  • Title: [Effect of high ambient temperature on regional redistribution of blood flow in the cat].

    Journal: Fiziol Zh SSSR Im I M Sechenova; 1982 Mar; 68(3):385-90. PubMed ID: 7075841.
    Abstract:
    Supersound flowmetry revealed that the effect of heat (50 degrees C) involved an increase of the blood flow in skin vessels and its decrease in the vessels of small intestine and skeletal muscles. The blood flow resistance was diminished in skin vessels and increased in the vessels of small intestine and skeletal muscles. These shifts of the regional blood flow are due to the integral interaction of active and passive vascular responses. Specifics of the small intestine and skeletal muscle vessels' constrictory responses to hyperthermia suggest a difference in the mechanisms of their occurrence.
