Lungs facts the lungs are vital organs: lungs without we die. The primary function of the lungs, the gas exchange between the outside air and the blood. In the lungs, oxygen-poor blood provided with more oxygen (O 2 ) and carbon dioxide (CO 2 dispensed). When breathing is in this way, the waste CO 2 removed from the body. The amount of CO 2 which is separated has an influence on the pH, or the acid At the same content of the blood. In this way, the lungs also help to control the pH.
In addition to the breathing, lungs also have a function of the renin-angiotensin system, a hormonal system that is responsible for other things, the blood pressure and the water balance in the body.
Lungs facts Some species of mammals and birds, the lungs have a function in thermoregulation of the body: the right to keep the temperature of the body. The typical example is the dog panting when it’s hot.
The respiration is a vital mechanism which provides the body with oxygen and removes waste products from the body.
Breathing we do unconsciously; we should not think about it. But we can influence the process conscious: we can hold our breath or deliberately hyperventilate.
The process controlled by the respiratory center which located in the brainstem. The respiratory center continuously checks the CO 2 content in the blood. Under the influence of an elevated level of CO 2 in the blood, the respiratory center will ensure that the breathing speeds and that, if necessary, be used, the auxiliary or auxiliary breathing muscles.
In quiet breathing healthy adults about 12 to 16 times per minute.
Inhaling pulls the diaphragm (aperture) and the external intercostal muscles. As a result, the diaphragm pulls down and the ribs to the top and the front. The volume of the thorax is consequently bigger, the lungs expand (in which the elastic fibers stretched), and the oxygen-rich air drawn through the mouth or nose.
Lungs facts on the way to the alveoli pass through the air along the mucous membranes of the mouth or nose, throat, and bronchial tubes. The air is warmed and moistened it.
Dust particles continue to stick in the protective mucous lining of the respiratory tract and are transported by cilia toward the top to be coughed up, and swallowed.
In the alveoli, the gas exchange takes place: oxygen (O 2 ) diffuses from the alveoli into the blood, and carbon dioxide (CO 2 ) from the blood diffuses into the air in the alveoli.
Exhalation occurs at rest passively; no muscles stretched due to the elimination of the voltage of the intercostal muscles and the diaphragm. The elastic fibers will be in the lungs – which have stretched on the inhalation must be shorter. The thorax and lungs are smaller air pressed out of the lungs.
The route of our oxygen
Thanks to healthy lungs breathing automatic. Through the nose and mouth, we breathe a big gulp of air every few seconds inside. Then it enters the windpipe. The trachea can see as a reinforced pipe. The tracheal cartilage rings located. Allows the trachea is always open and the inhaled air can cover the route without further trouble. The trachea directly connected with our lungs. The trachea branched as it were, into the so-called bronchi.
These branch is getting further and further into the lungs until the inhaled air reaches the alveoli. Once we reach the lung alveoli, these sure that the oxygen can deliver to the blood. Our hearts then ensures that the oxygen can end up anywhere in the body. We can breathe thanks to the lung function and ensure that can provide the body with oxygen.
Mucosal protection as
Our lungs are very vulnerable and are therefore equipped mucosa. This mucous membrane located along the entire route traveled by the oxygen. From the nose and mouth, all the way to the lungs. This mucosa is an essential function of the lungs. The air is full of pollutants and bacteria that can enter directly into our bodies without mucosa. The mucosa has a protective function. The bacteria and contaminants remain as it were sticking to the mucosa. Also, the lung mucosa itself provided with cilia. Is there anyway dirt trapped in the lungs?
These cilia transport the debris immediately from the body and bring it back to the throat. Here we cough the mucus again if we swallow it. Thus again leave both coughed and through the feces, body. Thanks to the function of the lining keep our lungs clean and make harmful substances and bacteria less likely.
Excess mucous can cause pneumonia
At a little resistance, a virus or certain bacteria may happen that something does arrive in the lungs. This mucus production increases significantly. The body is working hard to get the body out of the dirt. Due to the large amounts of mucus sacs in the lungs can not do their job properly and will absorb less oxygen. You get stuffy and will cough up lots of mucus. Pneumonia therefore usually starts with a cold that will not go away and in many cases will be worse. Do you recognize the symptoms of pneumonia? Please always consult with your doctor. Today pneumonia in almost all cases properly treated. Thanks to the operation and function of the lungs we can live. Therefore make sure good!
The body has two lungs. The left and right lung wrapped in a wet sack (the pleura), and a layer of pleural fluid so that they can move smoothly while breathing. The breathing is done using the diaphragm, oozing and flat as you breathe in or out.
The ribs also assist in breathing by, with the aid of the muscles, to expand and to become smaller again. The air we breathe comes through the windpipe to the lungs. The air pipe opens into a left and right bronchus, which split into bronchi. The bronchi divide into smaller bronchioles and ending in bundles alveoli. The alveoli covered with capillaries, which absorb the oxygen from the alveoli, and are pressurization to the heart.
The heart pumps oxygen through the body. It takes 7 seconds until the oxygen to your toe or your brains has been. When the capillaries receive oxygen from the alveoli, capillaries give while their carbon dioxide [a gas in the air that you can not smell or taste] to the alveoli. Bringing it back to the windpipe to breathe out. The part of the brains that control the lungs is called the brainstem.
In your lungs are cilia. They are there to protect your lungs. If there is a speck of dust, the cilia will back up and then keep your lungs clean.
We use our lungs are not always equal. If you sit quietly reading a book, you’ll need less oxygen and do not have to dispose of carbon dioxide. For example, if you’re running, you require more oxygen. The amount of air that you breathe, you call the breath volume. The maximum amount of air that you breathe is called your vital capacity. You vital capacity depends a lot on your health, your weight, and your physical condition. Smoking can reduce vital capacity.
How hard you try, you can never break out your entire lung capacity; there will be air. This air hot air residue. When you breathe, will not further any inhaled air reaching your lungs. A portion of the inhaled air is stuck in your windpipe and your mouth and is not involved in gas exchange.
Problems with the lungs
As a result of a hole in the pleura can get collapsed lungs, we call this a collapsed lung. If you have an infection, for example, or if you suffer from heart failure, moisture can form behind the lungs. Aussies shortness of breath or tightness.
Inflammation in the lungs is called pneumonia. A common cause of pneumonia, the bacterium Streptococcus pneumonia. Pneumonia can occur when you cough hard, for example after a rib break or surgery coughing painful.
Lungs facts when a malignant tumor is growing in the lungs, it is called cancer. Lung cancer is a leading cause of death in the United states and is mainly caused by smoking.
Lungs Facts and numbers
The half of smokers begin in the schoolyard. Children go faster smoke if their friends do; see smoke, smoking does. The sooner a child starts smoking, the more likely it is that he gets addicted. And the harder it is to quit later.
Lungs facts on January 1, 2014, the government increased the age limit for tobacco sales from 16 to 18 years and the campaign NIX18 launched. Beginning in 2016 it adopted an amendment that makes school compulsory school grounds smoking 2020.
They want to discourage smoking by children.
70% of smokers begin before his 18th smoking.
41% of all smoking children has ever made a quit attempt.
half of the children who start smoking to it dies.
HALF OF ALL SCHOOLS HAS BEEN A NON-SMOKING AREA
Everyone agrees that children should get lessons in the healthy smoke-free environment, this also includes a smoking area at school. At school, you plug anything in!
No one wants children to smoke. Please help. Our School smoking and let children grow up smoking. Together towards a smoke-free generation.
