What parts of your body make up the respiratory system?
The main organs of the human respiratory system are:
- The nose
- The pharynx (throat)
- The larynx (voice box)
- The trachea (windpipe)
- The bronchi (the two large branches of the trachea that lead to the lungs)
- The bronchioles (the smaller branches of the bronchi)
- The alveoli (tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged)
Other structures that contribute to the respiratory system include:
- The diaphragm( the muscle that separates the chest from the abdomen and plays a major role in breathing)
- The intercostal muscles( the muscles between the ribs that also assist in breathing)
- The cartilaginous rings that support the trachea and bronchi
- The mucus-producing glands in the nose, throat, and lungs
