Question
Read the following statements and select the right option:I. The spleen is a large bean-shaped organ, which mainly contains lymphocytes and phagocytic cells.II. The principle of vaccination is based on the property of memory of the immune system.III. The graft rejection or failure of organ transplantation is due to cell- mediated immunity.IV. The yellowish fluid colostrum has an abundant amount of IgA antibody which provide active immunity to newborn babies.A I, II, III are correct B I, III, IV are correct C II and IV are correct D Only II is correct
Solution
The correct answer is B. Statements I, III, and IV are correct.
I. The spleen is indeed a large bean-shaped organ that contains lymphocytes and phagocytic cells.
III. Graft rejection or failure of organ transplantation is due to cell-mediated immunity. This is because the recipient's immune system recognizes the transplanted organ as foreign and attacks it.
IV. The yellowish fluid colostrum does contain a high amount of IgA antibody, which provides active immunity to newborn babies.
However, statement II is not entirely correct. While the principle of vaccination does involve the immune system's memory, it's more accurate to say that vaccination works by stimulating an immune response to an antigen, which the immune system then remembers if it encounters the antigen again in the future.
