Essay Questions

1) Tom loves to soak in hot tubs and whirlpools. One day, he decides to raise the temperature in his hot tubas high as it will go. After a few minutes in the very warm water, he feels faint, passes out, and nearly drowns.Luckily, he is saved by an observant bystander. Explain what happened physiologically.Answer: In response to the high temperature of the water, Tom's body shunted more blood to the superficialveins to decrease body temperature. The dilation of the superficial veins caused a shift in blood to the armsand legs and resulted in a decreased venous return. Because of the decreased venous return, the cardiacoutput decreased and less blood with oxygen was delivered to the brain. This caused Tom to feel lightheadedand faint, nearly causing his demise.Diff: 2Learning Outcome: 13.10
