Group RESPIRATORY SYSTEM GROUP RESPIRATORY SYSTEM /ˈres.pɚ.ə.tɔːr.i ˌsɪs.təm/ • The network of organs and tissues that help you breathe • This system helps your body absorb oxygen from the air so your organs can work • It also cleans waste gases, such as carbon dioxide, from your blood • Common problems include allergies, diseases or infections FUNCTIONS • Helping you inhale (breathe in) and exhale (breathe out) • Allows you to talk and to smell • Warms air to match your body temperature and moisturizes it to the humidity level your body needs • Delivers oxygen to the cells in your body • Removes waste gases, including carbon dioxide, from the body when you exhale • Protects your airways from harmful substances and irritants THE PARTS OF THE RESPIRATORY SYSTEM Mouth and nose Sinuses /ˈsaɪ.nəs/ Openings that pull air from outside your body into your respiratory system Hollow areas between the bones in your head that help regulate the temperature and humidity of the air you inhale Pharynx (throat) /ˈfer.ɪŋks/ Tube that delivers air from your mouth and nose to the trachea (windpipe) THE PARTS OF THE RESPIRATORY SYSTEM Ribs Bones that surround and protect your lungs and heart Lungs Diaphragm /ˈdaɪ.ə.fræm/ Muscle that helps your lungs pull in air and push it out Two organs that remove oxygen from the air and pass it into your blood THE PARTS OF THE RESPIRATORY SYSTEM Trachea /ˈtreɪ.kiə/ Passage connecting your throat and lungs Alveoli /ælˈvi əˌlaɪ/ Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place Bronchial tubes /ˈbrɒŋ.ki.əl/ /tuːb/ Tubes at the bottom of your windpipe that connect into each lung THE PARTS OF THE RESPIRATORY SYSTEM Bronchioles /ˈbrɑːŋ.ki.oʊl/ Small branches of the bronchial tubes that lead to the alveoli Capillaries Blood vessels in the alveoli walls that move oxygen and carbon dioxide Alveoli Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place THE PARTS OF THE RESPIRATORY SYSTEM Larynx (voice box) /ˈler.ɪŋks/ Hollow organ that allows you to talk and make sounds when air moves in and out INFLUENCE CONDITIONS Allergies /ˈæl.ə.dʒi/: Inhaling proteins, such as dust, mold, and pollen, can cause respiratory allergies in some people These proteins can cause inflammation in your airways Asthma /ˈæs.mə/: A chronic (long-term) disorder, asthma causes inflammation in the airways that can make breathing difficult Infection /ɪnˈfekt/: Infections can lead to pneumonia (inflammation of the lungs) or bronchitis (inflammation of the bronchial tubes) Common respiratory infections include the flu (influenza) or a cold INFLUENCE CONDITIONS Disease: Respiratory disorders include lung cancer and chronic obstructive pulmonary disease (COPD) These illnesses can harm the respiratory system’s ability to deliver oxygen throughout the body and filter out waste gases Aging /ˈeɪ.dʒɪŋ/ : Lung capacity decreases as you get older HOW CAN I KEEP MY RESPIRATORY SYSTEM HEALTHY? You should: • Avoid pollutants that can damage your airways, including secondhand smoke, chemicals and radon (a radioactive gas that can cause cancer) • Wear a mask if you are exposed to fumes, dust or other types of pollutants for an Total Number of Cases in Viet Nam 11,521,70 Coronavirus disease 2019 /kəˈrəʊ.nəˌvaɪə.rəs/ /dɪˈziːz/ Is an acute infectious respiratory disease caused by the coronavirus SARS-CoV-2 and its variants The main mode of transmission is person-to-person transmission, usually via respiratory droplets that people sneeze, cough or exhale Cystic fibrosis /ˌsɪs.tɪk faɪˈbrəʊ.sɪs/ It is a life-threatening genetic disease that causes the body to produce thick mucus This thick mucus can build up and clog ducts and other ducts in the lungs, digestive tract, and pancreas Emphysema /ˌem.fəˈsiː.mə/ This can be understood as a type of chronic obstructive pulmonary disease that causes the lungs to inflate too much Chronic Bronchitis /ˈkrɒn.ɪk/ /brɒŋˈkaɪ.tɪs/ Type of chronic obstructive pulmonary disease (COPD) This is an acute bronchitis condition that is not treated definitively, causing repeated recurrences, leading to severe damage to the bronchial tubes DOCUMENTS https://dictionary.cambridge.org/ https://www.medicalnewstoday.com/ https://www.wikipedia.org/ https://med.stanford.edu/ Unit from Teacher THANK FOR LISTENING
