What Role Do the Alveoli Play in Gas Exchange?

Alveoli are often emphasized because they’re the site of gas exchange. The answer key

explains that oxygen diffuses through the thin walls of alveoli into the surrounding

capillaries, where it binds to hemoglobin in red blood cells. Simultaneously, carbon dioxide

diffuses from the blood into the alveoli to be exhaled. This process is essential for

maintaining homeostasis and proper oxygen levels in the body.

Why Is the Respiratory System Linked to the Circulatory System?

The answer key clarifies the interdependence between these two systems. It points out

that while the respiratory system brings oxygen into the body, the circulatory system

transports it to cells and removes waste gases. This collaboration ensures efficient

delivery of oxygen and removal of carbon dioxide, which is vital for cellular metabolism.
