Lungs

description of the bronchioles

Trachea> Bronchii> Bronchioles (smaller branches of bronchii) > Alveoli

A Bronchoscope is used by a physician to perform a bronchoscopy. This test involves passing the scope which has its own built in light source through the patients nose and on into the main bronchus and the if required the bronchioles. The physician can then examine these structures for abnormalities and take samples of tissue and fluid from the lungs via the biopsy channel of the bronchoscope.

carbon dioxide

The tissue of smokers' lungs contains residue of tar and nicotine formed from the smoke. It effectively blocks oxygen from mixing with the blood, and creates the conditions for carcinoma. Non-smokers' lungs generally do not.

It may mean that there are changes in how much the patient is able to exhale into the mylar balloons frequently used to measure lung function.

The trachea is the big straight tube that brings air to the lungs. The trachea then divides into main stem bronchi, lobar bronchi, segmental bronchi, bronchioles, etc.

The large decrease in blood pressure as blood moves through the lungs may prevent efficient circulation through the rest of the body.

Normally, the pressure in the lungs is greater than the pressure in the pleural space surrounding the lungs

residual volume

The lungs function to oxygenate blood and rid it of gases. When we inhale, oxygen travels into our lungs, diffuses into our blood stream and is pumped throughout our body where it can feed our bodies cells. Gases and other wastes from our cells then diffuse back into our bloodstream and travel to the appropriate areas to be removed. The lungs being one of those areas then function to remove the gases (specifically carbon dioxide and excess oxygen) so they can be exhaled.

If inhaled, asbestos in air can scar lung tissue.

The lungs extract oxygen from the atmosphere for body cells to use.

These are called alveoli. The singular term is alveolus.

Your lung is totally elastic organ. If air enters the pleura, lung will contract. It will be useless for respiration in such case. You have to put under water seal to take out the air from the pleura. If air happens to enter in both of the pleura, you will die in 5 minutes.

If the question is "What makes the Lung expand?" then the answer is the Diaphragm. Located below the lungs, the diaphragm pulls down on the lungs causing them to increase in volume and in turn causing a lower pressure than that outside the body. This causes air to enter the lungs.

If the question is "What makes the Lung grow?" then the answer is the indeed: Time.

I am the executor of my mother's estate. When she passes away, I am the one who has to see that all of her debts are paid, buriel is taken care of, who she owes, notifying all creditors, etc. about her death. Making sure Social Security is notified. Each beneficiary is entitled to a full accounting of what the distribution of the estate is. The Executor is responsible for meeting all the requirements of the probate court and providing full documentation and valuation to the court.

Pneumocyte. There are two types: Type I cells make up the lining of the air sacks (alveoli) in the lung, type II cells produce a slick liquid called surfactant that helps coat the alveoli and keep them from collapsing when we exhale.

no

No it is not connected directly but you are getting oxigen that travels in blood stream from your lungs to brain.

the difference is a toad has four

and a frog has six

please do not listen to this, you are to gullible if you believed this :]

intra pulmonary pressure

think of sympathetic nervous system as 'normal'. The parasympathetic nervous system kicks into action when there are unusual changes within the body. If you are scared for example, or if you take a drug or are unwell due to a bug. The parasympathetic nerve widens pupils, makes you go to the toilet more often, increases heart rate, widens bronchia etc. hope this helps. Not all these things will happen with all drugs or all illnesses, just using these as a brief example.
