What is the term for the amount of air in a breath?

• A. Blood Pressure
• B. Depth in Respiration
• C. Antecubital
• D. Brachial

Answer: (B)

Breathing has two main aspects: how often you breathe and how much air moves with each breath. The term that describes how much air is taken in (or expelled) in a single breath is the depth of respiration. When you breathe deeply, the depth increases; when you breathe shallowly, the depth is small. That’s exactly what this option communicates. The other choices don’t fit because they refer to parts of the body or to a measurement of blood flow, not to the amount of air per breath. If you’ve learned the more technical term tidal volume, that’s the precise volume per breath, but in this context the wording used corresponds to depth in respiration.
