INTERCELLULAR LYMPH

From Big Medical Encyclopedia

INTERCELLULAR LYMPH — the intermediate fluid medium filling intercellular spaces of all fabrics. Nek-ry researchers carry to T. cerebrospinal liquid (see), the watery moisture filling front and back chambers of the eye (see. Hydrodynamics of an eye ), etc. Total quantity of an intercellular lymph in a human body makes 23 — 29% of the weight (weight) of a body.

T. it is formed from blood plasma (see) under the influence of a gradient osmotic and the hydrostatic pressure of blood in capillaries, walls to-rykh have high-permeability. But it is close to chemical structure to a blood plasma, from a cut differs in smaller protein content (apprx. 1,5 g in 100 ml), and includes the nutrients necessary for cells, and also products of fabric exchange. Structure of T. it is constantly updated due to intake of liquid from a blood plasma of capillaries in intercellular space p in the opposite direction — in post-capillaries and venules. However in general chemical structure and biol. properties T. are rather constant (see. Homeostasis ), and T. separate bodies according to their morfofunktsionalny features the nek-swarm differs in specificity.

In regulation of number of T. an important role is played by gistogematichesky barriers (see. Barrier functions ), and in maintenance at the certain level of an osmotic and ionic homeostasis of internal environment of an organism — intercellular substance of connecting fabric (see. Intercellular substance ).

At receipt in limf, capillaries of T. turns in lymph (see).
