ANATOMY

Detailed explanation-1: -The spleen acts as a filter. It weeds out old and damaged cells and helps control the amount of blood and blood cells that circulate in the body. The spleen also helps get rid of germs. It contains white blood cells called lymphocytes and macrophages.

Detailed explanation-2: -Lymph nodes are small clumps of tissue along the network of lymph vessels that clean lymph as it moves through them. They filter out viruses, bacteria, and fungi that can cause illnesses. Most lymph nodes are in clusters in the neck, armpit, and groin area.

Detailed explanation-3: -What do Lymph Nodes do? They filter out impurities, such as carbon and dead blood cells, as well as harmful matter, such as bacteria and cancer cells. Lymph nodes also produce lymphocytes, which are special white blood cells, and antibodies, which are substances used to fight infection.

Detailed explanation-4: -Lymph nodes are small, bean-shaped masses of lymphatic tissue along lymph vessels. They store lymphocytes and filter waste, bacteria and damaged cells (including cancer cells) from lymph. The lymphocytes inside the lymph nodes also attack bacteria and viruses that they find in the lymph.

Detailed explanation-5: -Lymphocytes develop in the thymus and bone marrow (yellow), which are therefore called central (or primary) lymphoid organs.
