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 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."

• p. Lymph → f. Tissue Fluid
  Correct. Lymph is derived from tissue fluid.

• q. Mixed Blood → e. Amphibians
  Correct. Amphibians have a three-chambered heart that results in mixing of oxygenated and deoxygenated blood.

• r. Fibrins → h. Blood Clot

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."

Statement (a) is correct. Lymph plays a crucial role in absorbing fats from the intestine through specialized lymphatic vessels.
Statement (b) is incorrect. Fibrinogen is produced by the liver, not by lymph nodes.
Statement (c) is correct. The lymphatic capillaries in the intestinal villi are known as lacteals, and they absorb dietary fats.
Statement (d) is incorrect. Lymph does not transport oxygen; this function is carried out by blood, specifically by red blood cells.
