Human lungs are lined with small hairs called cillia, which move foreign bodies and toxic particles out of the lungs, keeping them clean. Nicotine in tobacco smoke causes the cillia to stop working, which in turn causes the lungs to build up with debris, which interferes with the functioning of the lungs. Also, tar from cigarette smoke accumulates in the lungs and prevents the lungs from completely filling with air. Over time, tar and other foreign deposits in the lungs can disintegrate the organs' tissue, preventing normal breathing. The good news is that, once a person stops smoking, the cillia will regenerate and function normally.

∙ 11y agobecause the alveoli will reduce in numbers and will not be as streachy, so the oxygen and carbon dioxide will not be able to pass through easily

∙ 9y agothe chemicals from cigarettes damages the Alveoli so it makes it hard to breathe and our lungs dont work well. Ur Welcome.

What is empheseyma?
Emphysema is a lung condition in which tiny air sacs in the lungs - alveoli - fill up with air. As the air continues to build up in these sacs, they expand, and may break or become damaged and form scar tissue.
Why does the alveoli need such a big surface area in the lungs?
because it needs to move in its own space is well.
Where does oxygen into the blood and carbon dioxide pass out of the blood?
alveoli
Where does gas exchange occur between the lungs and blood?
An alveolus (plural: alveoli, from Latin alveolus, "little cavity") is an anatomical structure that has the form of a hollow cavity. Found in the lung parenchyma, the pulmonary alveoli are the dead ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, which are both sites of gas exchange with the blood as well.
What is the term for the tiny air sacs in lungs?
well.... of course they are called scymeonary pronounced sy meo nary by the way did you know wiki answers mostly are wrong! yep, i know... you are surprised dont use wiki answers or else you will get a F!
What are alveoli surrounded by?
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
What are alveoli?
Alveoli are small air sacs in the lungs, as small as a grain of sand. There are billions of these in the lungs, and the purpose of these alveoli are to supply de-oxygenated blood with a supply of oxygen through gas exchange. They are well-equipped to do this, as well. The first reason is because the cappillaries that the alveoli are supplying with oxygen are spread all over the outside of them, meaning there is more surface area to perform gaseous exchange on. The second reason is because the alveoli walls are only one cell thick, meaning the oxygen only has two cells to go through, the alveoli wall, and the capillary wall.
Three ways in which lungs are well suited for absorbing gases?
The three ways that the lungs absorb gasses are...very moistthe alveoli have a big surface areaand finally...good blood supply
Why don't our lungs work so well if there been damaged by smoking or disease?
Any thing, which is damaged by some reason is not supposed to work effectively, as undamaged things.
What is the sharpest part of the body that could hart you heart?
well if your lungs get damaged then it could hurt your heart very badly.
How does emphysema affect a person's alveoli?
*IT* Doesnt Emphyesma is when alveoli die. how does it affect them... Well it would affect them like it affects every other cell in the body. (decreased O2) but it acually doesnt affect the alveoli it just happens when they die
How can you breathe without lungs?
You can't - lungs are vital organs in humans that a person cannot survive without. We can supplement oxygen to lungs and help extremely damaged lungs function well enough to maintain life (sometimes), but you still have to have lungs to breathe and live.
