2 The Respiratory System

3 Functions of the Respiratory System 1.Provides gas exchange between air and circulating blood 2.Produces sounds-speaking, singing 3.Participates in olfactory sense

4 Components of the Respiratory System

5 Anatomy of the Epiglottis Epiglottis- flap that covers the trachea

6 Anatomy of the Larynx

7 Larynx The vocal cords are made of two bands of muscle. When we talk, the vocal cords tighten up and move closer together. Air from the lungs is forced between them and makes them vibrate, producing the sound of our voice. The tongue, lips, and teeth form this sound into words.

9 Anatomy of the Trachea

10 The Trachea Also called the windpipe Branches into right and left bronchi

11 Inside the Lungs Bronchioles- air branches in the lungs

12 Inside the Lungs Alveoli- air sacs in the lungs that exchange O 2 with CO 2

14 Anatomy of the Diaphragm Diaphragm- The main muscle that contracts and relaxes to allow breathing

15 Breathing with the Diaphragm INHALING EXHALING

16 Common Problems with the Respiratory System

17 Pneumonia Pneumonia- infection of the lungs that results in an inflammation of the small air spaces of the lung. Pneumonia reduces the lungs' ability to receive and distribute oxygen. It can be mild and easily cured with antibiotics and rest, or it can be severe and require hospitalization.

18 Pneumonia

19 Bronchitis Bronchitis is an inflammation of the bronchiole tubes. It can be caused by bacteria or viruses.

20 Emphysema Emphysema The disease in which the alveoli lose their elasticity, thus making it hard to breathe.
