Short note on Lymph.
Answers
Answer:
Lymph is a clear, colorless liquid with a composition similar to blood plasma. It is nothing but the clear, watery blood plasma leaked out through the capillary walls to flow around the cells. It contains oxygen, proteins, glucose and white blood cells.
All the cells bathed in this fluid receive their nutrients and oxygen from it. Tubular vessels transport lymph back to the blood, ultimately replacing the volume lost during the formation of the interstitial fluid.
Unlike the cardiovascular system, the lymphatic system is not closed and has no central pump.
Lymph movement occurs despite low pressure due to peristalsis, valves, and compression during contraction of adjacent skeletal muscle and arterial pulsation.
Answer:
Most components of blood plasma filter through blood capillary walls to produce interstitial fluid. After this interstitial fluid passes into the lymphatic vessels, it is called lymph.
Explanation:
- Vessels that transport the lymph are called lymphatic vessels.
- The major difference between interstitial fluid and lymph is location: Interstitial fluid (tissue fluid) is found between cells, and lymph is located within lymphatic vessels and lymphatic tissue.
- Its composition is similar to plasma except it lacks RBCs. It transfers materials from blood to the body cells and vice-versa, therefore acting as a 'middle man'.
