1 Respiratory System By: Gerald Williams & Najhee Duhon

2 Overview  The main job of the Respiratory system is to provide oxygen and remove carbon dioxide from the body.  Your respiratory system is made up of the organs in your body that help you to breathe.  Your body inhales air and then your respiratory system produces oxygen

3 Vocab  Alveoli-Tiny Air sacs in the lungs.  Larynx- The hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box.  Pharynx- The membrane-lined cavity behind the nose and mouth, connecting them to the esophagus.  Carbon Dioxide- a colorless, odorless gas produced by burning carbon and organic compounds and by respiration.

4 More Vocab  Pleura- Each of a pair of serous membranes lining the thorax and enveloping the lungs in humans.  Thorax- The area between the neck and the abdomen, including the cavity enclosed by the ribs, breastbone, and dorsal vertebrae, and containing the chief organs of circulation and respiration.

5 Parts Of Respiratory System Lungs:  Main organs of the respiratory system.  Oxygen is taken into the body and carbon dioxide is breathed out.  Red blood cells are responsible for picking up the oxygen in the lungs and carrying the oxygen to all the body cells that need it.

6 Lungs Continued  Red blood cells drop off the oxygen to the body cells, then pick up the carbon dioxide.  The red blood cells transport the carbon dioxide back to the lungs and we breathe it out when we exhale.

7 Parts of Respiratory System  Trachea: Commonly known as the windpipe the trachea is essentially The trachea is a tunnel that connects your pharynx and larynx to your lungs, it allows your to pass air through your body.  Also connected to the inferior thyroid artery.  Around centimeters long  5 ring shaped divots along the trachea that allow the air to pass through with ease and no complications.

8 Parts of Respiratory System  Bronchi: Two air tubes that branch off of the trachea and carry air directly into the lungs.  There is a right bronchus and a left bronchus and these bronchi branch into smaller secondary and tertiary bronchi which branch into smaller tubes, known as bronchioles.  The right main bronchus is wider, shorter, and more vertical than the left main bronchus.  Unlike the lungs and the Trachea the bronchi has no involvement with carbon dioxide or any kind of gases.

9 Bronchi continued  Often asthma comes from an odd or irregular structure or build of the bronchi which refrains the bronchi from carrying the air to the lungs therefore causing a difficult breathing process.  Bronchitis also comes from complications with the Bronchi. This comes from inflammation of lining of the bronchi tubes which pass the air through your respiratory system.

10 Parts of Respiratory System  Diaphragm: A dome-shaped muscle at the bottom of the lungs called the diaphragm is what the whole breathing process begins with.  When you breathe in, the diaphragm contracts.  When it contracts it flattens out and pulls downward. This movement enlarges the space that the lungs are in.  When you breathe out, the diaphragm expands reducing the amount of space for the lungs and forcing air out.

11 Diaphragm Continued  The diaphragm separates the thoracic cavity containing the heart and lungs, from the abdominal cavity  The diaphragm is located near the bottom of the lungs and extends across the bottom of the rib cage.
