Chapter 12, Problem 24SAE
Summary Introduction
To review:
The definition of “immunocompetence” and give the indication when a B cell or T cell has developed immunocompetence. Give the location of the occurrence of the programming phase of the B cells.
Introduction:
Our body defense system works efficiently in providing protection against the pathogens. The third line of defense consists of T as well as B cells and the antibodies, which makes a part of cell-mediated and humoral immunity, respectively.

Correctly order the steps in cellular Immunity.
Below is a sequence of events. Place them in the order they should occur, number 1 being the first item. Select the step number from the drop down next to each item.
Items to order:
a) .Cytotoxic T cell (CTL) recognizes the infected host cell
b) The CTL secretes perforin and granzyme, causing apoptosis
c) The CTL interacts with epitope presented by MHC-I on the dendritic cell
d) The helper T cell activates the CTL cell
Explain why the B cells response is described as “humoral”, but the T cell’s response is described as “cell-mediated”?
Explain the two processes by which B-cells are activated to inactivate an antigen?
