Breathing in is medically described as which term?

• A. Inhalation
• B. Inspiration
• C. Ventilation
• D. Expiration

Answer: (B)

Breathing in is described by inspiration because it denotes the active process of drawing air into the lungs. Inspiration is the term used for the act of inhaling air, which involves chest expansion and the diaphragm contracting to pull air in. While inhalation also refers to air entering the lungs, many nursing and medical contexts use inspiration to describe the breathing-in phase. Expiration is the opposite—breathing out. Ventilation refers to the overall movement of air into and out of the lungs, not specifically the in-breath.
