The movement of lymph

The average weight of a human body with 60 kg has about 40 dm3 of water that is 25 dm3 in the intercellular and interstitial spaces. At night in the adult through the left thoracic duct alone and on an empty stomach lymph flows 1200-1500 cm3.
Lymph – a colorless liquid, alkaline, containing 3-4% of albumin, globulins, fibrinogen): colo 1.0% glucose, 0.8-0.9% of salts of mineral. The viscosity and its density is less than blood plasma. It contains lymphocytes, monocytes and eosinophils. Composition lymph unstable, it varies depending on the body from which it derives. Upon receiving the food containing much fat, lymph flowing from the alimentary canal, becomes milky white due to its content of emulsified fats from the liver – contains more protein, from endocrine glands – hormones. Lymph can be folded to form a loose cluster.

Lymph flowing from the small lymph vessels, enters the two flow: right and left. The left thoracic duct collects lymph vessels of both lower limbs of the entire abdominal cavity of the left half of the chest, left arm and left side of the head and neck.
Right duct collects lymph from the rest of the body. Both duct fall into a large vein, causing the lymph flows into the venous blood, and with it falls into the right heart. Lymph flow is very slow, in large lymphatics its speed 0.25-0.3 mm / min.
Lymph is moved by the rhythmic contractions of the walls of large lymphatic vessels (10-20 times 1 min), where it flows through the valve in one direction only. Large lymph vessels are innervated by sympathetic nerve fibers that cause them pain reflex constriction, emotions receptor stimulation of the internal organs, the pressure in the carotid sinus. The movement of lymph is further enhanced by the suction action of the chest and skeletal muscle contractions. Lymphization increases with the difference in osmotic pressures in the capillaries and tissue and decreases with an increase in oncotic pressure proteins in the bloodstream.

By lymphagogue include albumozy, chicken protein, histamine, extracts cancers, Fragaria et al., Limfoobrazovatelnuyu increasing function of the capillary walls. They also belong to the salt solutions, urea and sugar, which increases the osmotic pressure of blood.

The number of lymph increases:

    1) increase in blood pressure, 2) an improved inflow of arterial blood, 3) venous stasis, and 4) an increase in the total mass of the blood, 5) Strengthening the body.
The functions of the lymph nodes

In the course of the lymphatic vessels are the lymph nodes, which are innervated by sympathetic nerves. The lymph node lymphocytes and occurs phagocytosis of microbes and foreign substances. Some microbes caught in the lymph node, phagocytic cells reticulum and some delay in the node and gradually loses its virulence.
Neutralization of microbes occurs in the tonsils, which are among the seven are located around the throat.
During absorption from the gut into the lymph fall as nutrients and harmful. These substances pass through the first line of nodes in the intestinal wall, and the second and subsequent line of nodes in the mesentery.
