Lymph

Lymph is the fluid circulating in the intercellular spaces, lymphatic vessels and capillaries, the chemical composition of which is close to the composition of blood plasma, tissue, cerebrospinal and other body fluids. The most important difference lymph from blood plasma is more low protein content. The total protein content varies in different parts of the lymphatic system, is on average about half of the content in the plasma. Albumin-globulin ratio (see) lymph usually slightly higher than in the blood plasma. The concentration of individual amino acids in the lymph almost the same as in serum. In the lymph available in a small number of cellular elements, which are dominated by lymphocytes. The viscosity of lymph in connection with a lower content of protein is less than the viscosity of blood plasma. The reaction of lymph slightly alkaline. Lymph contains fibrinogen and prothrombin, decreases slower than the blood.
The role of lymph in the organism is to supply to the cells and tissues of nutrients and removal of metabolic products. The digestion of food in the body in the lymph dramatically increases the fat content (its content in the thoracic duct lymph, for example, reaches its maximum after 6 hours. after a meal).
Lymph from a starving - transparent or slightly opalescent liquid cloying smell and salt to taste. In the lymph taken from a separate bodies, the concentration of secreted by them of substances can be much greater than in the mainstream of blood. So, lymph, flowing from the thyroid gland, pituitary gland, etc., rich appropriate hormones. Easily pass into the lymph poisons and toxins, especially bacterial. It is established that the fundamental objective of the lymph enters the blood.

Lymph (from lat. lympha - clean water, moisture) - the liquid contained in the lymph vessels and capillaries. The chemical composition of lymph close to the composition of blood plasma, tissue fluid, cerebrospinal, synovial, amniotic and other body fluids. Some differences in the composition of these liquids depend mainly on different permeability separating them from blood and from each other membranes. The composition L. taken from various parts of the body, is also variable, which is connected with the allocation of a number of substances in Leningrad defined authorities and with different absorption of individual components L.
The most important difference lymph from blood plasma is more low protein content. Albumin-globulin ratio L. usually slightly higher than in the blood plasma. The total protein content varies in different departments of lymph flow and an average of about half of its content in the blood plasma. General osmotic concentration in Leningrad higher and colloid-osmotic pressure lower than in serum.
The concentration of individual amino acids in Leningrad almost the same as in the serum, and experimentally discovered oscillations are not natural. During digestion, the concentration of suction from the intestines substances in the lymph. increases considerably. In the hilus (L. mesenteric ducts) dramatically increases the fat content, while concentration of carbohydrates increases less, and protein - only slightly. A significant portion of fat absorbed from the intestine through the lymph system. The fat content in the thoracic duct lymph from reaches its maximum after about 6 hours after eating and may be many times higher than the initial concentration of fat in L.
In the lymph separate organs concentration securerom their substances can be much greater than in the mainstream of blood. So, L., flowing from the thyroid, pituitary, pancreas, and so on, are especially rich in relevant hormones. In this regard, a number of authors speaks of "lymphokine", i.e. separation of hormones in L. Therefore, the introduction of various toxins and other antigens causes the formation of antibodies to L. the same area earlier than in the blood.
