During shock, blood flow is redirected away from organs that tolerate low flow toward more essential tissues. Which organ is most likely to receive reduced perfusion as part of this redistribution?

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

Answer: (C)

During shock, the body redirects blood flow toward the organs needed to sustain life, primarily the brain, heart, and lungs, by constricting peripheral vessels. This sympathetic response reduces blood flow to nonessential tissues to conserve oxygen for the critical organs. The skin is not vital for immediate survival, so its blood vessels constrict to a greater extent, leading to reduced perfusion. That’s why the skin is the organ most likely to become cool and pale as shock progresses.
