IMMUNOLOGY

Detailed explanation-1: -Lymph nodes: Lymph nodes are bean-shaped glands that monitor and cleanse the lymph as it filters through them. The nodes filter out the damaged cells and cancer cells. These lymph nodes also store lymphocytes and other immune system cells that attack and destroy bacteria and other harmful substances in the fluid.

Detailed explanation-2: -The lymph nodes filter out harmful substances and waste products. They also contain immune cells called lymphocytes that destroy cancer cells and bacteria. The filtered fluid is then returned to the blood circulation.

Detailed explanation-3: -Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body. They are connected to one another by lymph vessels.

Detailed explanation-4: -Most of our lymph nodes are in clusters in the neck, armpit, and groin area. They’re also found along the lymphatic pathways in the chest, abdomen, and pelvis, where they filter the blood. When a person has an infection, germs collect in the lymph nodes.

Detailed explanation-5: -Lymph fluid flows through the tissue that makes up lymph nodes, where the tissue filters and recycles lymph fluid that your body needs. The cells within your lymph nodes will attack, destroy and eliminate waste, especially foreign invaders, to help your immune system keep you healthy.

Detailed explanation-6: -Lymph nodes, lymph vessels, and other lymphatic organs help to prevent fluid build-up in tissues, defend against infection, and maintain normal blood volume and pressure in the body.

Detailed explanation-7: -Lymph nodes filter lymph of harmful pathogens such as bacteria and viruses. The nodes also filter out cellular waste, dead cells, and cancerous cells. The filtered lymph from all areas of the body is eventually returned to the blood through a blood vessel near the heart.
