[Resistance, capacitance and exchange functions of the vessels of the small intestines and skeletal muscles during exposure of the body to intense heat].
Rise of body temperature to 41.0-41.2 degrees C led to an increase of the integral, pre- and postcapillary resistance in the vascular bed of the cat small intestine and skeletal muscles. The increase of the resistance function in veins led to an increase of the mean capillary hydrostatic pressure. The above shifts enhanced with increasing of the hyperthermia. The latter was found to reduce distensibility of veins and the capillary filtration coefficient (CFC) in the small intestine vascular bed but to increase the CFC in skeletal muscles. The role of the small intestine and skeletal muscles venous vessels in the shifts of the filtration-absorption ration and the capacitance function in hyperthermia is discussed.
