Which term is defined as the delivery of oxygen to the bloodstream?

• A. Anatomy
• B. Oxygenation
• C. Physiology
• D. Tissue

Answer: (B)

Oxygenation describes the process by which oxygen enters the blood in the lungs and becomes carried by hemoglobin and dissolved in plasma. This step is what allows oxygen to be delivered from the lungs to the bloodstream so it can reach tissues throughout the body. It’s a functional process, distinct from anatomy (the study of structures) and physiology in a broad sense (body functions) or tissue (a cellular organization). When clinicians talk about how well oxygen is getting into the blood, they’re referring to oxygenation, with measures like arterial oxygen content and saturation reflecting how well this step is occurring.
