Question

How do specificregions of the body

Answer 1

Answer:

• Immune system-

"The inbuilt system of the human body, which is responsible for dealing with any invading foreign bodies or pathogens."

• Two portions of the immune system are there;

1. The innate immune system,
2. The adaptive immune system.

Explanation:

• The innate immune system:

The innate immune system includes the number of line of defenses inside the human body, as they react to any pathogen invading the body system. As there are a number of cells which responds to any foreign particle entering the human body system.

The 1st line of defense: It mainly includes the skin, which covers most of the body and protects it from any pathogenic attack.

The 2nd line of defense:When the pathogen breaches the 1st line of defense then there are some cells called as white blood cells(WBC's) which encounter the foreign particles and inflammation is initiated on the site. The phagocytes attacks the pathogens and destroys it membranes and body.

• The adaptive immune system:

The Adaptive immune system is built by the system in order to tackle with any attack by the pathogen again in the future, as it stores some of the genetic strands sequence inside the body. As the Adaptive immune system consists of the B-cells and the T-cells, both of them works on a specific mechanism as they identifies the cells markers if they belong to the body, they will spare it or else an attack is carried out in it.
