B-lymphocytes in birds are produced from
B-lymphocytes in birds are produced from
Show Hint

- Kidney
- Bursa of Fabricius
- Keel
- Heart
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding lymphocytes.
Lymphocytes are immune cells responsible for antibody production and adaptive immunity. They include B-cells and T-cells.
Step 2: Origin of B-lymphocytes in birds.
In birds, B-lymphocytes mature and are produced in a specialized lymphoid organ called Bursa of Fabricius.
Step 3: Function of Bursa of Fabricius.
It is present only in birds and plays a key role in differentiation of B-cells. It is analogous to bone marrow in mammals.
Step 4: Evaluation of other options.
Kidney, keel, and heart are not lymphoid organs and do not produce immune cells.
Step 5: Immunological significance.
Proper B-cell development is essential for antibody-mediated immunity in birds.
Step 6: Final conclusion.
Thus, B-lymphocytes in birds are produced from Bursa of Fabricius.
Lymphocytes are immune cells responsible for antibody production and adaptive immunity. They include B-cells and T-cells.
