The heart is an () organ in the body.

• A. Internal
• B. External
• C. Peripheral
• D. Central

Answer: (A)

The main idea here is where an organ sits in the body—inside versus on the surface. The heart is inside the body, tucked in the chest within the thoracic cavity, so it’s an internal organ. It operates as part of the body's internal systems to pump blood through the circulatory system. If we described it as external, it would imply it’s on the surface or outside the body, which isn’t true. Terms like central or peripheral aren’t the standard way to classify an organ’s location in the body; they’re less precise for this purpose. So internal is the most accurate description.
