  1. The Respiratory System By: Nikki Peterson , C.J. Boswell , Amanda Shepherd ,& Jewel Inlow

  2. What are the major functions of the Respiratory System? • Breathing moves the chest to bring air into and remove waste from the lungs. • Cell respiration uses oxygen to release energy from glucose.

  3. The Major Parts of the Respiratory System • Trachea – connects larynx with the bronchi • Lungs – where air is carried into • Diaphragm - helps gas move in and out of your body • Epiglottis – when you swallow it folds down which allows food and liquids to enter your esophagus instead of your airway • Larynx – is the airway to which two pairs of horizontal folds tissue,called vocal cords, are attached • Vocal Cords – enables us to talk, laugh, sing, hum, whisper, cough, and sneeze

  4. Breathing Process • Breathing is partly described as the result of changes in volume and resulting air pressure. As you inhale your lungs expand as you exhale, your lungs get smaller. • Your diaphragm contracts and relaxes, changing the volume of the chest, which helps move gases into and out of your lungs.

  5. How the Respiratory System Works With Other Systems • The respiratory system works with the circulatory system when air goes through the lungs containing oxygen, it passes from the lungs into the circulatory system because there is less oxygen in blood when it enters the lungs than in cells in the lungs. • It affects the digestive system because oxygen releases energy from glucose. • Your respiratory system uses your lungs to supply oxygen to your cells for your circulatory system.

  6. 4 Facts About the Respiratory System • Your lungs inhale and exhale about 500ml of air with the average breath. • When you do strenuous activities like sports your breathing can increase to 2000ml of air per breath. • More than 85% of all lung cancer is related to smoking. • The breathing rate is faster in children and women than in men.
