Problem 5

Background and context

The respiratory system consists of two parts such as air passageway and lungs. Further, this air passageway made up of nostrils, nasal cavities, pharynx, larynx, trachea, and bronchi and bronchioles are present in the lungs. The air enters the body through the nostrils to the nose. This nostril has two nasal cavities with hair and mucus. In this nasal cavity, airs are filtered and maintained their temperature according to body temperature. The next air passes through the pharynx and removed germs here, and further air moves to the larynx, then the trachea. In the trachea again, the air is filtered by mucus. Finally, two bronchi are made of the extended form of the trachea, and further air pass by each lead to the lungs.
