Which of the following statements are true about T cells: (select all that apply)
T cells "mature" and become fully functional in the thymus
T cells are produced by stem cells in bone marrow
T cells are produced in the spleen
T cells "mature" and become fully functional in the tonsils
The Correct Answer is B
A. T cells "mature" and become fully functional in the thymus – T cells are produced in the bone marrow, but they mature in the thymus. In the thymus, T cells undergo a selection process to become functional and capable of recognizing specific antigens.
B. T cells are produced by stem cells in bone marrow – T cells originate from stem cells in the bone marrow, where they first begin to develop. However, they mature in the thymus.
C. T cells are produced in the spleen – This is incorrect. While the spleen plays a role in immune responses, T cells are not produced there; they are produced in the bone marrow.
D. T cells "mature" and become fully functional in the tonsils – This is incorrect. Tonsils are part of the lymphatic system and play a role in immune defense, but T cells do not mature there; they mature in the thymus.

C. Granulocytes are a type of white blood cell that includes neutrophils, eosinophils, and basophils, involved in the immune response.

Correct Answer is ["A","D"]
Explanation
A. Transfer through the placenta or breast milk is a form of naturally acquired passive immunity, where antibodies are passed from mother to child without the child's immune system having to produce them.
B. Inflammation is part of the innate immune response and not related to passive immunity.
C. Vaccination with an antigen involves stimulating the body to produce its own immune response, which is active immunity, not passive.
D. Administration of antiserum provides artificially acquired passive immunity, where pre-formed antibodies are given to an individual for immediate protection.
E. Tears and saliva are part of the innate immune system (first line of defense) and are not considered forms of passive immunity.
