Questions: Match the body system to its main function(s). Integumentary System [Choose] Skeletal System [Choose] Muscular System [Choose] Nervous System [Choose] Endocrine System [Choose] Cardiovascular System [Choose ] Lymphatic System [Choose ] Respiratory System [Choose ]

To match each body system to its main function(s), we need to understand the primary role of each system in the human body. Here is the correct matching:

1. Integumentary System

   • Main Function: Protects the body, regulates temperature, and provides sensory information.
   • Explanation: The integumentary system includes the skin, hair, and nails, which serve as a barrier to protect the body from the outside environment, help regulate body temperature, and allow for sensory perception.

2. Skeletal System

   • Main Function: Provides structure, supports and protects organs, and facilitates movement.
   • Explanation: The skeletal system consists of bones and joints, which provide the framework for the body, protect internal organs, and work with muscles to enable movement.

3. Muscular System

   • Main Function: Facilitates movement, maintains posture, and produces heat.
   • Explanation: The muscular system includes all the muscles in the body, which contract to produce movement, help maintain posture, and generate heat as a byproduct of muscle activity.

4. Nervous System

   • Main Function: Controls and coordinates body activities by transmitting signals.
   • Explanation: The nervous system, composed of the brain, spinal cord, and nerves, is responsible for receiving sensory input, processing information, and sending out commands to the body.

5. Endocrine System

   • Main Function: Regulates body functions through hormones.
   • Explanation: The endocrine system consists of glands that secrete hormones into the bloodstream, which regulate processes such as growth, metabolism, and reproduction.

6. Cardiovascular System

   • Main Function: Transports nutrients, gases, and wastes; regulates temperature and fluid balance.
   • Explanation: The cardiovascular system, including the heart and blood vessels, circulates blood throughout the body, delivering oxygen and nutrients to cells and removing waste products.

7. Lymphatic System

   • Main Function: Defends against infection and disease, returns tissue fluids to the bloodstream.
   • Explanation: The lymphatic system includes lymph nodes and vessels, which help protect the body from infection and maintain fluid balance by returning excess tissue fluid to the bloodstream.

8. Respiratory System

   • Main Function: Facilitates gas exchange (oxygen and carbon dioxide) between the body and the environment.
   • Explanation: The respiratory system, including the lungs and airways, is responsible for taking in oxygen and expelling carbon dioxide, which is essential for cellular respiration and energy production.

In summary, each body system has a distinct primary function that contributes to the overall health and operation of the human body.
