Hey friend here is your answer.....
Answer :
The Lymphatic system :
The lymphatic system plays a major role in the working of the immune system of the body . it consists of lymph , lymph vessels and lymph nodes, like the tonsils . The lymphatic system also includes the thymus gland and the spleen . Bone marrow also forms a part of the lymphatic system . The lymphoid organs and bone marrow produce a type of WBC called Lymphocytes , which produces antibodies In response to foreign bodies entering the blood . Lymphocytes also recognise and kill harmful self such as cancer cells and virally infected cells .
Lymph is a straw-coloured liquid formed from blood . Blood flows through the arterioles and capillaries under high pressure . The high pressure force is a clear fluid to pass through the thin walls of the capillaries and accumulate in the spaces between the neighbouring cells . This fluid is called tissue fluid . Tissue fluid supplies oxygen and nutrients to the surrounding cells and collects carbon dioxide and waste product from them . Accumulation of tissue fluid in the intercellular spaces old cause swelling within our body . Hence , tissue fluid is regularly removed from the intercellular spaces and flows into lymph capillaries as lymph . Lymph is essentially plasma carrying lymphocytes , waste products and cellular debris . It lacks RBCs , platelets and some proteins found in blood . Lymph capillaries join to form large lymph vessels . The lymph vessels ultimately drain into large range near the neck , thus transporting waste products and carbon dioxide into the blood stream . Lymph also carries digested fats from the small intestine into the blood vessels . These fats are transported to the liver for processing before being sent to the cells of the body via the systemic circulation .
The Lymph nodes are oval or kidney shaped masses of lymphatic tissue they are found throughout the body , particularly in the neck , armpits , groin and abdomen . The lymph nodes have large numbers of lymphocytes within them . The lymph nodes become swollen in response to infections and serious diseases like cancer . They filter and destroy bacteria and other harmful cells from the limit that passes through them .
