Coma is a state associated with which organ?

• A. Brain
• B. Heart
• C. Lungs
• D. Liver

Answer: (A)

Coma reflects severe dysfunction of the brain, the organ that controls consciousness, wakefulness, and responsiveness. When brain activity is dramatically reduced by injury, stroke, infection, metabolic problems, or toxins, a person cannot be aroused or respond to stimuli, which is characteristic of coma. The heart, lungs, and liver are essential for sustaining life, but coma itself points to brain impairment; problems in those organs can affect the brain indirectly by reducing oxygen or blood flow, yet they aren’t the organ in which coma originates.
