= Functions =

There are many systems in the human body, but the respiratory system is the system that helps you breathe. The respiratory system brings new fresh air and oxygen (O2) into your body. It also brings O2 into your blood. Another function is that the [|respiratory system] takes carbon dioxide (CO2) and other wastes out of your body. The oxygen comes in your body and through the lungs, then it goes into your blood and to the cells and into the mitochondria to convert sugar into cellular energy. Your mitochondria uses the oxygen to bond with hydrogen to form water, which is a waste product of respiration. The respiratory system brings fresh new air in, and expired air filled with CO2 and water out of the body. Without the respiratory system we wouldn’t have a way for our cells to get oxygen or rid our cells of COD and water, H2O.

We need the respiratory system because without it we wouldn’t be alive. The respiratory system gives our blood oxygen so that it is nice and healthy. The respiratory system takes all the CO2 from our blood and brings it out of our body. Also, it brings oxygen from the air and into our mitochondria which makes energy for your body. When you inhale the air enters your body through your nose and mouth and down the trachea. The trachea cleans out the air during the journey. Then the air goes to the bronchi and goes into your lungs. They split into many bronchioles, at the end of the bronchioles there are alveoli. Alveoli are small air sacks with thin walls, the air goes straight through them and into the blood. Each organ has something unique about it. To watch a video click [|here.]

= Organs =

Each and every organ in the respiratory system has it s own job.The bronchioles are tubes as thin as a SINGLE strand of hair and there is 30,000 in each lung. The bronchioles clean the air and bring it to the alveoli. Alveoli are air sacks that have very thin walls and are covered with capillaries. You have 600 million in your lungs. The air passes right through them and into the capillaries. If you cut all your alveoli open it would cover an entire tennis court. Your right lung is divided into 3 parts and your left lung is divided into 2 parts. Your lungs hold the air in your body when you inhale and exhale. They also carry other organs that work in the respiratory system like bronchioles and alveoli. Your right lung is bigger than your left lung. That is because your heart is on the left side and it needs room so your left lung is smaller. The respiratory system also works with other systems in your body.

= Systems My Systems Work With =

The respiratory system also interacts with many other systems in the human body. One system my system works with is the circulatory system. The respiratory system gives oxygen to the blood which the circulatory system brings through your body. The circulatory system brings CO2 into your lungs which brings it out of your body. My system also works with the muscular system. Inside a lot of organs is smooth muscle. And smooth muscle then works with the respiratory system. The heart is cardiac muscle, and my system works with the heart. Another system my system works with is the nervous system. Your nerves send messages to your brain which tells your lungs when to expand and contract. The respiratory system also works with the skeletal system. Our ribs, which are part of the skeletal system, protect our lungs. When we inhale our lungs expand and our ribs go up and out. We work with many systems, but there are also different health things.

= Health =

The respiratory system also has diseases and health prob lems. One health condition is asthma. Asthma can be caused by cold air, stress, cigarette smoke, infections or allergies. When you have asthma your bronchioles a   re swollen which makes it hard for air to go through. They also produce more mucus and there is inflammation, all of this causes an asthma flare up. Another disease is heart disease. [|Heart dis] [|ease] is caused by cigarette smoke. It makes it hard for the blood to get to your heart. You can also get cancer, lung cancer. Lung cancer is cause by smoking. There are ways to keep it healthy. One way is to exercise. Another way is to not smoke. It is bad for your health and it is expensive. Some people smoke 1 pack a week which adds up to around $234 a year. Other people smoke 1 pack a DAY! That adds up to $1,642 a YEAR!! The respiratory system will always do good things for you. Just make sure you don’t let it do the bad.
