Larynx - Here, muscular bands are arranged as a V-shaped structure. These are the vocal cords or the vocal folds and are the reason the larynx is often called the sound box or the voice box.
Trachea (or windpipe) - A wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs.
Alveoli - Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs which are called alveoli.
Epiglottis - A flap that is made of elastic cartilage tissue covered with a mucous membrane and is attached to the entrance of the larynx.
