[Contractile activity of pectoral channel and lymph nodes in rats under antiorthostatic influences]

It has been established that during short term body antiorthostatic positions lymphatic system carries out compensatory function, unloading the cardiovascular system from redundant exercise. The contractile activity of pectoral channel and lymphatic nodes in weightlessness (antiorthostatic influence) was studied. The functional role of neck lymph nodes is expressed by depositing of liquid during redistribution of the blood. The atony of neck lymph nodes as well as loss of pectoral channel and lymph nodes decrease the receptor sensitivity of vessels and nodes to the action of vasoactive substances.
