NEET BIOLOGY

Detailed explanation-1: -Most of the body’s organs remove dead cells and other waste using the lymphatic system. Lymphatic vessels run alongside blood vessels and transport out lymph, a colorless fluid containing infection-fighting immune cells and waste.

Detailed explanation-2: -Inside the lymph nodes are white blood cells, also called lymphocytes. These white blood cells attack and break down bacteria, viruses, damaged cells or cancer cells.

Detailed explanation-3: -The lymphatic system also helps defend the body against germs (viruses, bacteria, and fungi) that can cause illnesses. Those germs are filtered out in the lymph nodes, small clumps of tissue along the network of lymph vessels. Inside the lymph nodes, lymphocytes called T-cells and B-cells help the body fight infection.

Detailed explanation-4: -Lymph nodes mainly store immune cells that help the body fight infection but are also places where these cells can be made. They also filter the lymph fluid and remove foreign material such as bacteria and cancer cells.
