Alveolar Anesthetic Gas Exchange in the Lungs - Medical Illustration, Human Anatomy Drawing
This medical illustration depicts the process of anesthetic gas exchange between an alveolus and a pulmonary capillary in the lungs. The curved gray structure on the right represents the alveolar wall. Yellow dots signify anesthesia molecules diffusing across the thin alveolar-capillary barrier into the blood. The blood vessel on the left contains red blood cells surrounded by plasma. Anesthesia molecules are shown entering the blood, which carries them to the brain.
