Lymph is a clear fluid that is formed from the interstitial fluid that surrounds the body's cells. The formation of lymph begins when blood plasma leaks out of the capillaries and into the surrounding tissues. This fluid, known as interstitial fluid, contains water, electrolytes, proteins, and other substances that are necessary for the cells to function properly.
As the interstitial fluid collects in the tissues, it is then collected by the lymphatic vessels, which are a network of thin-walled tubes that run throughout the body. These vessels have one-way valves that prevent the fluid from flowing backwards, and they also have small lymph nodes along their path that filter out any bacteria, viruses, or other harmful substances.
Once the interstitial fluid enters the lymphatic vessels, it is then called lymph. Lymph is transported through the lymphatic system and eventually returns to the bloodstream through the thoracic duct or right lymphatic duct, where it is then circulated back to the heart and lungs.
Overall, the formation of lymph is essential for maintaining fluid balance in the body, transporting fats and fat-soluble vitamins, and helping to remove waste and toxins from the tissues.

Formation of Lymph:
Lymph is a fluid that circulates throughout the lymphatic system, parallel to the circulatory system. It originates from interstitial fluid, which bathes cells and tissues.
Process:
1. Filtration: As blood capillaries filter out nutrients, gases, and waste products, some fluid remains in the interstitial space. This fluid is known as interstitial fluid.
2. Uptake by Lymphatic Capillaries: Lymphatic capillaries, thin-walled vessels, are present in most tissues. They have small openings called stomata that allow interstitial fluid to enter the capillaries.
3. Formation of Prelymph: The interstitial fluid that enters the lymphatic capillaries is now referred to as prelymph.
4. Addition of Proteins and Other Substances: As prelymph flows through the lymphatic vessels, it picks up waste products, toxins, and other substances from the tissues. It also absorbs fat from the intestines and transports it to the bloodstream.
5. Formation of Lymph: Prelymph is eventually processed and filtered by lymph nodes. Lymph nodes contain immune cells that remove pathogens, dead cells, and other debris from the fluid. The filtered and purified fluid is now called lymph.
Circulation of Lymph:
Lymph flows through lymphatic vessels in a one-way direction towards the heart. It passes through several lymph nodes along the way, where it is filtered and cleansed. Once it reaches the heart, lymph is dumped into the bloodstream to be recirculated.
Functions of Lymph:
- Drains interstitial fluid and returns excess fluid to the bloodstream.
- Transports waste products, toxins, and pathogens for removal by the immune system.
- Absorbs fats from the intestines and transports them to the bloodstream.
- Participates in immune responses by carrying immune cells to targeted areas.
