Summary Introduction

To explain:

The reason whether a deficiency of $\text{T}$ cells or a deficiency of $\text{B}$ cells will be more dangerous for a human.

Concept Introduction:

$\text{T}$ cells are of two types namely cytotoxic $\text{T}$ cells and helper $\text{T}$ cells. These cells are activated during the exposure of the foreign antigens which causes the development of the memory and effector cells. The $\text{B}$ cells are also activated by the priming mechanism which forms the effector and memory cells.
