Which organ pumps blood through the body, is monitored by an EKG, and may be stabilized with a pacemaker or CPR if it stops functioning?

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

Answer: (A)

The heart is the organ that pumps blood through the body. An EKG, or electrocardiogram, records the heart’s electrical activity, showing its rhythm and timing. If the heart beats too slowly, too quickly, or irregularly, a pacemaker can help by delivering electrical impulses to keep it beating regularly. If the heart stops altogether, CPR (cardiopulmonary resuscitation) helps maintain blood flow and oxygen delivery until further medical help can restore the heartbeat. The other options don’t fit because the lungs, liver, and brain don’t perform the pumping action the heart does, and they aren’t stabilized by a pacemaker or CPR in the same direct way.
