Final answer:
Respiration contributes to the obligatory water loss of the body.
Step-by-step explanation:
True.
Respiration involves the exchange of gases, with oxygen being taken in and carbon dioxide being released. During this process, water vapor is also produced. When we exhale, the water vapor carries with it some water molecules from our respiratory system, resulting in water loss. Therefore, respiration does contribute to the obligatory water loss of the body.
