Question

A disease-causing bacteria successfully enters your body, making it past the first and second lines of defense. What immune esponse will your body use to destroy the bacteria? A. chemical B. physical C. biological D. electrical

Answer 1

The correct answer is biological.

When any pathogen invades the body, it has to pass several line of defence. The first barrier is skin and mucous membrane which is a physical and chemical barrier. The second line of defence is non specific response by macrophages, neutrophills and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells acts specifically on the pathogen and destroys it.

Answer 2

The body will use the biological immune responses to destroy the disease-causing bacteria which crosses the first and second lines of defense.

What is the immune system?

The immune system is the system of organs and tissues as well as cells which work together to protect the body from diseases.

The first line of defence of the immune system is the skin an mucous membranes.

The second line of defense is the macrophages.

The third line of defense is the immune cells such as B-cells and T-cells which are biological immune responses.

Therefore, the body will use the biological immune responses to destroy the disease-causing bacteria which crosses the first and second lines of defense.
