![]() ![]() Bacteria residing in body tissues are swept up by the lymph and into lymphatic system “hubs” called lymph nodes, where these specialized white blood cells either produce antibodies against bacterial cells or directly attack them by engulfing and degrading them. Lymph contains high numbers of lymphocytes and macrophages - the immune system’s primary cellular defenses against invasion by bacteria and other microorganisms. Lymph circulation is therefore less consistent than blood circulation, although valves present in the larger vessels do keep the fluid flowing in one direction. Filtering and destroying invasive microorganismsĪlthough humans have no active mechanism for circulating lymph throughout the body, as the heart actively drives the blood, lymphatic flow is established passively by means of body movement and the contraction of skeletal muscles surrounding lymphatic vessels.Transporting fats from the digestive system to the blood.Returning proteins and extracellular substances from tissues to the bloodstream.Maintaining fluid balance within the body by removing excess interstitial fluid to the bloodstream.Primary functions of the lymphatic system include: Because the composition of interstitial fluid is in constant flux due to ongoing substance-exchange with the blood and surrounding cells, the composition of lymph varies accordingly. Lymph consists mostly of water originating from the interstitial fluid that surrounds cells and bathes the tissues of the body. Similar to plasma (the extracellular matrix of blood), lymph is a more or less colorless liquid that flows throughout a branched network of vessels, channels and ducts known as the lymphatic system.

In terms of composition, the interstitial fluid is similar to the blood plasma since the two continuously exchange substances across capillary walls. It provides a means of delivering materials to the cells, intercellular communication, and removal of metabolic waste. Its main function is to bathe and surround the cells of the body. It is composed of water, amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, and cellular products. Interstitial fluid has a very specific composition, compared with plasma, and is responsible for providing the oxygen and nutrients required by the. The interstitial fluid is the fluid that fills the spaces between cells. The interstitial fluid and the blood plasma are the major components of the extracellular fluid. cerebrospinal fluid, synovial fluid, aqueous humour, serous fluid, gut fluid, etc.). ![]() It is composed of blood plasm a, interstitial fluid, lymph and transcellular fluid (e.g. It makes up about 26% of the total body water composition in humans. The extracellular fluid pertains to all body fluid outside the cell(s). It bathes and surrounds the cells of the body, and provides a means of delivering materials to the cells, intercellular communication, and removal of metabolic waste. The fluid found in the intercellular spaces composed of water, amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, and cellular products. ![]()
