Organ System and its Components

Organ systems are a group of organs that work together to perform a specific function in the body. Each organ system has its own unique set of organs that work together to maintain the body's homeostasis. Let's discuss the components of the organ system mentioned in the given question.

Central Nervous System

The central nervous system (CNS) consists of the brain and the spinal cord. It is responsible for receiving and processing sensory information, coordinating motor function, and regulating the body's response to various stimuli.

Peripheral Nervous System

The peripheral nervous system (PNS) consists of nerves that extend from the brain and spinal cord to the rest of the body. The PNS is responsible for transmitting sensory information to the CNS and carrying motor commands from the CNS to the muscles and glands.

Lungs

The lungs are a part of the respiratory system, which is responsible for exchanging gases between the body and the environment. The lungs take in oxygen and release carbon dioxide through a process called respiration.

Conclusion

Based on the above discussion, we can see that the lungs do not belong to the same organ system as the brain, spinal cord, and nerves. The lungs belong to the respiratory system, while the brain, spinal cord, and nerves belong to the nervous system. Therefore, option D (lungs) is the correct answer.
