Main parts of the respiratory system: nose/oral cavity, trachea, bronchi, bronchial tubes, alveoli, lungs Other parts: pharynx, epiglottis, vocal fold, lobar broncus, diaphragm, etc.
Seems like a homework quesiton... The trachea is the cartilagenous tube between the nose/mouth to the lungs. It is at the front of your neck it passes in between the two heads of collar bone.
What is removed from the body when you exhale?
The respiratory system functions almost elusively to add oxygen to the blood and remove carbon dioxide. Incidental to this it also can be a way to remove some volatile chemicals from the blood.
How does poor nutrition effect the circulatory system?
It puts a strain on the heart because of all the extra miles of blood vessels it has to pump through.
Does bacteria help the respiratory system?
The respiratory system has a number of nonspecific defenses against disease. The hairs of the nose trap dust and pathogens. Mucus in the upper and lower respiratory system traps foreign bodies and pathogens. The cilia constantly move the mucus with this trapped material out of the system. The cough and sneeze reflexes also offer protection.
How does EPIGLOTTIS protect the respiratory system?
The epiglottis protects the trachea, which handles breathing. When you swallow food, the epiglottis covers the entrance to the trachea so food doesn't get in. Occasionally small bits of food do get in, and that's when you hear people say things like "My food/drink just went down the wrong pipe." Fortunately, for small bits of food like this, coughing it up is usually enough to expel it.
What are facts about respiratory system?
1. Humans have two lungs (left and right)
2. Humans have a trachea and mainstem bronchus.
3. Humans have bronchi stemming from the mainstem bronchus.
... and there are ever so many more facts on the respiratory system.
How does respiratory differ from breathing?
BREATHING- It is the intake of oxygen and release of carbon dioxide. RESPIRATION-It involves breathing and breakdown of food with and release of energy with the help of oxidation of blood.
Do the respiratory system work with other systems?
It works with all other systems . All systems in body are coordinated . The digestive system provides energy. The skeletal system protects it. Nervous system sends the signals. Circulatory system takes the oxygen rich blood and takes the oxygen poor blood back. The muscular system moves it. The immune system fights against diseases and protects it from sicknesses.
What does air pressure in the chest cavity increases?
Ok when you are inhaling air, the diaphragm is the one increasing the volume of your lungs. Since your lungs are expanding the ribs are moving forward and the spaces between them are increasing. When you are exhaling the diaphragm is moving up and the chest is lungs are relaxing and the ribs are moving back into there original position.
What if one of your ribs is swollen and it hurts to breathe?
could be your kidneys, you should consulte your doctor immedialtly it could be serious
How does the repiratory system help the rest of the body?
The work of respiratory system is to filter the air which is being intaken, then absorb the oxygen from alveolies which are present in the lungs into the blood so that each and every part of the body could get the oxygen to be alive and to carry vital body functions.
"Crackles" are a very descriptive term for the sound whose medical name is rales. Rales may be a sign of pneumonia, among other conditions.
What are the bronchial tubes and what do they do?
The bronchial tubes (or bronchi) are the large tubular structures within the lungs. These carry air into the lungs from the trachea. They branch into smaller tubes called bronchioles, and then to the smallest tubes that contain the alveoli (air sacs) of the lungs.
Which phase of breathing inhalation or exhalation is considered active and passive?
Inhalation is an active process and exhalation is a passive process
In a similar way to what you do when your car breaks down (forgive the analogy) - a bit of your car does not work, it prevent's your car from running properly. You go to the mechanic and find out what's wrong, they say they have to order in a car part for you. However the new car part is not quite the same; until it's put in place it's not possible to know whether it's going to work or not. You take your car back to them to have the new part put in. Hopefully it works, or at least does a decent attempt at working...
It's a case of replacing the bit of you that doesn't work, with a bit that hopefully does work. Obviously with a lot of post-transplant medication afterwards.
What organ system moves air into around and out of your body?
The respiratory system is the organ system that moves air into and out of your body.
Is it dangerous to breathe pure oxygen?
We breathe air that is 21 percent oxygen, and we require oxygen to live. So you might think that breathing 100 percent oxygen would be good for us -- but actually it can be harmful. So, the short answer is, pure oxygen is generally bad, and sometimes toxic. To understand why, you need to go into some detail …
Your lungs are basically a long series of tubes that branch out from your nose and mouth (from trachea to bronchi to bronchioles) and end in little thin-walled air sacs called alveoli. Think of soap bubbles on the end of a straw, and you'll understand alveoli. Surrounding each alveolus are small, thin-walled blood vessels, called pulmonary capillaries. Between the capillaries and the alveolus is a thin wall (about 0.5 microns thick) through which various gases (oxygen, carbon dioxide, and nitrogen) pass.
When you inhale, the alveoli fill with this air. Because the oxygen concentration is high in the alveoli and low in the blood entering the pulmonary capillaries, oxygen diffuses from the air into the blood. Likewise, because the concentration of carbon dioxide is higher in the blood that's entering the capillaries than it is in the alveolar air, carbon dioxide passes from the blood to the alveoli. The nitrogen concentration in the blood and the alveolar air is about the same. The gases exchange across the alveolar wall and the air inside the alveoli becomes depleted of oxygen and rich in carbon dioxide. When you exhale, you breathe out this carbon dioxide enriched, oxygen-poor air.
Now what would happen if you breathed 100 percent oxygen? In guinea pigs exposed to 100 percent oxygen at normal air pressure for 48 hours, fluid accumulates in the lungs and the epithelial cells lining the alveoli. In addition, the pulmonary capillaries get damaged. A highly reactive form of the oxygen molecule, called the oxygen free radical, which destroys proteins and membranes in the epithelial cells, probably causes this damage. In humans breathing 100 percent oxygen at normal pressure, here's what happens:
- Fluid accumulates in the lungs.
- Gas flow across the alveoli slows down, meaning that the person has to breathe more to get enough oxygen.
- Chest pains occur during deep breathing.
- The total volume of exchangeable air in the lung decreases by 17 percent.
- Mucus plugs local areas of collapsed alveoli -- a condition called atelectasis. The oxygen trapped in the plugged alveoli gets absorbed into the blood, no gas is left to keep the plugged alveoli inflated, and they collapse. Mucus plugs are normal, but they are cleared by coughing. If alveoli become plugged while breathing air, the nitrogen trapped in the alveoli keeps them inflated.
The astronauts in the Gemini and Apollo programs breathed 100 percent oxygen at reduced pressure for up to two weeks with no problems. In contrast, when 100 percent oxygen is breathed under high pressure (more than four times that of atmospheric pressure), acute oxygen poisoning can occur with these symptoms:
- Nausea
- Dizziness
- Muscle twitches
- Blurred vision
- Seizures/convulsions
Such high oxygen pressures can be experienced by military SCUBA divers using rebreathing devices, divers being treated for the bends in hyperbaric chambers or patients being treated for acute carbon monoxide poisoning. These patients must be carefully monitored during treatment.
What is the purpose of the alveoli and where is it located?
Alveoli are tiny sacs of air located in your lungs. There are millions of them in your lungs, and they fill up with oxygen when you inhale. They greatly increase the surface area of the lungs so that more oxygen can enter your bloodstream.
How do you give yourself the Heimlich maneuver?
I really, really hope this wasn't something asked in real-time.
The first thing to do is call 911 or your local emergency number. Make as much noise (grunting, humming, whatever) as you can and drop the phone but DON'T hang it up.
Even if you can't speak, someone will be sent to investigate the phone call.
If you can still breathe, cough, or talk at all, the heimlich won't work. Just keep coughing, try to take deep, slow breaths between coughs, and keep working at it.
If you're unable to breathe, cough, or talk, the easiest way to self-administer the heimlich is with the back of a chair or other similarly-shaped sturdy object. Bend over the back of the chair with the arms or back just under your ribcage, then allow yourself to drop slightly so that your body weight causes you to "fall" onto the back of the chair. This will create pressure in your lungs and hopefully, expel the obstruction.
What process moves oxygen from the alveoli to the capillaries?
The process is usually referred to as diffusion. This happens when concentrations in different areas interchange to give a more even mixture. Going through a membrane ( in this case the lung's alveoli wall ) would more properly require the process to be called osmosis, but that term is not usually used medically.
