Which organ pumps blood around the body?

**The reasoning** The **heart** is the body's natural pump. Think of it like a water pump in your compound — it creates pressure to push water through the pipes. Similarly, your heart contracts (squeezes) rhythmically to force blood through your entire circulatory system, delivering oxygen and nutrients to every cell from your brain to your toes. This pumping action happens about 70-100 times per minute, non-stop, throughout your life. The heart has four chambers that work together to receive blood and push it out efficiently. **Why the wrong options tempt you** - **Liver (A)** — Processes nutrients and filters toxins from blood, but doesn't pump it - **Lungs (B)** — Add oxygen to blood and remove carbon dioxide, but they don't create the pressure to move blood around - **Kidney (D)** — Filters waste from blood to make urine, but relies on the heart to bring blood to it All these organs work *with* blood, but only the heart actively **pumps** it. **Quick takeaway** The heart is your body's engine room — the only organ designed to pump blood continuously through your entire body.
