Lymph is a colourless fluid containing lymphocytes which are involved in immune response of the body.

Line in NCERT: "Lymph is a colourless fluid containing specialised lymphocytes which are responsible for the immune responses of the body."

Lymph nodes produce both B-cells and T-cells. B-cells change to plasma cells that produce antibodies against invading antigens.

Lymph return the interstitial fluid back to the blood, This interstitial fluid, also called extracellular fluid, is filtered from og blood without its cellular component.

Line in NCERT: "As the blood passes through the capillaries in tissues, some water along with many small water soluble substances move out into the spaces between the cells of tissues leaving the larger proteins and most of the formed elements in the blood vessels. This fluid released out is called the interstitial fluid or tissue fluid. An elaborate network of vessels called the lymphatic system collects this fluid and drains it back to the major veins."

Lymphatic capillaries lie close to the blood capillaries and end blindly. Lymph does not flow in circular manner. Lymph from the lymphatic capillaries goes into the lymphatic vessels and then from the thoracic duct and right lymphatic duct it does into the left and right subclavian vein respectively.

Line in NCERT: "Lymph is a colourless fluid containing specialised lymphocytes which are responsible for the immune responses of the body."

Lymph is a fluid connective tissue containing lymph plasma and cells. The cells in lymph are floating amoeboid cells called WBCs (white blood cells) which are monthly lymphocytes. RBCs and platelets are absent in lymph.

Line in NCERT: "Lymph is a colourless fluid containing specialised lymphocytes which are responsible for the immune responses of the body. Lymph is also almost similar to blood except for the protein content and the formed elements."
