Choose a major body system in a human. In 3-5 sentences, explain the role of this system in the overall function of the organism and describe how it interacts with at least one other body system to maintain homeostasis.(4 points)

Answer 1

The circulatory system plays a crucial role in maintaining the overall function of the human body by transporting oxygen, nutrients, hormones, and waste products to and from cells. It works closely with the respiratory system, which is responsible for bringing oxygen into the body and removing carbon dioxide. The oxygen absorbed in the lungs is carried by the blood, delivered to cells for metabolism, while carbon dioxide is picked up from the cells and transported back to the lungs for exhalation. This interaction helps maintain homeostasis by ensuring that cells receive the necessary oxygen for energy production and that waste products are efficiently removed.
