1 brain embolism: If a blood clot travels to the brain, this causes an ischemic stroke or TIA (transient ischemic attack).  retinal embolism: Small clots that wouldn't block a major artery can block the smaller blood vessels feeding the retina at the back of the eye. The result is usually sudden blindness in one eye.
At air temperatures between 14 and 30 degrees C, metabolic rate and body temperature decreased with air temperature, and metabolic rate showed an exponential relationship with body temperature (r2 = 0.74).The Q10 for metabolic rate was between 2 and 3 over the body temperature range of 16 to 32 degrees C.owever, the apparent conductance decreased with air temperature. At air temperatures below 14 degrees C, metabolic rate increased linearly with the decrease of air temperature (r2 = 0.58) and body temperature was maintained above 16 degrees C, largely independent of air temperature.
However it is not always true that the rate of a reaction increases with increase in temperature. Certain reactions like biological reactions which are catalyzed by enzymes may be slowed down with increase in temperature since the enzymes may lose their activity (see below for more explanation about a catalyst).
