Hi, in this question, you are given five organs or systems found in mammals, and you need to identify which one is not directly involved in immune responses.
00:16
So let's see.
00:17
Our first offering there is the thymus.
00:20
The thymus is very important because it is important in t -cell production.
00:34
So it can produce t -cells and also, so t cells mature there and are specialized.
00:47
The next one is bone marrow.
00:51
Bone marrow is definitely important because bone marrow produces blood cells, both red cells and, of course, white cells, which are important to the immune response.
01:07

01:11
