Which organ can tolerate inadequate perfusion for two to three hours?

• A. A. Heart.
• B. B. Brain.
• C. C. Skeletal muscle.
• D. D. Kidneys.

Answer: (C)

Skeletal muscle is known to be more tolerant of inadequate perfusion compared to other vital organs like the heart, brain, and kidneys. This is primarily due to its ability to efficiently utilize anaerobic metabolism during times of reduced blood flow. When perfusion is compromised, skeletal muscle can temporarily survive on less oxygen, allowing it to cope with the deficit for a period of two to three hours. In contrast, organs such as the heart and brain are highly dependent on a continuous supply of oxygenated blood to function properly, and they suffer damage much more quickly when perfusion drops. The brain, in particular, can begin to sustain irreversible damage within just a few minutes of inadequate blood flow. The kidneys also require a consistent blood supply to filter waste from the bloodstream efficiently, and while they can withstand some reduction in blood flow, their tolerance is not as extended as that of skeletal muscle.
