Answer:

The function of the human immune system is to protect us.

Explanation:

The function of the immune system is to protect us from the viruses, bacteria and infections that live around us. The immune system is in charge of attacking and destroying everything that could harm us, which is called antigen.

The immune system will react through inflammation where the white blood cells go throughout the body to where the antigen is found and "ask for reinforcements" of more white blood cells.

Once the threat disappears, the inflammation subsides.
