Question

The immune system of our body is activated in response to infection. It first recognises the pathogen by its receptors and try to kill it with different enzymes.

Answer 2

The Immune System of our body is activated in response to infection.

• The immune system in our body functions to defend against the disease-causing germs. It is a vast network of organs, cells, and proteins that work together to protect our bodies.
• If an antigen enters our body, an antigen is anything that triggers our immune system, B-cells in our bodies recognize it then it produces antibodies.
• When the antibodies attach to antigen, it signals other parts of the immune system to destroy them.
• But some germs are adaptive and find ways to change over time. This is the reason we get flu shots.
