Describe the function of alveoli
WebAlveoli: Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. Bronchioles: Small branches of the bronchial tubes that lead to the alveoli. Capillaries: Blood vessels in the alveoli walls that move oxygen and carbon dioxide. Lung lobes: Sections of the lungs — three lobes in the right lung and two in the left lung. WebAlveoli are tiny air sacs in the lungs where gas is exchanged during breathing. Within the human lungs the alveoli provide an efficient exchange surface adapted for gas exchange.
