Final answer:
Triage is the system used to categorize patient cases, allowing for efficient and effective allocation of care, especially during emergencies.
Step-by-step explanation:
Triage is a system that divides patient cases into categories so that care can be allocated effectively. Triage is crucial in medical settings, particularly in emergency departments or disaster scenarios, where healthcare professionals must quickly decide the priority of patients' treatments based on the severity of their conditions. This process ensures that those who are in the most critical need receive prompt and appropriate attention, promoting efficient use of limited medical resources.
