Body Systems Interaction Practice Test

Use the organism model: A bird is shown with Respiratory System (air sacs/lungs) and Muscular System (flight muscles). The Circulatory System is also shown between them. Arrows show oxygen moving from the Respiratory System to the Circulatory System and then to the Muscular System. A note says: “Flight function depends on interaction among systems.”

Which statement about system interaction is supported by the model?

Use the organism model: A dog is shown with Respiratory System (lungs), Circulatory System (heart/blood vessels), and Excretory System (kidneys). Arrows show oxygen moving from lungs to blood, “wastes” moving from body cells into blood, and wastes moving from blood to kidneys. The model states: “Normal body function depends on system interaction.”
