Environmental conditions such as pollution and smoke could permanently damage the alveolar sacs.
A protein called hemoglobin present in red blood cells is able to bind oxygen molecules. Capillaries surround the alveolar sacs in the lungs where oxygen diffuses into the blood where it is bound by hemoglobin. Now, the oxygen is in the blood.
The air sacs are called Alveoli
Blood capillaries surrounding air sacs called alveoli.
Water can dissolve rocks because the water will slowly soften up the rocks and then after a while the rocks will eventually dissolve, they dissolve because they are in water for a while and then they will wear off and dissolve slowly.
okay do you mean cycle of breathing and stuff look:You probably breathe about 20 times every minute. If you are running or playing hard, you might take 80 breaths a minute.When you inhale air through your nose or your mouth, that air takes off on an incredible journey. First it goes down the back of your throat, past your voice box, and into your windpipe, or trachea. Your trachea is like a tunnel that branches off into two more tunnels called BRONCHIAL tubes or BRONCHI. Each bronchial tube goes off to one of your lungs. It doesn't matter whether the air goes to the right lung or the left lung. Both lungs do the same job...Inside your lungs, the bronchi are like upside-down trees. They split into smaller and smaller branches and then into many twigs. The twigs end in tiny air sacs called alveoli. So far, the air has just been along for the ride. Inside the alveoli the air really goes to work. Its job is to keep us ALIVE!The job of the air in your alveoli is to bring oxygen into your body and take carbon dioxide out. Oxygen and carbon dioxide are two invisible gases in air. The secret to doing this job is BLOOD .The air in your alveoli sends oxygen into your blood. Your blood flows through a system of tubes called blood vessels. First, blood full of oxygen goes to your heart. Your heart is like a big pump. It sends the oxygen-filled blood whooshing off to all parts of your body.The blood vessels that deliver oxygen are called arteries. Arteries branch off into smaller and smaller tubes. The tiniest blood vessels are called capillaries. Capillaries reach every cell in your body and drop off the oxygen. In your cells, the oxygen works with food to make energy for you.P.S: I am sorry I just know this!!!
Pollution and smoke
Coal dust, silica dust, and asbestos, which may lead to pulmonary fibrosis

Alveolar sacs is the structural unit of lungs.Tiny blood capillaries fuse together to make up an alveolar sac.This structure of the sac is very important for the easy diffusion of respiratory gases across the membrane.
Respiratory bronchioles end in alveolar sacs (alveoli).
Simple Squamous
Hyper inflation of air sacs with destruction of alveolar walls.
The respiratory looks like an upside down tree, from the trunk to the branches and to fruit (such as an apple). From largest to smallest, the respiratory system consists of the throat to main bronchi, to bronchioles, to terminal bronchioles, to alveolar ducts, to alveolar sacs (aveoli look like tiny grapes).
Air filling the alveolar sacs.
Simple Squamous
Alveolar means pertaining the the alveolus (plural alveoli), the small air sacs in the lungs.
Alveolar volume is lung capacity. Alveoli are the air sacs in the bronchioles. How much air the lungs hold during both inspiration and expiration is lung capacity which is alveolar volume. Hope this helps
