why do we need the respiratory system

What do you need to do to each and every day here on Earth? If you're like most kids, eating and drinking are the two things that probably come to mind first. However, there's one other important thing you need to do
to. What are we talking about? Breathing, of course! We do it so often Б and without thinking Б that it's easy to forget about. We can go days without water and possibly weeks without. We can't go minutes without, though! But why is that? What does breathing serve? The importance of breathing is linked directly to the importance of one particular element your body needs : oxygen. When you inhale, a large muscle called the flexes downward to help air into your lungs. Your lungs are one of the largest organs in your body. They work together with the rest of your system to keep your body's cells supplied with necessary oxygen.

If you put your hand on your chest, you can feel it expand and contract as you inhale and exhale. That's the power of your lungs working together with your to bring air into and out of your body. As you breathe in air, it travels through large tubes in your lungs called bronchi. The bronchi branch off into many smaller tubes called bronchioles. You have about 30,000 bronchioles in each lung. At the end of each bronchiole are clumps of extremely air sacs called. How small are? Very small! So small, in fact, that there are about 600 million of them in your lungs! The in your lungs are covered with called. It's there, in your, that the oxygen in the air you breathe passes into your blood the. From your, the blood travels to the heart, where it's pumped out to the rest of the cells in your body.

Your cells need oxygen to convert the nutrients you eat into energy for your body. In the process of making that energy, some waste products are produced. One of the main waste products is a called carbon dioxide. Your body needs to get rid of carbon dioxide, so what does it do? It breathes it out! That's right! Not only does breathing provide your body with necessary oxygen, but it also rids the body of waste like carbon dioxide. To get rid of carbon dioxide, your delivers it to the your. In the, the carbon dioxide moves into the lungs, where it leaves the body when you exhale. Exhaling occurs when your flexes upward to push air out of your lungs and back into the air. Your respiratory systemвs primary function is to breathe in air, absorb oxygen into the bloodstream, and breathe out carbon dioxide.

We are all born with the same equipment that does the same thing, but some of us end up, for whatever reason, needing a little help. First off, letвs take a look at how the lungs and airways work. Then we can understand the different kinds of diseases that can cause problems for us down the road. Air comes into the body through the nose or mouth, and enters the airways. are the tubes that carry air into our lungs. As they branch out, they become smaller and smaller, and eventually connect to small air sacs where fresh oxygen from the air is exchanged for carbon dioxide in the blood. This oxygen is then taken through the blood to the rest of your body, where it is used to produce energy. How does the Respiratory System work? Trachea This is your main windpipe, which starts at the back of your throat.

Bronchi You have two of these, a left and right one that split off from the trachea to feed each lung. Bronchioles These tiny tubes branch off from the bronchi, extending throughout all of your lungs. Alveoli These are the tiny air sacs that connect to each bronchiole. Blood passes through here, exchanging fresh oxygen from the air for carbon dioxide to be carried back out and exhaled. Diaphragm This is your primary breathing muscle, located at the base of your chest. People who suffer from chronic lung disorders have something wrong with one or more parts of this system. This prevents their lungs from working properly, and as a result, prevents their body from getting the oxygen it needs to function properly. If you or a loved one have a chronic lung disorder and require, you may benefit from using a.
