Explanation:

Organ systems are groups of organs that work together to perform a certain function in the body. The human body consists of eleven organ systems. Four of them are included in the question you were given.

The respiratory system is the system of organs that allow us to breathe. It includes the airways, lungs, and blood vessels.

The nervous system is the organ system that coordinates our behavior and transmits signals between different parts of our body. It consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.

The muscular system is the organ system that permits movement of the body, maintains posture, and circulates blood throughout the body. It consists of skeletal, smooth, and cardiac muscles.

The circulatory system is the organ system that carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. It consists of the blood, blood vessels, and heart.

Based on this information, we can conclude what function belongs to which organ system.
