ANATOMY

Detailed explanation-1: -A healthy immune system can defeat invading disease-causing germs (or pathogens), such as bacteria, viruses, parasites-as well as cancer cells-while protecting healthy tissue. Understanding how the immune system works and how we can help protect our bodies is essential to the fight against the COVID-19 pandemic.

Detailed explanation-2: -Immunity is the ability of the body to defend itself against disease-causing organisms. Everyday our body comes in contact with several pathogens, but only a few results into diseases. The reason is, our body has the ability to release antibodies against these pathogens and protects the body against diseases.

Detailed explanation-3: -Your immune system is a large network of organs, white blood cells, proteins (antibodies) and chemicals. This system works together to protect you from foreign invaders (bacteria, viruses, parasites, and fungi) that cause infection, illness and disease.

Detailed explanation-4: -White blood cells are the key players in your immune system. They are made in your bone marrow and are part of the lymphatic system. White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi.
