The circulatory system is best described as?

• A. System responsible for breathing
• B. An organ that pumps blood
• C. System that moves blood through the body
• D. Cleaning to reduce disease

Answer: (C)

Circulatory system moves blood through the body. It includes the heart, which acts as a pump, the blood vessels that form the highways for blood flow, and the blood itself that carries oxygen, nutrients, hormones, and waste products. This system that keeps blood circulating is essential for delivering what tissues need and for removing used materials like carbon dioxide. It works alongside the respiratory system to exchange gases, but its primary function is moving blood, not breathing or cleaning to prevent disease. So the best description is a system that moves blood through the body.
