Explanation:
The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, also known as fossae.
The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and larynx – the tubes going down to the stomach and the lungs. It is found in vertebrates and invertebrates, though its structure varies across species
The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi.
The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi.
The larynx (/ˈlærɪŋks/), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The larynx houses the vocal folds, and manipulates pitch and volume, which is essential for phonation.
The vocal cords (also called vocal folds) are two bands of smooth muscle tissue found in the larynx (voice box). The vocal cords vibrate and air passes through the cords from the lungs to produce the sound of your voice.
Answer:
1. It is the cavity inside our nose, which is lined with mucus to maintain the moisture in our nose.
2. The hollow tube inside the neck that starts behind the nose and ends at the top of the trachea and oesophagus is called pharynx.
3. The trachea is a long tube if about 4 inches that begins just under the larynx (voice box) and runs down behind the breastbone.
4. The area of the throat containing the vocal cords and used for breathing, swallowing, and talking is called larynx.
5. The thin bands of muscle in the back of your throat that move to produce the voice are called the vocal cords.
