- It cleans the blood and eliminates any red blood cells that are old or damaged.

Thus from the above discussion, it is clear that the correct answer is option D - Filtration of dead RBC will be stopped.

Note: The spleen measures 7 centimetres (2.8 in) to 14 centimetres (5.5 in) in length in healthy adults. It is possible to live without a spleen; in reality, 3,000 Australians currently live without a spleen or with diminished spleen function. Removal of the spleen is called a splenectomy, conditions that may require removal of the spleen include sickle cell disease, a hereditary disorder where red blood cells are shaped like crescent moons.
