Where In The Respiratory Tract Is The Air Filter

Lungs: How They Work

The right lung has 3 sections called lobes and is a fiddling larger than the left lung, which has 2 lobes. The bronchial tubes separate into smaller air passages called bronchi. The performance of the lungs is discussed in detail.

How Your Lungs Piece of work

How do my lungs work?

Your lungs make oxygen available to your body and remove other gases, such as carbon dioxide, from your body. This procedure takes place 12 to xx times per minute.

When you inhale through your olfactory organ or oral fissure, air travels down the pharynx (back of the throat), passes through your larynx (vocalism box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung. For the lungs to perform their best, the airways demand to be open during inhalation and exhalation and need to be complimentary from inflammation (swelling) and abnormal amounts of mucus.

The correct lung has three sections called lobes and is a fiddling larger than the left lung, which has 2 lobes. The bronchial tubes dissever into smaller air passages called bronchi, and so into bronchioles. The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood.

Lungs, Bronchial tube, Alveoli and Cilia

After absorbing oxygen, the blood leaves the lungs and is carried to the heart. The blood then is pumped through your body to provide oxygen to the cells of your tissues and organs. When cells apply oxygen, carbon dioxide (CO 2 ) is produced and transferred to the blood. Your claret carries the CO 2 back to your lungs and it is removed when you breathe.

Your respiratory organisation prevents harmful substances from entering the lungs by using:

Pocket-size hairs in your nose act as an air-cleaning arrangement and assist filter out large particles;
Mucus produced in the trachea and bronchial tubes to continue air passages moist and assistance in intercepting dust, bacteria and other substances;
The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean. If substances such equally cigarette smoke are inhaled, the cilia end operation properly.

Healthy lungs are fabricated of a spongy, pink-greyness tissue. Lungs that accept become polluted with harmful carcinogens (substances that cause cancer) or carbon particles appear to have blacked spots on the surface. Healthy lungs are rubberband then they can aggrandize when you exhale. In contrast, a disease like emphysema causes the lungs to lose their elasticity.

When a person's lung can no longer expand properly or transfer oxygen to the blood, that person has difficulty breathing and tires hands.
