Project
For this project my group and I were tasked with making a model to represent both the respiratory and circulatory systems. You can learn about these systems in the power point my group and I made below. Now you may see the model down below and think that this doesn't look like a human body system, and you are right. Our task was to make a model serving the function, not the look. To give a quick summary before the power point basically we used magnets on a treadmill to represent red blood cells and other magnets rolling in to represent oxygen. We would then turn an axle moving the treadmill were then the oxygen magnet would then detach to a cell that is in need of it. We were able to accomplish this transfer since the magnets you see resting on the platform have a much strong force then the ones on the treadmill. This allows the magnets to pull the other magnets off of each other.

Content
The first section of the model represents the Respiratory system. First the oxygen enters the body through the mouth or nose. It goes down the Trachea, into the lungs, and passes through the alveoli to get to the capillaries. Our oxygen is the magnets we are rolling down the ramp. The upper tract contains the Larynx, the vocal cord box. The lower tract has the lungs, which move oxygen into the bloodstream, the trachea is responsible for filtering the air, the bronchi leads the air into the lungs and acts as a passageway, the Alveoli are tiny sacs in the lungs which allow for rapid gaseous exchange, and the Diaphragm which controls the breathing. The Lungs is the part where the oxygen is taken, passed through many tiny air sacs and then diffused through the single cell layer of Alveoli and capillary system. The lungs are made of many specialized cells such as epithelial cells. The oxygen then enters the bloodstream. This is where our body systems work together to perform the task of carrying oxygen to the cell. The conveyor belt is our blood stream and the small magnets attached to the belt are the red blood cells. The oxygen magnets and the red blood cell magnets connect here. The belt turns and the red blood cells carry them to the next section of the model. The purpose of the circulatory system is to move the blood around the body to effectively transport things like oxygen, enzymes, platelets, and white blood cells. Veins, a type of blood vessel, carries the blood from the cells back to the heart. It contain waste gases. While arteries carry oxygen from the lungs to the cells. It contains oxygenated hemoglobin. There are many sizes of blood vessels. The largest of which often have names such as iliac vein. The smallest, called capillaries are in some places only one cell thick. In these places, a exchange of gases between the capillaries and the alveoli takes place. The oxygen diffuses from the oxygen rich air sacks to the oxygen poor blood. Meanwhile, the carbon dioxide and other waste gases travel from the bloodstream to the alveoli. The oxygen is carried mostly on the red blood cells. The blood also contains white blood cells responsible for disease protects, Plasma which carries salt and enzymes, and platelets which form blood clot to stop bleeding. Each molecule of hemoglobin contain 4 Heme molecules. In each is an iron atom. The iron atom can bond with two oxygen atoms. Meaning that each hemoglobin molecule can carry 8 oxygen atoms. The iron gives blood its red color. 97% of the oxygen your body needs is carried on hemoglobin. The other 3% is carried by plasma.
Reflection
For this project my group and I all worked really well together creating this project. Not only did our project succeed, but personally I thought that it was the most original out of them all. Some things that we did well in this was communication, we all voiced our opinions and listened and actually thought about the outcome for each one. This allowed us to create our project with almost the exact idea of what it should look like in all of our heads.
Some things that could have been done better was our time management. A few times we had to delay our building since we left some of the parts at home. This only happened twice however and didn't set us back that far. We could have also stayed on task more towards the end and practiced our script since I wasn't complete familiar with the note cards we had made. This was however the best project this school year however for me and I had a lot of fun working on it.
