Which organ system is primarily responsible for transporting nutrients, gases, and wastes throughout the fetal pig's body as seen in a labeled diagram?

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

Answer: (A)

Verified step by step guidance

1. Step 1: Begin by identifying the primary function of each organ system listed in the question. For example, the circulatory system is responsible for transporting nutrients, gases, and wastes throughout the body.
2. Step 2: Recall that the circulatory system includes the heart, blood vessels, and blood, which work together to distribute oxygen, nutrients, and remove waste products.
3. Step 3: Compare the functions of the other systems listed. The nervous system is responsible for transmitting signals and coordinating bodily functions, the digestive system processes food and absorbs nutrients, and the respiratory system facilitates gas exchange (oxygen and carbon dioxide).
4. Step 4: Relate the function of transporting nutrients, gases, and wastes to the circulatory system, as it is the system that directly performs this role through blood circulation.
5. Step 5: Confirm your understanding by reviewing a labeled diagram of the fetal pig's anatomy, noting the heart, arteries, veins, and their connections to other systems, which highlight the circulatory system's role in transport.
