  1. Emphysema Respiratory System influenza Bronchitis

  2. Respiratory System Functions (Jobs) • Getoxygen from environment • Remove waste (carbon dioxide, water) • Produce sound

  3. Respiratory System • A person at rest takes an average of 12-15 breaths per minute • Your right lung is slightly larger than your left lung • The surface area of your lungs is about the size of a tennis court • A sneeze travels faster than a cough (100 mph vs. 60 mph) • Facts

  4. Respiratory System • Oxygen (O2) is needed by the cells in the body to stay alive and perform their specific jobs • Glucose (sugar) is also used to release energy • Carbon dioxide (CO2) and water (H2O) are created during this process and are waste products that must be removed • Cellular Respiration O2 In CO2 Out

  5. Check Yourself • In two sentences, summarize cellular respiration. • Try to write a formula for cellular respiration. • Cellular Respiration O2 In CO2 Out

  6. Respiratory System • Oxygen breathed into lungs (inhaled) • Alveoli (air sacs) allow oxygen to move into blood stream • Red blood cells carry oxygen to cells of body • Oxygen moves into cells • Gas Exchange • (Inhale) O2 In

  7. Respiratory System • Carbon dioxide is removed from cells • Red blood cells carry CO2 to lungs • Alveoli allow carbon dioxide to leave blood stream • Carbon dioxide is breathed out of lungs (exhaled) • Gas Exchange • (Exhale) CO2 Out

  8. Respiratory System • The diaphragm is muscle that controls the movement of air in and out of lungs • When diaphragm contracts, lungs expand and take in air • When diaphragm relaxes, lungs contract and push out air • Breathing • Breathing • Simulation

  9. Respiratory System • The nose warms air filters out particles and adds moisture • The epiglottis blocks out food and liquids when you swallow • The trachea directs air down to the lungs • Other • structures

  10. Check Yourself • In a few sentences, summarize the path that air takes and what happens to it on the way to the lungs. • What do you think would happen if your epiglottis didn’t close the stomach off all the way when you breathed in?

  11. Respiratory System • Bronchitis • Bronchial passages within the lungs narrow & then become clogged with mucus. • Emphysema • Alveoli within the lungs become damaged or destroyed preventing the effective exchange of oxygen & carbon dioxide. • Lung cancer • Uncontrolled growth of lung cells that produce tumors that prevent the lung from operating effectively. • Asthma • Disorder where the passageways in the lungs swell and become narrow making it difficult for the lungs to take in air • Diseases

  12. Respiratory System • Speaking/singing/whispering – air moves over vibrating vocal cords • Exhale – removes extra moisture • Coughing/sneezing – remove items from windpipe or lungs • Sighing • Yawning • Hiccupping • Laughing • Crying • Other Jobs
