Where does carbon dioxide exerted by the lungs come from?
From the mitochondria ( powerhouse of cells ) in cells that produces energy from oxygen inhaled and relieves carbon dioxide through osmosis in blood stream which then is exchanged by lungs for oxygen we inhale and the cycle continues.
How does it feel when part of your lung has collapsed?
Like a knife jabbing into your lung like a stitch. Not extremely painful but very uncomfortable.
If you are a heavy smoker and you developed a bad cough would you suspect emphezema or lung cancer?
I am a heavy smoker and I have a bad cough. I have chronic bronchitis, which is the first step toward emphysema, you can never rule out lung cancer though. You should get a chest x-ray.
How are the lungs adapted for gas exchange?
-The alveoli give the lungs a large surface area for absorbing oxygen and excreting carbon dioxide.
-Alveoli have thin walls so that gasses diffuse easily across them.
-The cappliaries which have thin walls make it so that substances can easily pass into and out of the blood.
This is all in the lung.
it also has adapted to relese a deadly neuro toxin when threatened by the kidney for its lunch money.
it does this onvoluntarily which is really annoying becuase you kill your self without even choosing to. this takes quite a while to kill you.
Many people have found the effects it does but are to arrogant to see the truth and just say that it is smoking that has caused it but smoking does no damage it was in fact the neuro toxin.
transverse and frontal
Does smoke go into the lung if you smoke?
no because you blow out the smoke but only the nicotine goes into your lungs
What is the purpose of definitive cancer therapy?
The primary purpose of definitive care is to establish a cure and to destruct and remove all cancer cells from the infected person.
Which breathing pattern results in decreased levels of carbon dioxide at the cellular level?
Hyperventilation
What do dark masses on your lungs mean if it's not pneumonia?
It means maybe you should be getting a second opinion. The alternatives are not pleasant.
What is serous membrane associated with the lungs?
The outer layer of a serous membrane is called the parietal layer and is always attached to the surrounding tissues. The inner layer is called the visceral layer and is firmly attached to the organ it covers
What does THC do to your lungs?
Thc itself is not harmful to lugs it is actually healthy. According to researchers, THC fights lung cancer by curbing epidermal growth factor (EGF), a molecule that promotes the growth and spread of particularly aggressive non-small cell lung cancers. It seems to go to receptor sites on cells and inhibit growth.
What are the symptoms tuberculosis have on the lungs?
Mycobacterium tuberculosis is spread by airborne droplets from infected people. These can then be inhaled by others. The infection begins by reaching the pulmonary alveoli where the bacteria is then taken up by macrophages in the lungs. The primary site of infection is referred to as the Ghon focus. Dendritic cells can pick up the bacteria and transport them to other parts of the body, leading to Miliary tuberculosis althought the bacteria cannot replicate within the dendritic cells. Standard unsupervised treatment of TB: 1st 2 months: Rifater (rifampicin, isoniazid, pyrazinamide) 65kg - 6 tabs Ethambutol 15mg/kg Next 2 months: Rifanah (rifampicin, isoniazid) 50kg 2 x 300mg tabs Mycobacterium tuberculosis is spread by airborne droplets from infected people.

As far as I'm aware, the lungs don't actually aid digestion, however there are a few things they do that might indirectly be helpful.
The consistent pressure changes in the thoracic cavity due to inspiration/exhalation, may exert some pressure/force on the oesophagus which may aid peristalsis, ensuring an easy transit of food to the stomach.
The only other thing is that breathing maintains a high oxygen concentration gradient, so we therefore have high availability of oxygen for respiration. All the cells in the digestive system must respire to create ATP for energy, and the oxygen needed comes from breathing through the lungs.
Can a 15 year old who has smoked for 2 years have lung cancer at 15?
Chances are small. Then again, a 15-year-old who never smoked may have lung cancer. You see, it increases the chance. Smoking doesn't give you lungcancer, it increases the chance of the formation of cancer taking place. But if you're 15 and there's no history of lungcancer in your family, then I wouldn't worry too much if I were you.
What is your chance of getting lung cancer when engaged in smoking?
It depends on how much you have smoked and for how long, 40 ciggs a day is very different from 5 a day. A very rough average for people in their 50's who have smoked since they where teenagers is 5-7% chance to develop lung cancer before they reach 65.
Here's a table with approximations: 1 pack a day for 30 years > less than 1%
1 pack a day for 35 years > about 3%
1.5 packs a day for 40 years > about 4%
2 packs a day for 45 years > about 8%
2 packs a day for 50 years > about 15%
Please note that your individual risk varies greatly depending on factors such as personal physice and general living conditions. However it's not at all certain that you will develop lung cancer because you smoke.
Does a filling cause an abscess?
If it is done correctly you should not get a filling. If there is infection in the cavity and it is not removed then there is a good chance you'll have an absess. You may have to take antibiotics the week prior to getting the filling. It just depends on your situation.
If a diver comes up to quickly would his lungs explode?
Yes. If they hold their breath their lungs would expand until the burst.
Where is the infrahilar region of the lung?
The right suprahilar region of the lung is located in the upper middle portion of this organ. The left lung also has a suprahilar region, but it is slightly bigger than the right.
What is mild scarring of the lung apices?
Mild scaring of the lung apices is a condition that might be seen on an x-ray of the lungs. This can be caused by a variety of illnesses and is treated by a physician.
Yes they can.. If you abuse them by smoking cigarettes.
