What is the role that your system plays in the human body? • The function of the respiratory system is to get oxygen to the rest of the body. The oxygen enters via the nose or mouth, and then travels through the rest of the respiratory system to the lungs. It is then transferred to the blood in the capillaries, where the red blood cells take it throughout the body, supplying every cell with oxygen. We need this system to stay alive. All cells go through aerobic respiration, which is the oxidization of glucose. This is how our cells get enough energy to function, providing us with healthy tissues, working organs, functioning organ systems, keeping us alive.
What are the major organs that make up your system? • The nose filters and warms the air. • The mouth can assist the passage of air. • The laryngopharynx is located between the hyoid bone, the larynx and the esophagus, it helps guide both food and air. • The oropharynx is a passageway that connects the back of the mouth and nose to the esophagus. The top section connects the nasal cavity to the region behind the soft palate, the middle is for food and air, and the bottom is just for food. • The nasopharynx communicates with the nasal cavity and provides a passage way for breathing. Located above the soft palate. • The larynx is a short section of the airway that connects the laryngopharynx to the trachea. The bottom of your larynx contains special structures called vocal folds, which allow you to talk and make noise.
The trachea provides a clear path for air to reach the lungs. The cilia on the epithelial cells helps trap contaminants like dust, to stop them reaching the lungs. • The diaphragm is underneath the lungs and is attached to the spine. It is the major muscle of respiration. When we breathe, it presses itself downward until it is flat, while the muscles in the ribs pull the ribs up, allowing the lungs to expand fully. • The lungs are two spongy organs that are located above the diaphragm. They are each surrounded by a pleural membrane that gives them room to expand, as well as negative pressure that allows them to fill slowly with air as they relax.
How do these organs work together • When we breathe in, we use the diaphragm. The diaphragm flattens out so the lungs have room to expand to allow air in. When breathing in, the air goes through the nose or mouth, down the windpipe, into bronchi tubes, and then air sacs called alveoli. • The alveoli help to clean out blood cells as they transfer oxygen to the blood. Then the waste gas is breathed out. That gas is called carbon dioxide. • From the lungs, blood returns back into the heart and is pumped to the rest of the body carrying oxygen with it.
Explain how your system is connected to two other body systems? • The circulatory system • We breathe in order to get oxygen to our red blood cells. When the lungs fill with oxygen, the oxygen is transferred to the blood in the capillaries inside our lungs. This is called external respiration. The oxygen is then carried by the blood cells to tissues all over the body. This is called internal respiration.
The digestive system • The digestive system also connects to the respiratory system because some of the passageways that are used for inhalation and exhalation are also passageways for food before it reaches the rest of the digestive system. For example: the mouth is used for both chewing (digestive) and breathing (respiratory). Likewise, the laryngopharynx is a passageway for both air and food.
What are the levels of organization in humans? • Organ systems like the respiratory system are made up of lots of organs working together. Organs are made up of different types of tissues, and each type of tissue is made up of cells with the same structure and function. For example, in the respiratory system, one organ is the diaphragm. The diaphragm is made up of many types of tissues, one of which is muscle tissue. Muscle tissue is made up of muscle cells.
Name two common diseases or disorders that directly affect your system • one disease that can affect the respiratory system is a disease called emphysema. This is caused when you smoke. What happens is it destroys the tissue in the persons lungs, but the tissues can not be regenerated. Once you have emphysema, doctors say it would be best and breath pure oxygen only to survive.
Another diseases is pneumonia . The effect of pneumonia is it causes your lungs to fill with a fluid or a pus. When you have pneumonia you have a lack or breathing, or in other causes you cant take in as much oxygen because of the fluid/pus. Pneumonia is caused by Bactria, viruses, fungi or parasites. • To not catch the disease emphysemas, you would simply quit or not smoke at all, if you already have the dieses, your doctor can give you special puffers. There is no real way to prevent pneumonia unless your doctor gives you medication. The disease can affect the young and healthy, but people over 50 years of age have greater risk of catching pneumonia • Lung infected with pneumonia
How can you maintain a healthy system? • To maintain a healthy respiratory system, you can either not smoke, work out so you are giving you’re the whole respiratory a work out and if you have asthma, use your puffers daily or when you need it. Another example that most people do when they live in a big city is breath in carbon dioxide from vehicles/buses or smog
Name and describe two professions that work with the system • Where do respiratory therapists work and what do they do? The respiratory therapist mostly works in hospitals and home care settings. A respiratory therapist is an indispensable part of the health care team, both in hospital and in home care settings. • Pulmonologists are physicians who specialize in evaluating and treating the lungs. This is a picture of a respiratory therapists
Facts • -Did you know that the highest record “sneeze speed "is 165 kph? • Breathing is so vital to life that it happens automatically. Each day, you breathe in about 20,000 times. By the time that you're 70, you'll have taken at least 600 billion breathes. • If the inside of your lungs was spread out flat, they would occupy roughly the same size of a tennis court • Did you know that our right lung is slightly bigger then our left lung because the right lung has 3 lobes and the left lung only have 2 • We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto glass
