Chapter 43.2, Problem 2CC
Summary Introduction

To discuss: Two advantages of memory cells while encountering pathogen for the second time.

Concept introduction:

“B” lymphocytes and “T” lymphocytes are found in the blood. During the first invasion of a specific pathogen, both “B and T” cells divide rapidly and produce numerous identical cell clones. Some cells in that group are short lived, act directly upon the invading pathogen, and destroy them. The remaining cells are long lived, and they have registered the identity of that specific pathogen. They are called memory cells.
