ANATOMY

Detailed explanation-1: -All throughout the body, disease fighting cells are stored in the immune system waiting for the signal to go to battle. The immune system is able to communicate throughout the entire body. When pathogens are detected, messages are sent out, warning that the body is being attacked.

Detailed explanation-2: -Leukocytes patrol the blood and tissues throughout the body in search of intruders. When they detect a foreign substance, they send out signals and launch an immune attack. These disease-fighting cells are made in the bone marrow and are stored in many different places in the body such as the tonsils and adenoids.

Detailed explanation-3: -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.

Detailed explanation-4: -What is the immune system? The immune system protects your child’s body from outside invaders. These include germs such as bacteria, viruses, and fungi, and toxins (chemicals made by microbes). The immune system is made up of different organs, cells, and proteins that work together.

Detailed explanation-5: -Together, cytokines and antigens train individual adaptive immune cells to recognize and destroy specific patterns of each foreign invader. First, they instruct the adaptive immune cells how to respond to the invader by releasing chemicals called cytokines.
