Which description BEST matches the system with the function? The muscular system is responsible for movement. The nervous system allows you to respond to stimuli. The respiratory system allows you to take in oxygen. The urinary system allows you to eliminate solid waste. The digestive system is responsible for absorption of valuable nutrients. The circulatory system transports important molecules. The respiratory system eliminates waste. The endocrine system helps you fight off infection. The skeletal system protects the body. The integumentary system allows you to reproduce. The immune system is responsible transporting valuable nutrients. The digestive system eliminates liquid waste.

The statement "The urinary system allows you to eliminate solid waste" does not correctly match the typical functions of the human body systems. The correct matches for the systems mentioned would be:

- The urinary system is responsible for the elimination of liquid waste (urine), not solid waste. Solid waste is eliminated through the digestive system. - The digestive system is responsible for the absorption of valuable nutrients and for the elimination of solid waste. - The respiratory system allows you to take in oxygen and eliminate carbon dioxide, which is a gaseous waste product of metabolism. - The circulatory system transports important molecules such as oxygen, carbon dioxide, nutrients, and waste products throughout the body. - The muscular system is responsible for movement. - The nervous system allows you to respond to stimuli. - The endocrine system produces hormones that regulate various functions in the body but is not directly responsible for fighting off infection; that role belongs to the immune system. - The skeletal system protects the body's internal organs and provides support for the body. - The integumentary system, which includes the skin, hair, nails, and associated glands, protects the body, helps regulate body temperature, and can be involved in sensory reception but is not responsible for reproduction. - The immune system is responsible for fighting off infection, recognizing and responding to pathogens, and helping in the healing process.

Extra: Understanding the different body systems and their functions is fundamental for students studying biology or health-related fields. Here's a brief overview of the main functions of the body systems mentioned:

- Muscular System: It's made up of muscles that allow you to move, maintain posture, and produce heat through contraction. - Nervous System: It includes the brain, spinal cord, and nerves. This system sends and receives messages to and from all parts of the body, coordinating actions and reactions to the environment. - Respiratory System: It comprises the lungs and airways, enabling oxygen intake and carbon dioxide release during the process of breathing. - Urinary System: It includes the kidneys, ureters, bladder, and urethra, which together filter blood and remove liquid waste (urine) from the body. - Digestive System: This system breaks down food into nutrients that the body can absorb and use for energy, growth, and cell repair, and also expels solid wastes. - Circulatory System: Consisting of the heart and blood vessels, this system circulates blood throughout the body, carrying nutrients, oxygen, and waste products to and from cells. - Endocrine System: It's a collection of glands that secrete hormones, which regulate growth, metabolism, and sexual development and function. - Skeletal System: The bones and joints form the framework of the body, protect internal organs, and along with muscles, facilitate movement. - Integumentary System: This includes the skin, hair, nails, and exocrine glands. It protects the body, helps regulate body temperature, and provides sensory information. - Immune System: Comprised of various cells, tissues, and organs including lymph nodes and white blood cells, it defends the body against infectious organisms and other invaders.
