Lungs

Yes. In time - especially if you are not religious about taking the right doses of the right drugs at the right times - HIV can develop resistance to the drugs used to treat HIV. This is one of the reasons why HIV-positive patients receiving treatment are advised to have regular blood tests - the blood tests enable doctors to monitor the continued effectiveness of the treatment. If you develop resistance to one or more of the drugs you are being treated with, then other drugs will be substituted in to your treatment regimen to bring the infection back under control. Taking your drugs in exactly the manner prescribed - in the right dose, at the same time, EVERY single day, with or without food - ensures that the right levels of the drugs are maintained at all times. Doing this is the single most important thing you can do to keep the virus firmly under control and avoid developing resistance to your drugs .. it is generally when the levels of the drugs fall below therapeutic levels that the virus gets the opportunity to mutate and develop resistance.

no, it only rots your teeth! :)

Bronchioles..

Air goes into or out of the lungs due to differential pressure. On inhalation, the pressure within the lungs is below atmospheric, so outside air rushes in. On exhalation, the pressure within the lungs is above atmopheric, so inside air rushes out.

When you stop breathing for the moment at the end of exhalation, or when you transition from inhalation to exhalation at the end of inhalation, there is no air flow, because there is no differential pressure. Assuming that you do not close your larynx, then, when the lungs are at rest, the air pressure in the lungs is the same as atmospheric, and this occurs twice in each complete breathing cycle.

There are many good websites that you can buy these great bone building supplements. You might want to try : www.amazon.com or another good site is: www.onlinecoralcalcium.com/ they have a lot to choose from and fair shipping prices.

parietel pleura

oxygen

Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.

it is called the avoile

Red Blood Cells

air sacs

There are several: the ribs, the thoracic vertebrae and the sternum. Together they are called the rib cage.

Air rushes into your lungs until an equilibrium of pressures is achieved.

Yes

Your venous system certainly falls in the category along with your arterial system.

The lungs don't have cartilage as such, the main "tubes" into the lungs have bands of muscle and cartilage to give them structure, because the lungs are very wet as they are covered in mucus if there was no support they would stick together and be held shut by surface tension (have you ever put a wet saucepan lid on to a work surface and couldn't remove it? same principle) if the tubes were stuck shut obviously you wouldn't be able to breathe :/

It depends on your age, but 10 litres is a VERY good lung capacity for an adult. For a child, 10 litres seems ridiculous because the average is 2 litres.

pretty sure its a pinkish color, same as when your older. (unless you smoke that is)

It is called the Diaphragm, which is under the lungs and rib cage. ---- The Diaphragm is what moves the rib cage up and down when you breath in and out.

Excretion is the process of removing metabolic wastes. In the lungs, oxygen diffuses in to the capillaries, and carbon dioxide, a byproduct of cellular respiration, diffuses out. This makes CO2 the lung excretion.

Perform negative pressure check.
