Question

question 9 of 10
which would cause the body to release more water through the excretory system?
a. losing salt through the skin
b. jogging in a gym
c. eating salty foods
d. sweating on a hot day

Explanation:

When a person eats salty foods, the salt (sodium chloride) is absorbed into the bloodstream. This increases the concentration of solutes in the blood. To maintain the body's fluid balance (osmoregulation), the kidneys will excrete more water to dilute the excess salt. This process causes the body to release more water through the excretory system (urine).

• Option A: Losing salt through the skin (e.g., in sweat) would not directly cause the body to release more water through the excretory system. If anything, it might lead to the body conserving water to maintain the proper salt - water balance.
• Option B: Jogging in a gym might cause sweating (losing water through the skin), not an increase in water release through the excretory system.
• Option D: Sweating on a hot day is water loss through the skin (integumentary system), not the excretory system (kidneys, ureters, bladder, urethra).

Answer:

C. Eating salty foods
