In the context of human anatomy, which organ system is primarily responsible for transporting nutrients, gases, and waste products throughout the body?

• A. Nervous system
• B. Respiratory system
• C. Digestive system
• D. Circulatory system

Answer: (D)

Verified step by step guidance

1. Begin by identifying the primary function of each organ system mentioned in the problem. The nervous system is responsible for transmitting signals throughout the body, the respiratory system is involved in gas exchange, and the digestive system is responsible for breaking down food and absorbing nutrients.
2. Consider the main function of the circulatory system. It is responsible for transporting blood throughout the body, which carries nutrients, gases (such as oxygen and carbon dioxide), and waste products.
3. Understand that the circulatory system includes the heart, blood vessels, and blood. The heart pumps blood through the vessels, allowing for the distribution of essential substances to cells and the removal of waste products.
4. Recognize that the circulatory system works closely with other systems, such as the respiratory system, to facilitate the exchange of gases. Oxygen is transported from the lungs to tissues, and carbon dioxide is carried from tissues back to the lungs for exhalation.
5. Conclude that the circulatory system is the organ system primarily responsible for transporting nutrients, gases, and waste products throughout the body, as it integrates with other systems to maintain homeostasis.
