what causes fluids to go into the human lungs?

It is the infection of lungs or the membrane covering them.

The fluid that accumulates in the lungs due to trauma or disease is termed pleural effusion commonly known as “water of the lungs.”There are two thin membranes in the chest, one lining the lungs(the visceral pleura) , and the other covering the inside of the chest wall(the parietal pleura). Normally, small blood vessels in the pleural linings produce a small amount of fluid that lubricates the opposed pleural membranes so that they can glide smoothly against one another during breathing movements. Any extra fluid is taken up by blood and lymph vessels, maintaining a balance. When either too much fluid forms or something prevents its removal, the result is an excess of pleural fluid–an effusion. The most common causes are disease of the heart or lungs, and inflammation or infection of the pleura. Pleurisy, also called pleuritis, is an inflammation of the pleura, which is the moist, double-layered membrane that surrounds the lungs and lines the rib cage. The condition can make breathing extremely painful, and sometimes it is associated with another condition called pleural effusion where excess fluid fills the area between the membrane’s layers. The double-layered pleura protects and lubricates the surface of the lungs as they inflate and deflate within the rib cage. Normally, a thin, fluid-filled gap — the pleural space — allows the two layers of the pleural membrane to slide gently past each other. But when these layers become inflamed, their roughened surfaces rub painfully together like two pieces of sandpaper with every breath, sneeze, and cough. In some cases of pleurisy, excess fluid seeps into the pleural space, resulting in pleural effusion. This fluid buildup usually has a lubricating effect, relieving the pain associated with pleurisy as it reduces friction between the membrane’s layers. But at the same time, the added fluid puts tremendous pressure on the lungs, reducing their ability to move freely and causing shortness of breath. In some cases of pleural effusion, this excess liquid can become infected.

different ways, you could get 1.pneumonia usually viral or bacterial or rarely mycoplasmal, which causes inflammation in the lungs, the alveoli (air sacs) fill with pus and fluid (of course this can be very dangerous since this is where gas exchange takes place) 2. congestive heart failure, where fluid accumulates in the lungs because the left side of the heart can’t keep up with the right side. 3. heart attacks, any caridomyopathy , leaking or damaged valves (aortic and mitral) can all result in higher pressures in the heart, this pressure forces fluid into the lungs and into the alveoli (which makes people tired and short of breath). 4. direct injury to the lungs from too much intravascular fluid (in someone with kidney failure), heat, blunt force to the chest, poisonous gas, lots of reasons.

Tuberculosis, which is caused due to climatic conditions.

Very many things. Don’t even know where to start man.

i think what you’re referring to is a condition called pulmonary edema. it happens when there is excess fluids (water retention)in the body (resulting from many conditions — from inflammation, to burns etc.) however the heart cannot pump all those fluids out so some of them backs up in the left ventricle, to the left atrium, then backs up to the lungs — and that’s how somepeople get pulmonary edema.therapy for it is to put a patient under diuretic therapy so that he/she can urinate all those fluids out. otherwise, pulmonary edema is not the only condition that we are concerned about, but all these fluids can actually cause heart failure

Fluid can accumulate in different ways. First there is always some small amount of fluid in your lungs at all times, it usually works it way up and out of the lungs, where we either spit it out or swallow it. Another way, is with CHF/ Congestive Heart Failure. CHF is a process in which every time the heart beats, a small amount of fluid backs up into the lungs. Some people can live with this for years/ decades, others will progress to the point where so much fluid gets backed up into the lungs that they actually drown on their own fluids.
