Lymph is the fluid that circulates throughout the lymphatic system. It is formed when the Water and solutes can pass between the interstitial fluid and blood via diffusion across gaps in capillary walls called intercellular clefts; thus, the blood. What is the relationship between interstitial fluid, plasma, and lymph? When interstitial fluid enters blood vessels, it is called the blood plasma; when it enters the. Tissue fluid bathes the cells of a tissue (hence the name!). It is similar to blood but without the cells or plasma proteins. Its job is to transport.
Lymph contains white blood cells. In particular, the lymph that leaves a lymph node is richer in lymphocytes.
Relationship Between Tissue Fluid and Lymph
Likewise, the lymph formed in the human digestive system called chyle is rich in triglycerides fatand looks milky white because of its lipid content. Development[ edit ] Formation of interstitial fluid from blood Blood supplies nutrients and important metabolites to the cells of a tissue and collects back the waste products they produce, which requires exchange of respective constituents between the blood and tissue cells.
This exchange is not direct, but instead occurs through an intermediary called interstitial fluidwhich occupies the spaces between cells.
As the blood and the surrounding cells continually add and remove substances from the interstitial fluid, its composition continually changes. Water and solutes can pass between the interstitial fluid and blood via diffusion across gaps in capillary walls called intercellular clefts ; thus, the blood and interstitial fluid are in dynamic equilibrium with each other.
However, as it flows through the lymph nodes it comes in contact with blood, and tends to accumulate more cells particularly, lymphocytes and proteins. Lymph may pick up bacteria and bring them to lymph nodes, where they are destroyed. Metastatic cancer cells can also be transported via lymph.
The pressure inside the lymphatic capillaries is lower than that of blood capillaries and tissue fluid. Therefore, fluids in the blood capillaries tend to migrate into lymphatic capillaries via the tissue fluid. Small lymphatic capillaries join together to form larger lymphatic vessels. The lymph from legs, intestine and other organs, left arm, and the left side of head and neck is collected to the thoracic duct.
Lymph - Wikipedia
The lymph of the right arm and right side of the head and neck is collected by the right lymphatic duct. The thoracic duct and the right lymphatic duct drain their collections into left and right brachiocephalic veins respectively.
While flowing, bacteria and cancer cells are filtered through lymph nodes. The lymph capillaries in the tissue space are shown in figure 2.
Tissue fluid and lymph are typically colorless. Both tissue fluid and lymph often comprise a similar composition.

The flow of tissue fluid and lymph occur due to the muscular contractions in the body. Both tissue fluid and lymph are collected back and pushed back into the circulation.The significance of the tissue fluid and the lymphatic system for the transport of substances
Both tissue fluid and lymph are involved in maintaining the fluid balance of the body. Both tissue fluid and lymph ensure the removal of metabolic wastes. Tissue fluid is the extracellular fluid, bathing cells in the tissues, arriving into the blood capillaries, and being removed by the lymphatic system Lymph: Lymph is a colorless fluid, containing white blood cells, bathing tissues, and draining out through the lymphatic system into the circulation. Tissue fluid is found in the spaces between cells in tissues.
Lymph is found inside the lymphatic vessels.
Compare the composition of blood, tissue fluid, and lymph?
Tissue fluid ensures the supply of materials, nutrients, oxygen into the cells in tissues and organs, and removal of metabolic wastes from tissues. Lymph is involved in the removal of metabolic wastes and infectious organisms from tissues.
Tissue fluid may comprise phagocytes. Lymph may comprise lymphocytes. Tissue fluid does not contain fat. Lymph contains fats absorbed from lacteals in the intestine.
