Final answer:
False. The average sedentary adult typically has little problem keeping up with daily fluid needs.
Step-by-step explanation:
False
The statement 'The average sedentary adult typically has little problem keeping up with daily fluid needs.' is false.
On a typical day, the average adult takes in about 2500 mL (almost 3 quarts) of aqueous fluids. Additionally, each day about the same volume (2500 mL) of water leaves the body by different routes. The kidneys regulate water levels in the body, conserving water if the person is dehydrated and making urine more dilute to expel excess water if necessary.
