What occurs when an animal goes into shock?

• A. The peripheral circulation fails.
• B. The body temperature increases.
• C. A blood clot lodges in the brain.
• D. Nerve signals cannot respond.

Answer: (A)

In shock the key problem is that the circulatory system fails to deliver enough blood to the body’s tissues. That means peripheral circulation drops, so tissues and organs don’t get the oxygen and nutrients they need, leading to signs like cool, pale skin and a weak, rapid pulse as the body tries to compensate. This impaired perfusion is the defining feature of shock. The other scenarios aren’t the usual mechanism of shock: an increase in body temperature isn’t typical — shock often causes cooling or normal temperature due to poor perfusion; a clot lodging in the brain describes a stroke, a separate event; and nerve signals not responding isn’t the central issue—neuronal function can be affected by lack of blood flow, but the core problem in shock is insufficient circulation to tissues.
