1. Respiratory System Chapter # 7 By: Precious Blanton

2. Introduction: The human body is an amazing and complex machine. Each system allows you to be able to do so many things read, breathe, see, walk, hear, smell, think, feel, taste, and so much more.Also, the respiratory system includes the upper respiratory segments also called the respiratory passages and the lower respiratory parts made of the lower conducting airways and the lungs. A brief review of the normal anatomy and histology of the different components of the respiratory system is important in order to understand the basic pathologies of the organs.

3. Nasal cavity The nasal cavities conditions the air to be received by the areas of the respiratory tract and noses. Owing to the large surface area provided by the conchae, the air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature. In addition, the air is humidified, and dust and other particulate matter is removed by vibrissae, short, thick hairs, present in the vestibule. The cilia of the respiratory epithelium move the particulate matter towards the pharynx where it is digested.

5. Larynx- breathing and speech

9. Your lungs are in your chest, and they are so large that they take up most of the space in there. You have two lungs, but they aren't the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your heart.

11. The average pair of humanlungs can hold about 6 liters of air, but only a small amount of this capacity is used during normal breathing.

12. Breathing mechanism in mammals is called "tidal breathing". Tidal breathing means that air goes into the lungs the same way that it comes out.

15. Diaphragm- which is the muscle separating the abdomen from the thoracic cavity. The diaphragm it moves downward. Also, air then flows into the lungs, inhalation, to equalize the pressure.

17. Eat healthy

18. Get a annual doctor checkups.

20. Being around people who smoke.

21. Being around thick polluted air and dusty.
