The primary organs of the respiratory system are the:
1. Lungs: These are the main organs responsible for breathing. They are divided into two lobes on the left side and three lobes on the right side.
2. Trachea: Also known as the windpipe, the trachea is a large tube that connects the larynx (voice box) to the bronchi.
3. Bronchioles: These are smaller branches of the bronchi that further divide into even smaller tubes called alveolar ducts.
4. Alveoli: These are the tiny air sacs located at the ends of the bronchioles. They are responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.
5. Diaphragm: This is a thin, dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays a crucial role in the process of breathing by contracting and relaxing to change the volume of the thoracic cavity.
6. Pharynx: The pharynx is a muscular tube that connects the nasal cavity to the larynx and esophagus. It serves as a passage for both air and food, but primarily functions in respiration.
Note: The heart is not considered a primary organ of the respiratory system. It is part of the circulatory system and pumps oxygenated blood received from the lungs to the rest of the body.
