why are bronchioles and alveoli considered the main parts of the lungs that deliver oxygen to the blood?

Answers

Answered by mansi2847

The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood. After absorbing oxygen, the blood leaves the lungs and is carried to the heart. The blood then is pumped through your body to provide oxygen to the cells of your tissues and organs.
