Histology Art (MT 30 – J) 3 years, 8 months ago The organs and other components of the body that are involved in breathing and exchanging oxygen and carbon dioxide are referred to as the respiratory system. This system includes the Trachea (windpipe), Pharynx (throat) and Larynx (voice box).
The trachea is an important component of the respiratory system. The larynx (voice box) and the bronchi are connected by the trachea. It is made up of cartilage rings that are surrounded by mucus-producing cells. Mucus keeps allergens, dust particles, and other detritus out of the lungs.
Both respiratory and digestive processes are served by the pharynx chamber. It is a cone-shaped pathway from the oral and nasal cavities in the head, to the esophagus and larynx. The circular muscles assist drive food to the esophagus and prevent air from being ingested, while the longitudinal muscles elevate the pharynx walls when swallowing.
The larynx is a hollow, tubular structure attached to the top of the throat (trachea), through which air flows on its route to the lungs. The larynx is also responsible for producing vocal sounds and preventing food and other foreign material from entering the lower respiratory passages. It has an exterior skeleton of cartilage plates that protects the structure from collapsing. Membranes and muscle fibers bind the plates together.References:
