After air has passed down the trach

After air has passed down the trachea to the lungs, it enters two branches: one branch enters the right lung and the other branch enters the left lung. These two branches are called primary bronchi. One branch is called a bronchus.
Bronchi also have cartilage around them, but the amount decreases as the bronchi extend in to the lung. Soon after the primary bronchi enter the lungs, each bronchus branches again. These new branches are called secondary bronchi. Each secondary bronchus enters into one of the lobes (parts) of the lung. There are three lobes in the right lung and two lobes in the left lung. Thus there are five secondary bronchi. In the lobes of the lung, the secondary bronchi branch into tertiary bronchi (tert - means three)
The tertiary bronchi within the lung branch into small tubes called bronchioles. Although these bronchioles are quite small in diameter, they are very important in regulating the amount of air that enters the lungs. The bronchioles have a thin layer of smooth muscle that contracts when less air is needed and dilates when more air is needed.
Eventually, the air that is carried by the bronchioles enters clusters of alveoli. Alveoli are very tiny bubbles with very thin walls. One individual "bublle" is called an alveolus. Alveoli cluster around a bronchiole, just like grapes cluster around a stem; therefore, all alveoli in a cluster connect with a single bronchiole. The alveoli are where the blood drops off carbon dioxide anf picks up oxygen. Your lungs are packed with them.
In fact, each lung contains about 150 million alveoli. Despite all of the tissues yor lungs contain, they are very lightweight. They resemble a sponge.
The walls of each alveolus are comprised of elastin fibers. Recall that elastin is also found in skin. Elastin allows skin as well as the wal of each alveolus to stretch when you breathe in and return to its original size when you breathe out.

After we passed down the windpipe to the lungs, it goes into two branches: one branch in the right lung and the other branch to the left lung. Branches second title in French is the main bronchi. A detailed branch is called a bronchoscopy. bronchial cartilage around them also, but the number decreased as the bronchi in the lungs to expand. Immediately after the main bronchi in the lungs, bronchi each branch again. The new branch name in French is secondary bronchi. Each bronchial High School into one of the lobe (section) of the lung. not have three lobes of the right lung, two lobes of the left lung. therefore , there are five secondary bronchi. lobe At the lungs, the bronchi branch into secondary bronchi tertiary (tert - meaning three) The tertiary bronchi in the lungs branch into smaller tubes called bronchioles. Wearing whether the bronchioles is quite small diameter, they are very important in regulating the amount of air into the lungs. bronchioles with a thin layer of smooth muscle that contracts when the machine is less than is necessary, and stretching when gas is needed necessary. Finally, the air is done by the bronchioles into alveolar clusters. Discarded capsule is very small bubbles with very thin walls. An individual "bublle" is called an alveolus. alveoli clusters around the city bronchiole, like grape clusters around a tree, so that all the alveoli in a cluster connected to a single bronchiole. alveoli are where the blood drops off carbon dioxide anf pick up oxygen. lungs you are packed with them. In fact, each lung contains about 150 million alveoli. Though all yor lung tissue contain, they are very light. they look like a sponge. walls of each alveolus is including elastin fibers. Recalls also found that elastin in the skin. Elastin allows skin as well as wal each alveolus to lengthen as you inhale and return to its original size when you exhale.

After the air has been passed down the windpipe to the lungs, it goes into two branches: one branch goes to the right lung and the other branch goes to the left lung. Both branches are called the bronchi. A detailed branches called bronchi.
bronchial cartilage around them also, but the amount decreases with prolonged bronchitis in his lungs. Immediately after the main bronchus enters the lung, each bronchus branches again. The new branch called secondary air management. Each secondary bronchus goes into one of the lobes (parts) of the lungs. Having three lobes on the right lung and two lobes in the left lung. Hence there bronchial year. In lobes of the lungs, the bronchi branch into tertiary bronchi medium (tert - meaning three)
The tertiary bronchi in the lungs in small tubes called bronchioles. Though quite small bronchioles road glass, they are important in regulating the amount of air going into the lungs. The bronchioles have a thin layer of smooth muscle contracts when less air is needed and dilating when more air is needed necessary.
Finally, the air is done by going into the bronchioles alveolar clusters. Discarded capsule is very small bubbles with very thin walls. An individual "bublle" called alveolus. complex waste capsule surrounding a bronchiole, like grape clusters around the stem, so that all the alveoli in a cluster connected to a single bronchiole. alveoli where the descending blood carbon dioxide and oxygen picked patience . Lungs of you is packed with them.
In fact, each lung contains about 150 million alveoli. Though all yor containing lung tissue, they are very light. They are like a sponge.
walls of each alveolus included elastin fibers. Recalls elastin are found in the skin. Elastin allows skin as well as wal each alveolus to stretch when you inhale and return to its original size when you exhale.
