Parts of the lower respiratory tract
Trachea-found at the end end of the larynx; has pipelike structure that lets the inhaled air travel the airways to the lungs; branches into 2 bronchi
Bronchi- the left and right bronchi enable the air to enter the left and right lungs, respectively; bronchioles are the smallest branches
Alveoli- found at the end of each bronchiole; resembles an air sac; exchange oxygen and carbon dioxide during breathing; it is where the gas exchange occurs through diffusion
Lungs- located on either side of the chest and protected by the rib cage; the right lung has three lobes while the left has two lobes
