what is the nameof the membrane that covers the lungs?

Its called the pleura, I found it for you on a cancer website-lol hope this helps

pulmonology text would have it.  find it at your local medical school.

For example, the lungs and small intestine contains microvilli.  Another example, the brain and intestine also are folded.

The lungs excrete carbon dioxide (a waste product from metabolism)

The first is surface area. The mammalian lung has a huge number pf alveoli compared to lung structures of reptiles and amphibians. The greater the surface area available for gas exchange, the more efficient will be the gas exhange.\n\nThe second requirement for gas exchange is assisted by the mamallian heart of four chambers as opposed to reptilian and many other hearts. There is an enormous amount of the circulatory system that passes directly to the pulmonary arteries and veins. Thus there is sufficient blood circulation in the lung area to remove oxygen and transfer it to the rest of the body.\n\nComparative biology will show far fewer alveoli in non-mammalian hearts (with the exception of birds). The other thing notable from compataive anatomy is that the mamallian heart (and that of birds) is a four chambered pump that does not mix unoxygenated blood with blood that has been oxygentated.\n\nSurface area and increased opportunities for deoxygenated hemoglobin to accept oxygen due to more efficient heart action.

Air travels to the lungs through a series of air tubes and passages. It enters the body through the nostrils or the mouth, passing down the throat to the larynx, or voice box, and then to the trachea, or windpipe. In the chest cavity the trachea divides into two branches, called the right and left bronchi or bronchial tubes, that enter the lungs.\n\nIn the adult human, each lung is 25 to 30 cm (10 to 12 in) long and roughly conical. The left lung is divided into two sections, or lobes: the superior and the inferior. The right lung is somewhat larger than the left lung and is divided into three lobes: the superior, middle, and inferior. The two lungs are separated by a structure called the mediastinum, which contains the heart, trachea, esophagus, and blood vessels. Both right and left lungs are covered by an external membrane called the pleura. The outer layer of the pleura forms the lining of the chest cavity.\n\nThe branches of the bronchi eventually narrow down to tubes of less than 1.02 mm (less than 0.04 in) in diameter. These tubes, called bronchioles, divide into even narrower tubes, called alveolar ducts. Each alveolar duct ends in a grapelike cluster of thin-walled sacs, called alveoli (a single sac is called an alveolus). From 300 million to 400 million alveoli are contained in each lung. The air sacs of both lungs have a total surface area of about 93 sq m (about 1000 sq ft), nearly 50 times the total surface area of the skin.\n\nIn addition to the network of air tubes, the lungs also contain a vast network of blood vessels. Each alveolus is surrounded by many tiny capillaries, which receive blood from arteries and empty into veins. The arteries join to form the pulmonary arteries, and the veins join to form the pulmonary veins. These large blood vessels connect the lungs with the heart.\n\n© 1993-2003 Microsoft Corporation.

We have tiny little air sacs that make up our lung tissue. They're called "alveoli" (each one is an "alveolus"). In order to work properly, they need to maintain elasticity. It's also important that the walls of the sacs maintain their structural integrity. Cigarette smoke, air pollution, and some genetic conditions will cause the walls of the alveoli to harden or to lose their elasticity and for the individual sacs to collapse. If that happens, the surface area where oxygen can enter the bloodstream through the alveoli decreases. \n\nThis isn't a perfect analogy, but think about it this way: if you're trying to blow up a balloon, but you pinch the opening too tightly, you won't be able to get air into the balloon (your bloodstream). What you're doing there is decreasing the "surface area" of the hole. At a certain point, you won't be able to get any air in the balloon at all - or at least not enough to beat the resistance of the tension of the inner walls of the balloon. \n\nWith emphysema, as the disease progresses the person can't get enough oxygen through the walls of the alveoli and into the bloodstream to sustain life, and eventually asphyxiates. Even with increasingly pure doses of inhaled oxygen, the lungs lose their capacity to oxygenate the blood.\n\nAlthough emphysema isn't curable, lung transplantation offers some hope. Also, its progress can often be arrested by quitting smoking, reducing pollutants in one's environment, and by use of some steroids (some of which have very severe side-effects, though).

The kidneys . They discard electrolytes through a membrane that the body doesn't use such as uric acid and keep those that the body uses like water. Other filters in the body are lungs, skin, liver,  and spleen

It works with each heartbeat.  The gas moves with each heart beat. The area of the lung where the blood takes the gas is called the A/C membrane (Alveolar/Capillary) the membrane is so thin so the gas can diffuse into the blood.

First the diaphragm under the lung expands creating an area of low pressure in the lungs leading to the air from outside the body to rush into the mouth to the trachea to the bronchi to bronchi oles and then to alveoli. The lung is like a sponge and has an increasingly small system of tubes that are lined with microscopic alveoli that are lined with capillaries. When O2 molecules reach the alveoli they diffuse oppositely to carbon dioxide which is the body's waste gas. The blood cells go from the capillaries in the alveoli to venules to the pulmonary vein where it enters the left atrium and then goes to the left ventricle where it is rushed out of the heart through the aorta where it divides into other arteries, arterioles, and then capillaries.

Lung is a special organ which allows gas exchange. Air passes through trachea, bronchi, bronchioles and finally alveoli. Oxygen will diffuse form the alveoli into the blood plasma whereas the diffusion of carbon dioxide occurs in opposite direction.

The alveoli spread into branches called arbor vitae.\nthe alveoli are present in your lungs and help in exchange of gases(oxygen and carbon di oxide)

Nuclear?  Nuclear envelope?  Nuclear membrane? \n\nThe word 'eukaryote' means 'true nuclei'.  They are talking about the membrane which surrounds the nucleus of the cell.  This is not present in Prokaryotes.
