Which system plays a major role in the transport of nutrients and oxygen to cells?

• A. Nervous
• B. Skeletal
• C. Circulatory
• D. Muscular

Answer: (C)

The circulatory system is crucial for transporting nutrients and oxygen throughout the body. It consists of the heart, blood vessels, and blood, which work together to ensure that essential substances are delivered to cells while also carrying waste products away for elimination. Oxygen is absorbed into the bloodstream through the lungs and quickly distributed by red blood cells to all body tissues. Simultaneously, nutrients absorbed from the digestive system enter the bloodstream and are transported to cells where they are utilized for energy, growth, and repair. This efficient delivery system supports cellular metabolism and overall bodily function. In contrast, other systems such as the nervous, skeletal, and muscular systems have different primary roles. The nervous system focuses on transmitting signals between different parts of the body, the skeletal system provides structure and support, and the muscular system is involved in movement. While these systems are interconnected and rely on the circulatory system for health and function, it is the circulatory system that directly facilitates the transport of vital nutrients and oxygen to cells.
