Why lungs are important for our health?

Every cell in your body needs oxygen to survive. The air we breathe contains oxygen and other gases. Peptide Therapy In Los Angeles, CA Once the oxygen reaches the lungs, it moves into the bloodstream and passes through your body. For every cell in your body, oxygen is converted into a waste gas called carbon dioxide. The bloodstream then returns this lost gas to the lungs where the blood flow is removed and then inhaled. Your lungs and the respiratory system automatically perform this important function, called gas exchange.

In addition to gas exchange, your respiratory system plays other important roles in breathing. These include:

Bring the air to the proper body temperature and humidity at the appropriate humidity level.

Protect your body from harmful substances. This is done by coughing, sneezing, filtering or swallowing.

Support your sense of smell.

Parts of the Respiratory System and how they work


The sinuses are gaps in the bones of your head above and below your eyes that are connected to your nose by small holes. The sinuses help regulate the temperature and humidity of the inhaled air.

The nose is the preferred choice for air outside the respiratory tract. The hair that covers the nasal passages is part of the air filtration system.

Air also comes out of the mouth, especially for those with menstrual cramps, whose nasal passages may be temporarily blocked by a cold, or during strenuous exercise.

The throat picks up the inhaled air from your nose and mouth and passes it to your windpipe.

WINDPIPE (windpipe) is the passageway from your esophagus to your lungs.

The air sac divides into two large bronchial tubes, one for each lung, and again each box divides for your lungs. These, in turn, expand into the bronchioles.

Lungs and Blood Vessels

Your right lung is divided into three lobes, or parts. Each umbilical cord looks like a balloon filled with sponge-like tissue. Air enters and exits through one opening – a branch of the bronchial tube.

Your left lung is divided into two processes.

PLEURA is a double membrane, in fact, a series of folds, surrounding each membrane of the lungs and separating the lungs from your chest wall.

Your bronchial tubes are connected to CILIA (like very short hair) and move like waves. The activity takes mucus (carrying mucus or fluid) and into the throat, where it spit-ups, coughs, or swallows. Mucus picks up and holds most of the dust, germs, and other unwanted substances that have invaded your lungs. You will get rid of this by coughing, sneezing, clearing your throat, or swallowing.

The smallest branches are called bronchi, and their ends are air sacs or alveoli.

ALVEOLI is a very small air sac in which oxygen and carbon dioxide are exchanged.

Capillaries are the blood vessels in the walls of the alveoli. The blood passes through the arteries, enters the tech and heads towards the sound of the boulmony. While in the arteries, the blood releases carbon dioxide through the walls of the alveoli and takes up the oxygen in the air in the alveoli.

Muscles and Bones

DIAPHRAGM is a hard wall of muscle that separates the lining of your chest and your abdominal cavity. As you go down, suction of the chest occurs, capturing air and expanding the lungs.

The ribs are the supporting bones that protect the lining of your chest. They move slightly to help your lungs expand and contract.

Maintain Lung Health

Lung capacity decreases as you get older. Keep your lungs healthy by taking care of yourself every day. Eat a balanced diet, exercise, and reduce stress so you can breathe more easily.

Factors that Affect Lung Health

There are many things that irritate the lungs, including both indoor and outdoor pollutants. Common lung irritants include:

  • Lead
  • Radon
  • Fire-retardants
  • Formaldehyde
  • Cleaning agent vapors
  • Mold
  • Pet dander
  • Dust mites
  • Pollen
  • Carbon monoxide
  • Secondhand smoke
  • Ozone or smog
  • Particulate matter
