Question

functions: a group of organs that work together to transfer oxygen from the atmosphere to the blood and transfer carbon dioxide from the blood to the atmosphere. choose an answer 1 nervous system 2 respiratory system 3 skeletal system 4 cardiovascular system

Explanation:

The respiratory system's main function is gas exchange. It takes in oxygen from the atmosphere and transfers it to the blood while removing carbon dioxide from the blood and expelling it to the atmosphere. The trachea, bronchi, and lungs (as shown in the diagram) are key organs of this system. The nervous system controls body functions through nerve signals, the skeletal system provides structural support, and the cardiovascular system (heart and blood vessels) circulates blood. Since the description matches the respiratory system's role, it is the correct choice.

Answer:

2 Respiratory System
