Question

Below is a model of a crucial human body system. In 2 complete sentences, identify the body system, and explain how it interacts with the body system that is responsible for gas exchange with the external environment.

The model is of the circulatory system.

Answer 1

The circulatory system is responsible for transporting blood, nutrients, hormones, and oxygen throughout the body while also facilitating the removal of carbon dioxide and other waste products. It interacts closely with the respiratory system, which is responsible for gas exchange; oxygen is absorbed into the blood from the lungs and transported to body tissues, while carbon dioxide is carried back to the lungs to be exhaled.
