  2. 2. Respiratory System We need energy for life for all of our daily activities. Our respiratory system is responsible for supplying oxygen to our body. We need oxygen to get energy from the food that we eat. In fact, we need oxygen to carry out all of the chemical processes that are constantly going on in our bodies. Our respiratory systems obtain oxygen from the air and pass it to our blood which then carries it to our entire body.
  3. 3. Basic Part of the Respiratory System The six basic part of respiratory system are      Nose      Pharynx      Larynx      Trachea      Bronchi      Lung
  4. 4. Nose is the first and last organ that air passes through. The nose serves some important functions. As part of the conducting zone, it cleans the air of dust and other impurities, warms the air if it is too cool, and moistens the air if it is dry Basic Part of the Respiratory System
  5. 5. Pharynx most commonly known as the throat. Its happen like a funnel. It serves duel purposes. Not only does move the air into your lungs, but it also moves food into your stomach. About five inches long, the pharynx is separated into three distinct regions, chosen by location and function: the nasopharynx, the oropharynx, and the laryngopharynx Basic Part of the Respiratory System
  6. 6. Larynx also known as the voice box, the pharynx is what allows you to speak. The larynx has an inlet at the top that allows substances to pass through it or not. When food is being swallowed, the inlet is closed, forcing food into the stomach. When air is being breathed, the inlet is wide open so that air can enter your lungs. Basic Part of the Respiratory System
  7. 7. Bronchi the trachea branches off into two main bronchi, your left and right primary bronchi, which lead to the left and right lung respectively. Bronchi help in gaseous exchange within lungs. Basic Part of the Respiratory System
  8. 8. Bronchi the trachea branches off into two main bronchi, your left and right primary bronchi, which lead to the left and right lung respectively. Bronchi help in gaseous exchange within lungs. Basic Part of the Respiratory System
  9. 9. Basic Part of the Respiratory System Lungs are cone-shaped and extend from the collarbone to the surface of the diaphragm. The mid-line of each lung contains a region known as the hilus, the area through which blood and lymphatic vessels, nerves and primary bronchi enter and leave. Each lung is divided into lobes. Once the air reaches the alveoli, exchange of gases occur. Diffusion of gases takes place across the thin capillary and alveolar walls. Oxygen is passed into the capillaries for supply to body tissues and carbon dioxide is passed from the capillaries to the alveoli to be expelled from the body during exhalation.
  10. 10. Functions of the Respiratory System The functions of the Respiratory System are      Respiration      Vocalization      Coughing
  11. 11. Functions of the Respiratory System Respiration When you inhale and exhale you begin a process of oxygenation to your entire body When you inhale your lungs become filled with air, oxygen . Inhale Exhale When you exhale your lungs release carbon dioxide. The most important function of the respiratory system is the process of respiration. How does the respiratory system function? Let us have a look at it in detail
  12. 12. The Vocalization is also one of the major respiratory system functions. Vocalization is the process which enables humans to speak and also to make sound. When the air passes through the pharynx and larynx, it makes the vocal cords in larynx to vibrate which helps in production of sound and speech in humans . Coughing When any foreign particles enter the nasal passages, it can result into irritation. Therefore, expelling out these foreign bodies or irritants is one of the functions of the respiratory system. These irritants are forced out of the respiratory tract through cough or even sneeze. Relation between the Respiratory System and the body . Vocalization
  13. 13. The respiratory system effects many of the body's other systems and processes in a number of ways The circulatory system sends deoxygenated blood to the lungs, where it is again oxygenated and returned to the heart, so it can be pumped to tissues and organs throughout body Repiratory System Process Lymphatic System: The lymph system helps to maintain the fluid balance in the lungs Nervous System: Various sensors and receptors in the lungs are sensitive to inflation, deflation, and chemical stimulation and can activate the nervous system. Immune system: Foreign particles and cells in the respiratory system stimulate the immune system to release macrophages and lymphocytes as protection Exocrine System: The lungs and the kidneys work together to maintain proper oxygen levels in the blood
  14. 14. The function of the respiratory system is to deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs . Relation between the Respiratory System and the body . External respiration is the process of gas exchange between the lungs and the blood Pulmonary ventilation    is the process of breathing—inspiration (inhaling air) and expiration (exhaling air). Gas transport, carried out by the cardiovascular system, is the process of distributing the oxygen throughout the body and collecting CO2 and returning it to the lungs Internal respiration is the process of gas exchange between the blood, the interstitial fluids (fluids surrounding the cells), and the cells. Respiration includes the following processes
  15. 15. Your respiratory system is mainly your lungs which are located in your chest . Location of the Respiratory System Figure A shows the location of the respiratory structures in the body. Figure B is an enlarged image of airways, alveoli, and the capillaries. Figure C shows the location of gas exchange between the capillaries and alveoli .
  16. 16. Common respiratory disorders include: Diseases that are associated with the Respiratory System . Chronic Bronchitis - Any irritant reaching the bronchi and bronchioles will stimulate an increased secretion of mucus. Chronic Obstructive Pulmonary Disease (COPD) - Irritation of the lungs can lead to asthma, emphysema, and chronic bronchitis and people can develop two or three of these together. Emphysema - The delicate walls of the alveoli break down, reducing the gas exchange area of the lungs. Asthma Periodic constriction of the bronchi and bronchioles makes it more difficult to breathe Pneumonia - An infection of the alveoli. It can be caused by many kinds of both bacteria and viruses. Tissue fluids accumulate in the alveoli reducing the surface area exposed to air. If enough alveoli are affected, the patient may need supplemental oxygen.
  17. 17. Exercise. You may also make your lungs feel loved by performing a daily exercise. Daily routine of exercise does not only help the respiratory system but also maintains the wellness of the other body organs . Quit smoking Smoking brings dirt and bacteria to the respiratory system. Smoking makes the lungs weak. Maintain a balanced diet. Too much weight brought by overeating results to more respiratory failure. Thus to prevent these diseases and to maintain a healthy respiratory system, you have to consider the following diet tips for your respiratory system Get a medical check up. The best way to take care your respiratory system is to get a yearly check up. This check up will help you detect possible disease/s within your body - especially your respiratory system. Ways in which the respiratory system can be healthy
