Hello, I am going to do a blog post about the respiratory system. We currently learned about the respiratory system in my foundations of kinesiology class with Dr. Pontifex. It was really interesting to me because it is really important to the anatomy of the body. I will be talking about the respiratory cycle and everything that it contributes to our health.
Some of the major things that the respiratory system is involved in is the heating and cooling of the body, filtering inspired air to protect against microorganisms, modulates the circulating levels of carbon dioxide, and the movement of air past vocal folds that make sound and speech. All of these are really important to our health, without them we wouldn't be in control of our body temperature or even the protection of microorganisms.
3 stages of the respiratory cycle are pulmonary ventilation, external respiration, and internal respiration. Pulmonary ventilation is the exchange of gases between lungs and external enviroment. External respiration is the exchange of gases between the lungs and the blood stream. Lastly, the internal respiration is functioned in the exchange of gases between the blood stream and bodily tissues. All of the structures that make up the airway and allow us to breath is primarily what the respiratory system is all about.
The respiratory system can be divided into two separate zones. The conduction zone that consists of all the respiratory passageways, and the respiratory zone that is home to where gases are exchanged. All the major components that are involved in these two zones are the nasal cavity, lungs, pharynx, oral cavity, larynx, trachea, bronchi, pleura, and the alveoli. Nasal cavity and oral cavity mainly consists of the passageway of respiration through the nose and the mouth. The pharynx is resembled as the throat that aides in the swallowing of air. The larynx represents only a small section of the respiratory tract. It connects the laryngopharynx to the trachea. The lungs are paired, right and left. The bronchi is the lower end of the trachea. Pleura are where the lungs are enclosed by membranes. Lastly, the alveoli are small inflatable sacs at the end of bronchioles.

Overall, this was primarily the main points that I learned about the respiratory system in class. The respiratory system is very complex because of all the zones, stages, and components that make it all up. I really enjoyed learning this in class because I find it really interesting that all the breathing that we do every day goes through all of these processes that we are so unaware of.
