Which term describes the delivery of oxygen-rich blood to tissues?

The correct term that describes the delivery of oxygen-rich blood to tissues is perfusion. This process is critical for maintaining the health and function of organs and tissues, as it ensures that they receive the necessary oxygen and nutrients that blood carries. Effective perfusion relies on adequate blood flow and is essential in many physiological and medical contexts, including response to trauma and managing various health conditions.

Oxygenation refers specifically to the process of adding oxygen to the blood, primarily in the lungs, rather than the distribution of that oxygen-rich blood to tissues. Circulation describes the overall movement of blood throughout the body but does not specifically convey the idea of delivering oxygenated blood to tissues. Resuscitation pertains to the methods used to restore life or consciousness, particularly in cases of cardiac arrest or respiratory failure, which may involve restoring perfusion among other processes but does not specifically define the delivery of oxygen-rich blood.
