Why is immune system essential for our health?

Answers (1)

The immune system has a significant role in protecting our body against germs, harmful substances and cell changes which lead to illness in an individual. The immune system consists of cells, organs and proteins.

The absence or poor immune system can leave an individual’s body unprotected against the harmful substances which enter inside or affect from outside onto our system.

The primary tasks that an immune system does for our health care:

  1. Fight against diseases caused by viruses, fungi, parasites and bacteria.
  2. Fight against diseases which cause cell changes in the body such as cancer cells.
  3. Identifies and counterbalances threats in the environment.

The immune system gets activated whenever our body comes into contact with harmful things and prevents it from damaging the body. Thus, the immune system is essential for our health.
