Question

which of the following is not a way that water enters the body?
a in what we drink
b in what we eat
c from body metabolism
d in the air we inhale

Explanation:

To determine the answer, we analyze each option:

• Option A: Drinking liquids (like water, juices) is a primary way water enters the body.
• Option B: Many foods (e.g., fruits, vegetables) contain water, so water enters via food.
• Option C: Metabolic processes (e.g., cellular respiration) produce water as a by - product, which enters the body's water pool.
• Option D: The air we inhale is mainly for oxygen intake, and the water content in inhaled air is not a significant way for water to enter the body (unlike the other three options which are established routes of water intake).

Answer:

D. In the air we inhale
