Abstract

The blood temperature in the main venous vessels reflects the formation of the heat balance in the body. In the rabbit posterior vena cava, the temperature increased by 0.19 degrees C-0.26 degrees C after confluence of the kidney and liver veins and decreased by 0.20 degrees C after confluence of the lumbal veins collecting the venous blood from the back muscles and skin vessels. The venous blood temperature in the right auricle was equal to blood temperature in the abdominal artery. When the ambient temperature changed from 22 degrees C-24 degrees C to 35 degrees C-40 degrees C, the temperature in the posterior vena cava and abdominal artery decreased by 0.25 degrees C-0.35 degrees C.

摘要

主要静脉血管中的血液温度反映了机体热平衡的形成。在兔后腔静脉中,肾静脉和肝静脉汇合后温度升高0.19℃ - 0.26℃,而收集背部肌肉和皮肤血管静脉血的腰静脉汇合后温度降低0.20℃。右心房的静脉血温度与腹主动脉中的血液温度相等。当环境温度从22℃ - 24℃变为35℃ - 40℃时,后腔静脉和腹主动脉中的温度降低0.25℃ - 0.35℃。
