Detailed explanation-1: -It is then transported through lymph vessels to lymph nodes, which clean and filter it. Lymph then flows on to the lymphatic ducts, before emptying into the right or the left subclavian vein, where it mixes back with blood.
Detailed explanation-2: -As a filter for the fluid that flows through your cells and tissues, lymph nodes clean up and get rid of lymphatic fluid waste and invaders that cause illness, while holding onto the components of your lymphatic fluid that keep you healthy.
Detailed explanation-3: -Antigens and dendritic cells (DCs) reach the draining lymph node through afferent lymphatic vessels; they must then enter the lymph node and migrate deep into it to activate T cells. Lymph nodes are enclosed in a collagen-rich capsule, which is underlined with lymphatic endothelial cells forming the subcapsular sinus.
Detailed explanation-4: -Bacteria (or their products) picked up from the tissues by cells called macrophages, or those that flow into the lymph, are forced to percolate through the lymph nodes. There, white blood cells called lymphocytes can attack and kill the bacteria.
Detailed explanation-5: -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.
