Okay, in the question, we have to look at this diagram and we have to label and also explain what is happening here.
00:06
As you can see here, this activated b cell, remember that this activated b cell can have like a phagocytosis function and also can present antigens to t cells.
00:19
Okay, so practically what is happening here is that this that this b cell that is activated is going to present, i mean, it already digested, the pathogen and it is presenting like an antigen from this pathogen to t cells.
00:37
Okay, so this t cells is going to receive or particularly this b cell is going to present the antigen to t cells and t cells are going to respond by secreting cytokines.
00:48
Okay, and these cytokines are going to stimulate this b cell in order for it to divide and become plasma cells.
00:55
Okay, in plasma cells, the function of plasma cells is to produce antibodies.
01:00
Okay, so this is what is happening here in this diagram...
