Questions
Give three examples of scenarios that cause you to sweat
What is the source of your body's temperature?
What is the part of the brain responsible for regulating your temperature?
What is the immediate source of water for the sweat that the sweat gland produces?
The sweat that pools up from the sweat glands is usually hypotonic to the body fluids from which it came. Why is it advantageous for sweat to be less salty than body fluids?
All living cells are surrounded by fluid. If sweat comes from the fluid surrounding the cells of the sweat gland, then how does the body replace that fluid to keep those cells alive?
There is a link between the amount you sweat and the amount of urine you produce. How does the body coordinate these two responses?
Extension: Humans are unique among primates in our ability to sweat. What does this ability suggest about the origins of humans as we diverged from our ape ancestors?
