What term describes abnormally prolonged and deep breathing?

• A. Hyperapnea
• B. Tachypnea
• C. Hyperventilation
• D. Bradypnea

Answer: (C)

Understanding breathing patterns involves separating how fast the breaths are from how deep they are. Hyperventilation describes breathing that is both deeper and faster than normal, i.e., ventilation that exceeds the body’s immediate needs. This means breaths are longer and move more air per breath, which fits “abnormally prolonged and deep” better than simply breathing quickly (tachypnea) or slowly (bradypnea). Hyperpnea refers to increased depth and rate due to metabolic demand (like exercise), but in many exam contexts hyperventilation is the term used for the pattern of unusually long, deep breaths that goes beyond normal needs.
