Where are the alveoli located in the human body?

Human bodyRespiratory system

Quick Answer

Alveoli are located at the ends of the smallest airways in the lungs. They are the tiny air sacs where gas exchange happens.

The Full Story

Alveoli are found deep in the lungs, clustered at the ends of the bronchioles. Their thin walls and huge surface area allow oxygen to enter the blood and carbon dioxide to leave it. An adult human has roughly 300 million alveoli, creating a large exchange surface. This structure is essential for efficient breathing and oxygen delivery to tissues.
