Respiratory system

1. By Joe Thompson, Raquel Zollo, Eric Bolling Respiratory system

2. Introduction to the respiratory system • The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. • The organs of the respiratory system are things like the windpipe, many parts of the throat, lungs, and tongue.

3. Major functions of the respiratory system • The respiratory system is responsible for: • Gas exchanges • Regulation of blood ph • Voice production • Sense of smell • Providing protection form micro organisms

4. The nasal passage • The nasal passage is a channel of airflow through the nose • The nasal passage has short hairs that prevent things like dust, bacteria, and other particles from being inhaled into the lungs • The “organs” of smell are made up of patches of tissue called olfactory membranes

6. The Windpipe • The windpipe/trachea is a tube like portion of the respiratory system that connects the larynx (voicebox) to the bronchial parts of the lungs. • When humans take in breaths, the air goes through the larynx, down the trachea, and into the lungs. • When you exhale it goes the opposite direction • The esophagus is the tube that carries food from the mouth to the stomach

8. Parts of the throat • The nasopharynx is the part of the throat that connects the nasal cavity to the top of the throat • The oropharnyx is the part of the windpipe that connects the throat to the mouth • The larnygopharynx is the part of the throat that connects the windpipe to the esophagus.

10. The lungs • The parts of the lungs consist of the lobes, the 2 bronchus’s, and the diaphragm • The lungs are divided into two parts called the lobes, the right lobe has 3 of the 3 lobes in it, superior lobes, middle lobes, and inferior lobes • The left lobe has only 2 of the 3 lobes, the superior and inferior lobes.

11. Lungs continued… the bronchus • The trachea divides into a right and left main bronchus. Each major bronchus then subdivides into smaller airway passages referred to as bronchi. As the airway passages make their way out to the lung tissue, the passages become smaller and are referred to as bronchioles. Eventually the bronchioles terminate into small collections of air sacs known as alveoli, which is where the actual exchange of CO2 and Oxygen occur.

12. Lungs continued… the diaphragm • The diaphragm is the part fo the respiratory system that provides a shape and protection of the lungs • It is a dome shaped structure that is a barrier between the lungs and other organs and tissue

14. The tongue • The tongue is a muscular organ in the mouth. The tongue is covered with moist, pink tissue called mucosa. Tiny bumps called papillae give the tongue its rough texture. Thousands of taste buds cover the surfaces of the papillae. Taste buds are collections of nerve-like cells that connect to nerves running into the brain. Which then send directions to other organs.

15. The Breathing process • You breathe with the help of your diaphragm (which is a dome-shaped muscle under your rib cage) and other muscles in your chest and abdomen. These muscles will literally change the space and pressure inside your body cavity to accommodate your breathing. When your diaphragm pulls down, it is making room for the lungs to expand. The lungs get bigger with air and pushes the diaphragm down. The diaphragm also lowers the air pressure.

16. The respiration process • respiration is defined as the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction

18. Correlation to other organs in the body • Circulatory system- the lungs are where oxygen is picked up by the blood and transported through the body. • The nervous system- the nervous system controls the breathing rate of the respiratory system • The immune system- most of the respiratory system is lined with mucous associated lymphoid tissue that is very important to the nervous system because it produces immune cells

19. Asthma • Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. • Asthma causes periods of wheezing, chest tightning, shortness of breath, and coughing

20. Diagnosing Asthma • Go to your doctor and talk to them about your symptoms, and health records • Your doctor should then examine your nose throat, airways, and skin for rashes. • Then your doctor should listen to your breathing

22. Treating Asthma • You should make sure you keep away from allergens, respiratory infections, and be cautious in cold weather • The best treatment for asthma and heavy breathing is inhaling corticosteroids.

23. How to tell if you have it. • If you feel any of the symptoms below than tell your doctor. • Chronic (regular) cough. • Shortness of breath • Wheezing • A feeling of tightness in the chest

24. Dealing with Asthma • If there is outside activity going on, and there is to much of an allergen, than suggest a indoor activity. • Become friends with other’s suffering from asthma.

25. Technology in treating Asthma • Inhlaer allergy mask nebulizer
