Document Summary
Bpk 375 week 12 lecture: temperature regulation and metabolism. Metabolism: chemical reactions: heat & energy. Heat loss: radiation, conduction, conv ect ion 70, evaporation (skin & lungs) Control: hypothalamus, peripheral receptors, comparison of core and peripheral temperatures. Mechanisms of shivering & sweating are poorly developed. Ability to generate helps you in preventing you from getting cold. There have been several deaths of adolescent athletes: intense prolonged activity, high ambient temperature & humidity, athletic equipment, big (small s. a. /weight ratio, lack of water. Water leaves blood, decrease in blood volume. Chemical reactions of the body: reaction= energy + heat. Direct calorimetry: sealed chamber where all inputs and outputs are monitored. Spirometer for oxygen uptake: ok for low levels of oxygen uptake. Breathing in a certain volume of oxygen, volume of oxygen that is expired. Carbohydrate: c6h12o6 + 6o2 --> 6co2 + 6h2o, r = 6co2 / 6o2 = 1. 0.
