Chapter 29, Problem 6MCQ
Summary Introduction
Introduction:
The body contains a well-defined immune system to protect itself from harmful pathogens. The harmful pathogens that attack the body are termed as antigen. However, the body produces certain cells to protect it from the invading pathogens. These cells are termed as antibodies. The antibodies are also referred to as immunoglobulin. They play a crucial role in immunity system as they have the capability to kill the invading pathogens.
