Hello everyone, in this question we have been asked that which organs are b cells developed in? so, this here is developed in the primary lymphocyte which are the bone marrow or the thymus.
00:12
So, here the b cell is originated in the bone marrow.
00:16
So, our right answer is option b that is bone marrow.
00:21
Then in the next question it says that hematopoietic stem cells differentiate into which two cell line? so, the hscs basically differentiate into the myeloid progenitor as well as the lymphoid progenitor.
00:39
So, here our right answer will be option b that is myeloid and the lymphoid and then further it is differentiated into the rbcs, platelets, myeloblasts, monoblasts, the lymphoblasts.

Then in the next question it says that in general the adaptive immune response will be much larger when the individual has a second exposure to an antigen.
01:06
So, what will happen to the innate immune response upon secondary exposure to an antigen? so, basically the innate immunity is the first line of defense.
01:18
There is no memory cells that is produced and there is no antibody also that is produced.
01:24
So, this here will always be the same...
