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 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 digestive system breaks down food and absorbs nutrients that are used by the bodys cells. as cells use nutrients, they create waste that the excretory system moves out of the body through urine. 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 option only describes the circulatory system's components and their functions within that single system. The second option shows the digestive system breaking down food and the excretory system handling waste created by cells using nutrients from digestion - two systems working together. The third option shows the respiratory system getting oxygen into the lungs and the circulatory system delivering that oxygen - two systems working together.

Answer:

The second option (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.) and the third option (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.)
