The respiratory system is a collection of organs and tissues that aid in breathing. This system assists our bodies in absorbing oxygen from the air so that our organs can function properly. It also removes waste gases from our blood, such as carbon dioxide.
1. Nasal Cavity – The nasal cavity is a wide, air-filled region in the centre of the face above and behind the nose. The nasal septum splits the cavity into two fossae, or cavities. One of the two nostrils continues into each hollow. The mucociliary system protects the respiratory tract by humidifying, warming, filtering, and acting as a conduit for inhaled air in the nasal cavity. The olfactory receptors are also found in the nasal cavity.
2. Larynx – The larynx, often known as the voice box or glottis, is the airway that connects the pharynx above and the trachea. It is found between the fourth and sixth vertebral levels. The sublarynx, larynx, and supralarynx are the three sections of the larynx. It is made up of nine cartilages that are joined by muscles and ligaments. The larynx is an important part of human speech. The vocal cords tighten together and vibrate as air exhaled from the lungs passes between them during sound production. The false vocal cords do not produce sound, but they do assist in closing down the larynx when food is swallowed.
3. Lungs – Lungs are tissue sacks found just beneath the rib cage and above the diaphragm. They play a key role in the body’s waste management and respiratory system. The lungs function similarly to bellows. They pull air into the body when they expand. When they compress, they release carbon dioxide, a waste gas produced by living things. However, there are no muscles in the lungs to pump air in and out. The lungs are primarily pumped by the diaphragm and rib cage.
