Question

complex organisms, such as humans, are made up of organ systems that work together. read about one way organ systems work together to carry out essential functions in humans. when a person needs to move their body, their brain, which is part of the nervous system, sends signals to muscles in the muscular system. these muscles contract, which makes a body part move. which of these examples also support the claim that different organ systems work together? select all that apply. the digestive system breaks down food and absorbs nutrients that are used by the body’s cells. as cells use nutrients, they create waste that the excretory system moves out of the body through urine. the circulatory system contains blood vessels, such as arteries and veins. arteries move blood away from the heart, and veins bring the blood back to the heart. the respiratory system brings oxygen into the lungs. the lungs send oxygen to the blood so the circulatory system can deliver this oxygen to all of the cells in the body.

Explanation:

• The first correct option shows the digestive system (supplying nutrients) and excretory system (removing waste) working together to support cell function.
• The second correct option shows the respiratory system (taking in oxygen) and circulatory system (transporting oxygen) collaborating to deliver oxygen to body cells.
• The incorrect option only describes the structure and function of the circulatory system alone, with no interaction with another organ system.

Answer:

1. The digestive system breaks down food and absorbs nutrients that are used by the body's cells. As cells use nutrients, they create waste that the excretory system moves out of the body through urine.
2. The respiratory system brings oxygen into the lungs. The lungs send oxygen to the blood so the circulatory system can deliver this oxygen to all of the cells in the body.
