The arifact that I chose is the "How Big Are Your Lungs" Activity, as it is specifically related to the respiratory system, of the internal system unit. The respiratory system is a important system, as the blood recives oxygen and releases the waste that includes carbon dioxide out of the body which exits through the nose. As the respiratory system is a key factor for humans as the cells in the body needs oxygen in order for them to survive. The respiratory system is also important for humans because this internal system helps control the amount of oxygen that enters the brain, as this is the most important organ in the human body. If the brain lacks a minute without oxygen, the person can easily pass out. The reason why I chose this artifact because it's a great example of showing what happens during inspiration and expiration, while breaking in and out. 

 

The artifact was an activity in class called "How Big Are Your Lungs." The objective of this activity is to measure your tidal volume and vital capacity. Then you are to compare your results to a theoretical number based on an equation. What I have learned from this activity is that I have a better understanding on how Inspiration and Expiration Works. Before blowing the balloon, we breathe in, as the diaphragm flattens out and contracts. Since the diaphragm is going down, it gives it enough room for your lungs to grow larger as they fill up with air, as your rib muscles also moves up, to give your lungs space as well. As you are inhaling the air goes through your mouth and nose, where the air then goes down your trachea. As it goes down, tiny hairs known as cillia moves gently, so it can keep mucus and get the dirt particles out of your lungs. The air then goes through a series of branches in your lungs, then through the bronchi and bronchioles. When you are about to blow into the balloon, our diaphragm moves up, pushing air out of the lungs, as your rib muscles also becomes relax and moves back in. As the cells in your body has used the oxygen that was needed, and the blood is know getting rid of the carbon dioxide and other wastes. The air goes through the bronchioles, then the bronchi, the trachea and finally through your mouth, to fill the balloon up with air. 

 

The significance of this artifact is to determine how effective are your lungs. The significance of knowing this is that, your lung effiency tells you a lot about your health and fitness. As the stronger your lungs are, the more air you are able to exhale, and they also have a better overall performance. Your muscles need to receive oxygen, in order to run, cycle, hike or perform any type of aerobic movements. As everyone's lung capacity is different in every human. As their are many factors that can affect your breathing such as base on your height and also where you're obese or not. This is significant for me because now I can know what I can do to increase my lung capacities, to make sure to have a better overall lungs. It's important for me to know that excircising, walking, or running can be helpful to increase the efficency of your lungs. As excircising, increases the strength in my muscles around my lungs. Doing excircise can result in having a higher blood volume, as I'm able to carry more oxygen more quickly to my muscles. Therefore, increases my lungs. Eatting healthier foods and being physically active is key to increasing your efficency in your lungs.

 

The knowledge from this activity is going to be helpful for many students to make better lifestyle choices. In North America, in teenagers and young adults, we can clearly see that they are constantly choosing negative lifestyle choices that affects their lungs, which make's it harder for themselves to breathe. The experiences and knowledge gain from this activity, just as stated before in the previous paragraph, students are encouraged to excircise more and eat more healthy foods, which can increase your lungs efficency. Avoid the following things to increase your lung capacity, first off smoking. Smoking is bad for the human body, especially for the respiratory system, as it prevents the exchange of Oxygen Gas And Carbon Dioxide Gas. Thus, making it harder everytime for you to breathe or do any physical activities. It's also good to practice breathing deeper, breathing in fully and exhaling completely, can result into having a more effective body to process oxygen and to carry out to your cells. Taking your vitamins are essentially important to help have a better functioning lungs. Taking vitamin A, C and E or can also be found in certain foods such as eggs, mushrooms and meat can help your lungs.

 

In conclusion, the respiratory system is important for keeping the body function properly. This activity helped me have a better understanding on how inspiration and expiration works. Also it help me realize that, there are ways to increase your lungs efficency by doing excircise and avoid choosing negative lifestyle choices such as smoking. As the respiratory system helps cells that needs oxygen and also releases waste and carbon dioxide from the body.
