= __The Respiratory System- Functions __ =

The respiratory system moves oxygen from the outside into the body along with [|carbon dioxide] and water. Did you know that respiration is different from breathing? Respiration is the chemical reaction of energy releasing in the dells to burn fuel with the oxygen. Respiration is vital since if you don’t breathe, your cells don’t have energy, so you die. How respiration works is this; air goes through your nose or mouth, down you pharynx or your throat, while a little flap called the epiglottis covers the entrance to your stomach, so you don’t breathe in food or swallow air ([|choking]). The air goes down your trachea, and into your lungs. In your lungs there are tubes branching out called bronchi. Bronchi get smaller and smaller. The tiniest ones are called bronchioles that have little air sacks called alveoli attached to the ends of them. The alveoli have [|capillaries] on them that take the good air into the blood and the CO2 into the lungs to exhale. The ribs cover your lungs to protect them. The lungs expand because the diaphragm (a large, dome shaped muscle) pushes them as it goes upward. When it relaxes and goes back down, the lungs contract, and you exhale.

=** __The Respiratory System- Organs __ **= There are many organs in the respiratory system. The first one is the lungs. They are located below the trachea and they help you suck in air. When you breathe in, the air goes into your lungs. Next up is epiglottis, which is a flap in the pharynx that blocks the entrance to the throat. It’s the trachea! The trachea is where all the air goes. Air travels to your trachea after going through your pharynx, which is next. The pharynx is the throat. It shares with the digestive system: the nose and the mouth. The Larynx is your voice box. The more air you force out, the louder the sound you make will be. Your diaphragm is a dome shaped muscle that, when inhaling, pushes the lungs so they expand, and when you exhale, relax.

= __The Respiratory System- Neighbors __ = The respiratory system collaborates with many others, including the digestive system, immune, excretory, and endocrine, but not skeletal. The respiratory system works with the digestive system because the pharynx is connected to the mouth and nose. The immune system plays a part because when dust or germs get into your lungs, you cough, which is part if the immune system to get rid of unhealthy things in your body. Excretory and respiratory both, in some way or another, get rid of [|cellular waste], pee- or CO2 for the lungs. The endocrine system works with the respiratory system because when your adrenal glands (endocrine) start working, your bronchi open up for more air (respiratory). It makes you breathe harder, so, for example, you can run faster when a dog is chasing you.

= __The Respiratory System- Health and Diseases__ =

The respiratory system is armed for enemies. Diseases come in the form of lung cancer, asthma, and many more. These can be dangerous like lungs cancer caused by smoking, or less dangerous like asthma. There are, however, ways to defend the respiratory system and its organs. First things first: don’t smoke! The black, sticky tar in the [|cigarette] settles in the lungs clogging up the airways and making us cough.But there isn't just tar. Here is a list of the **[|599 ingredients]**in a cigarette. The tar also sticks to cilia, preventing them from moving back and forth and getting dust and mucus out of our throat. Smoking breaks down alveoli making it harder to breathe. Finally, cigarette smoke makes the good cells go away and the bad cells stay, and makes your pink, healthy lungs go black and icky. To avoid this and bad lungs, exercise! Exercising makes your heart beat faster. This lets your lungs get better and stronger. Lastly, try not to breathe in pollution. It has a similar effect on your lungs as smoking, damaging them. Wear a mask over your mouth if you bike on roads so you don’t breathe in car gas.
