Transcript

  1. Part I: The Respiratory System UIC Urban Health Club •

    The respiratory system starts at the nose and mouth. The pharynx then connects them to the esophagus. It then continues past the larynx where the vocal cords are also found, and into the trachea which then takes air to and from the lungs using the left and right main bronchus • Upon inhalation air enters through the nose and mouth and travels to the lungs which expands to hold air by the use of the diaphragm. • In the lungs, gas exchange occurs allowing oxygen to diffuse into the blood in the pulmonary arteries, along with taking the carbon dioxide from the blood.
  2. Part I: The Respiratory System UIC Urban Health Club •

    The diaphragm is a muscle below the lungs used to expand and contract the lungs to inhale and exhale respectively. • The diaphragm moves downward and contracts thereby creating a vacuum in the lungs and allowing air to be taken in. • The muscles in the abdomen can also be used in conjunction with the diaphragm often causing more forceful breathing.
  3. Part I: The Respiratory System UIC Urban Health Club •

    The heart and lungs work together very closely in order to oxygenate all of the blood in your body. • The pulmonary artery carries deoxygenated (blue) blood from the right side of the heart to the lungs where it becomes oxygenated (red). • The pulmonary vein carries the oxygenated blood from the lungs to the left side of the heart where it is then pumped out to the rest of the body. • Most of the oxygen that we breathe in is carried in the blood by a small protein called hemoglobin. • We can measure how much oxygen is in our blood by using a pulse oximeter.
  4. Part I: The Respiratory System UIC Urban Health Club •

    Hemoglobin is a small protein that carries oxygen and carbon dioxide throughout your body. • Hemoglobin carries oxygen to your tissues and returns carbon dioxide from your tissues back to your lungs where it is blown off as we exhale. • One hemoglobin molecule contains a molecule of iron and multiple protein chains. • Each hemoglobin can carry up to 4 molecules of oxygen.
  5. Part II: A Closer Look at the Lungs UIC Urban

    Health Club • The lungs have lobes ◦ The right lung is divided into 3 lobes. The left lung is divided into 2 lobes. ◦ The left lung is smaller to allow room for the heart in the chest cavity. • The lungs are not hollow; they are composed of sponge-like tissue • When inside the womb, a baby’s lungs are filled with fluid. Once born, it takes around 10 seconds for a baby to take its first breath, and is the result of the change in environment
  6. Part II: A Pathway of How Your Lungs Work UIC

    Urban Health Club 1. As you breathe in oxygen through your nose and mouth, the diaphragm flattens. 2. The air passes through the throat into the trachea (windpipe), where it divides into the left and right bronchi. 3. Each bronchus divides into smaller branch-like structures and end in small alveoli. 4. The alveoli are surrounded by capillaries carrying red blood cells. 5. The process of gas exchange occurs at the alveoli.
