Question

Give the functions of lymph.

List the three functions of lymph.

Write any two functions of Lymph.

State two major functions of lymph.

Answer 1

1. Nutritive: It supplies nutrients and oxygen to parts of the body where blood cannot reach them.
2. Drainage: It removes excess tissue fluid and metabolites and returns proteins from tissue spaces to the blood.
3. Absorption: It absorbs fats from the intestine via the lymphatic system.
4. Defence: Lymphocytes and monocytes of the lymph function to protect the body. The lymphatics also remove bacteria from the tissues.

Answer 2

1. It helps distribute nutrients.
2. It transports lymphocytes from lymph glands to the blood.
3. It helps regulate body temperature.
4. It contains antibodies that kill infections and protect the body from disease. 
5. It helps eliminate nitrogenous waste.

Answer 3

1. Immune System Support:
   1. Lymph transports white blood cells (including lymphocytes) throughout the body. These cells play a crucial role in the immune system, identifying and killing pathogens such as bacteria, viruses, and aberrant cells.
   2. Lymph nodes, located along lymphatic channels, filter and eliminate foreign particles and antigens.
2. Fluid Balance and Tissue Health:
   1. Lymphatic vessels remove interstitial fluid from tissues to prevent fluid buildup and preserve tissue health.
   2. Lymphatic fluid is collected and transmitted through lymphatic channels before returning to the bloodstream to maintain fluid balance in the body.

The lymphatic system plays a key role in immune defence and fluid homeostasis inside tissues.
