Alveolar Artery - English Definition & Meaning

Definition

An alveolar artery is a small blood vessel that supplies blood to the alveoli in the lungs. Alveoli are tiny air sacs where oxygen and carbon dioxide exchange occurs. These arteries branch off from the pulmonary artery, ensuring each alveolus receives adequate blood flow for gas exchange. Think of them as the delivery trucks bringing oxygen to the smallest towns. Proper function is crucial for efficient respiration and overall health. 🫁

Etymology

"Alveolar" comes from the Latin word "alveolus," meaning "small cavity" or "air sac." "Artery," as explained before, comes from Latin/Greek roots referring to blood vessels. Therefore, an alveolar artery is a blood vessel specifically serving the air sacs (alveoli) in the lungs.
