2. What is the role of the respiratory system in the human body? The respiratory system is responsible not only for our breathing, but to get Oxygen to all of our organs. Oxygen gets to our organs through the alveoli in our lungs from there it is put into the bloodstream. Then, it is distributed to the organs where it is involved in a chemical reaction to produce energy for the body to function. Without this, we wouldn’t survive.

3. Question 3: How do These Organs Work Together? As the bronchial tubes go through the lungs, they change into smaller air passages called bronchioles. The bronchioles stop in very small balloon-like air sacs called alveoli. Your body has over 300 million alveoli! The alveoli are surrounded by tiny blood vessels called capillaries. Oxygen from the air that was inhaled passes through the alveoli walls and into the blood. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then returns the carbon dioxide back to your lungs via the capillaries, where it is removed from the body when you exhale.

4. Question 3: How do These Organs Work Together? The Diaphragm is the muscle that allows us to breathe in or out, it contracts when we breathe in, which creates a vacuum to such air in. When we breathe out, the Diaphragm expands, pushing up on the lungs, allowing them to deflate. When we breath air in our nose or mouth, the air travels to the back of your throat, to the windpipe, or trachea. The trachea then divides into air passages called bronchial tubes.

5. Question 4: How is Your System Connected to Two Other Body Systems? Digestive System The Respiratory system works along side with the digestive system, because the Respiratory system provides the muscles in the Digestive system with Oxygen so they can operate correctly. Also, the Digestive system provides nutrients to the organs in the respiratory system, like the diaphragm, and the intercostal muscles.

6. Question 4: How is Your System Connected to Two Other Body Systems? Nervous System The Respiratory system gives the brain oxygen so that it can function normally. The Respiratory system also removes carbon dioxide from the cells of the brain, which is waste products of brain cells.

7. Question 5: What are the Levels of Organization in Humans? The Diaphragm is made up of skeletal muscle tissue Skeletal Muscle tissue is composed of Skeletal Muscle cells One organ in the Respiratory system is the Diaphragm Diaphragm Skelatal Muscle Tissue

8. Question 8: Name and Describe Two Professions That Work With This System. Pulmonologist A pulmonologist is a physician who specializes in the diagnoses and treatment of diseases and disorders within the respiratory system. Pulmonologists treat diseases and disorders including breathing disorders, and may also treat sleep disorders, severe allergies, and other lung conditions and diseases.

9. Question 8: Name and Describe Two Professions That Work With This System. Respiratory Therapist They Inspect patients Respiratory system, provide breathing and blood tests, and if needed, they implement respiratory therapy care plans for patients. A Respiratory Therapist’s duties include operating, maintaining, and inspecting Respiratory equipment such as ventilators, anesthetic machines, oxygen delivery devices and other equipment.

10. Question7:How can you maintain a health system?  Every day you need to breathe fresh air.  Put some plants in your home.  Don’t smoke.  If you can’t do the third one, you can drink milk, surveys show, it can reduce your risk of lung cancer.  Eat lots of vegetables or drink fruit and vegetable juice.  Do not do intense sports. You needs to do these things :

11.  Question 9:“Did you know facts?” The capillaries in the lungs would extend 1,600 km if placed end to end. Hairs in the nose help to clean the air we breathe as well as warming it. The surface area of the lungs is roughly the same size as a tennis court. The right lung is slightly larger than the left. We lose half a liter of water a day through breathing. This is the water vapour we see when we breathe onto glass. Did you know these facts?

15. The Major Organs in the Respiratory system. The lungs are two spongy organs that are on either side of the chest, they are filled with air. The trachea, otherwise known as the windpipe,takes the air we breath and puts it into the lungs through tubular branches called bronchioles. These bronchi keep getting smaller, eventually becoming microscopic. The bronchioles finally end with microscopic air sacks called alveoli. This is how the oxygen gets into the bloodstream. The diaphragm is a muscle shaped like a dome at the bottom of the chest cavity. When we breathe in, the diaphragm rises and when we exhale it goes down.

19. Asthma Asthma is a disease where the muscles in the bronchi contract, making it harder for the person to get oxygen. Asthma can be brought on by different triggers such as air pollution, smoke, different types of fumes, and cleaning supplies. Symptoms that are involved in Asthma are, wheezing, coughing, having trouble breathing and chest tightening. There is no cure for asthma (Sometimes, younger kids grow out of asthma when the get older) but you can take short term medications such as puffers to control the swelling so you can breath better.

20. Lung Cancer Lung cancer is a disease where the cells go out of control in the lung and multiply uncontrollably. Most cancer that grows in the lungs, begins in the epithelial tissue. Some things that can contribute to lung cancer are smoke, air pollutions or second hand smoke. Although there is no actual cure for cancer, doctors have found things that have helped slow down or eliminate the tumors. Chemotherapy is where certain drugs are injected into your system. Patient’s that have this treatment done often lose their hair since these drugs target cells that are always going through mitosis. Radiation therapy is where doctors target the malignant tumor. This damages the cells DNA, and this leads to the cells dying. To spare organs and/or skin that doesn’t have cancerous cells, shaped radiation beams are used to target the cells from different angles.
