Epiglottis Its a flap that covers the opening to your lungs while youre swallowing so you dont inhale food. . Coughing When you cough you argon either releasing mucose or germs or some other Irritant In the lungs. E. sketchy rings of Trachea Prevent the trachea and bronchioles from collapsing and closing up. F. Fat and protein direct lining the Inner wall of the alveoli Surfactant In the alveoli causes them to effectively breathe open during the whole respiration/ airing process.When there is lack of bedwetter the alveoli can collapse on themselves causing less surface sphere of influence for gas qualify, hence causing breathing difficulties/shortness of breath overdue to the decreased ability for oxygen exchange. G. Pleura& lymph between he two layers They gaming a critical role In immunological responses in two local and systemic diseases. It is positioned to respond to inflammatory changes in the lung permanency. The pleura functions not scarcely as a mechanical barrie r, but also as an immunologic and metabolically responsive membrane that is Involved in maintaining a high-energy homeostasis in the pleural space. . Rib cage The rib cage argon a set of bones radiating from the Thoracic region of the vertebral column (not to be confused with the vertebral cord which is located inwardly the vertebral column). These bones are the ribs and sternum (or breast bone). They form a cage like structure around the very delicate variety meat such as the heart and the lungs. Not only do they nourish these organs, but they also support them, keeping them In place. Without the rib cage, your organs would all fall out of place. 2014 Grade and Section Aphrodite Instructor Mr. Eugene new 1 OFF 2.How does the internal respiration differ from the external respiration? External respiration is the exchange of gases between the alveoli and lung capillaries. Oxygen diffuses from the alveoli into the blood, while vitamin C dioxide moves from the blood in the alveol i. Internal respiration, in contrast, is the exchange of gases in organic structure tissues 3. What is a Third Hand Smoke? Third arrive at rotter is generally considered to be residual nicotine and other chemicals left on a variety of indoor surfaces by tobacco smoke. 4.What are some of the diseases caused by smoking? Cardiovascular Diseases- the main cause of death due to smoking. represent set of the arteries is a process that develops over years, when cholesterol and other fats deposit in the arteries, leaving them narrow, blocked or rigid. When the arteries narrow (atherosclerosis), blood clots are plausibly to form. Cancer- Smokers are more keel to get cancer than non-smokers. This is particularly honest of lung cancer, throat cancer and mouth cancer, which hardly ever affect non-smokers.Lung Diseases- chronic Obstructive Pulmonary Disease (COOP) is a collective term for a group of conditions that block airflow and make breathing more difficult. 5. beg off the mechanis ms of breathing in human. Mechanisms of breathing inspiration When you breathe in intercessor muscles between the ribs contract, pulling the knocker walls up and teethe plosive muscle below the lungs contracts and flattens, increasing the size of the chest the lungs increase in size, so the pressure inside hem falls. This causes air to rush in by the nose or mouth.Mechanisms of breathing expiration When you breathe out intercessor muscles between the ribs relax so that the chest walls move in and down. The diaphragm muscle below the lungs relaxes and bulges up, reducing the size of the chest. The lungs decrease in size, so the pressure inside increases and air is pushed up the trachea and out through the nose or mouth. 2014 Grade and Section 9-Aphrodite 6. Why are lungs considered as both respiratory as well as excretory organs? Lungs are the main organ of the respiratory system where gas exchange takes place. F something. . Name 2 Respiratory Diseases. How can they be prevent ed, detected and treated Names of the Respiratory Diseases How can they Prevented How can they Detected (What are the symptoms) How can they be Treated a. Lung Cancer -Dont smoke. -Stop smoking -Avoid second hand smoke Test -Avoid carcinogens at work -Eat a diet profuse of fruits and vegetables. -a cough that doesnt go away after two or tether weeks. -a long-standing cough that gets worse. -persistent chest infections. -coughing up blood. -an ache or pain when breathing or coughing. -persistent breathlessness. 1 .Non small cadre lung cancer can be treated with surgery, chemotherapy, radiotherapy or a combination of these, depending on the stage when the cancer is diagnosed. Some people with advanced lung cancer may stool biological therapy. There is information below about the treatment of non-small cell cancer by stage. B. Asthma -Learn about your asthma and ways to control condition it. Use medicines as your doctor prescribes. -Get regular check-ups for your asthma. Asthma symptoms, which include coughing, wheezing, and chest tightness, are common in an asthma attack. -Medicines -Follow an Asthma Action throw -Record Your Symptoms
