How many times per day do you think you breathe? You breathe about 25 times per minute, and about 36000 times per day What do you think is the purpose of breathing? • To get rid of waste carbon dioxide made by cells. • Help in regulating the concentration of hydrogen ion (PH) in your blood. • Keep oxygen concentration high and carbon dioxide concentration low in alveoli.
Why is carbon monoxide so deadly? It binds to hemoglobin (blood) more tightly than either oxygen or carbon, which minimizes the delivery of oxygen to all the tissues of the body.
What Is The Respiratory System? • The goal of the respiratory system is to deliver oxygen to your cells all through out your body. • From the help of the alveoli which takes the oxygen out of the air you breathe in and sends the oxygen into you blood stream which are then picked up by your red blood cells that carry it through out your body.
Parts Of The Respiratory System • Lungs- Are the main organs of the respiratory system. In the lungs oxygen is taken into the body and carbon dioxide is breathed out. Then the oxygen is picked up by the red blood cells. The red blood cells drop off the oxygen to the body cells, then pick up the carbon dioxide then the carbon dioxide is sent back to the lungs and we breathe it out when we exhale. • Trachea-filters the air we breathe and branches into the bronchi. • Bronchi-are two air tubes that are connected to the trachea and carry air directly into the lungs.
Parts Of The Respiratory System • Diaphragm-The diaphragm is the main muscle used in breathing. • Pharynx- Is the muscular tube that leads from the mouth to the gastrovascular cavity. • Larynx- is the area of the throat that has the vocal cords in it and produces vocal sounds. • Bronchioles- are very small airways that extend from the bronchi to the alveoli.
Parts Of The Respiratory System • Capillaries- A tiny blood vessel that allows an exchange between blood and cells in tissue • Alveoli- Tiny air cells of the lungs where oxygen and carbon dioxide are exchanged. Each lung contains 300-350 million aveolis.
Diseases of the respiratory system • Asthma- hypersensitive respiratory system airways that, when triggered, constrict. Constricted airways reduce the flow of air and cause trouble breathing. About 4,000 people die from asthma each year. You can be born with asthma or get it, and there are several treatments, but it can never go away. • Chronic Obstructive Pulmonary Disease (COPD)- includes chronic bronchitis and emphysema which 80-90% of (COPD) is caused by smoking. ChronicBronchitis- involves inflammation and scarring of the main airways, the bronchial tubes. Emphysema- is permanent damage to the walls of the air sacs and loss of lung elasticity.
Diseases of the respiratory system • Acute Bronchitis- is inflammation of the bronchial tubes which are the primary airways to the lungs and is usually caused by a viral or bacterial respiratory infection. • Sinusitis- inflammation of the sinus cavities. Anytime the small opening of the sinus cavities are blocked, sinusitis may occur. About 40 million people develop the respiratory disease each year. • Common Cold- Colds are upper respiratory infections that are really contagious. Cold viruses are mostly spread through sneezing and coughing and by touching contaminated objects.
Diseases of the respiratory system • Influenza- serious respiratory tract infection. The flu is highly contagious and spread from person to person from airborne viruses. • Pneumonia- can be a mild respiratory inflammation or it can require intensive-care hospitalization. Pneumonia affects about two million Americans annually, mostly those under age 40. • Pleurisy- respiratory inflammation of the pleural membrane lining the lungs and the chest cavity. • Lung Cancer- an uncontrolled growth of abnormal cells in lung tissue and More than 169,500 new cases of lung cancer were treated in 2001
Keeping your lungs healthyYou can keep your lungs healthy by: • Don’t smoke • Don’t expose yourself to pollutants such as second-hand smoke • Eat healthily
You can keep your lungs healthy anytime! Oxidation generates free radicals (that cause cell damage) and is partially to blame in the obstruction and stiffening of the lungs’ airways. • Vitamin C, is an antioxidant, and the main antioxidant you’d find on the surface of the lungs, and thus, you’d probably want to eat it. It is believed to fend off oxidation although this has not been proven.
You may also want To make sure you get plenty of: • Vitamin E • Omega-3 Fatty Acids (found in some nuts and fish) • Take a mulivitamin • Eat 5 a day of fruits and vegetables • Eat whole grains As WELL as things you’ll want to be sure to do: • Excersise • Maintain healthy weight • Drink caffeine In moderation
How Respiratory system was discovered • In 1627-1691 A.D Robert Boyle and Robert Hooke discovered that parts of the body acted as pumps • John Mayow showed that what animals need is the same substance fire needs to burn • In 1771, a swedish chemist discovered oxygen
Keep oxygen concentration high and carbon dioxide concentration low in alveoli. • To get rid of waste carbon dioxide made by cells.
