AInsensible water loss
BObligatory water loss
CSensible water loss
DMetabolic water loss
Answer & Solution
Correct answer: A. Insensible water loss
1. Some water leaves through the skin with no visible sweating, and some leaves in exhaled air.
2. A person is normally unaware of either route, so the loss is called insensible.
3. Metabolic water is water generated by aerobic respiration, so it is a gain and not a loss.
4. Sweat that a person can see or feel is a separate, sensible route.
