Respiratory System Song

The video explains the process of breathing and gas exchange in the human body. It describes how oxygen enters through the mouth or nose, travels past the pharynx, larynx, and trachea, and reaches the lungs via the bronchi. In the alveoli, oxygen diffuses into the blood, while carbon dioxide is expelled. The diaphragm and intercostal muscles play a crucial role in facilitating breathing by expanding and contracting the lungs. The video concludes with a recap of these processes.
