Pulmonary gas exchange occurs only in the lungs, specifically in the alveoli, where oxygen diffuses from the air into the bloodstream and carbon dioxide diffuses from the bloodstream into the air. Systemic gas exchange occurs throughout the body, specifically at the capillaries, where oxygen and nutrients are released from the bloodstream into the tissues, and carbon dioxide and waste products are taken up from the tissues into the bloodstream. Therefore, pulmonary gas exchange is limited to the lungs while systemic gas exchange occurs throughout the body.
