Description of Project
What we did for this project was research and built models for two system in our body. Those two systems were the respiratory and muscular system. After we researched and blueprinted our model we started the building process. We decided to make the lungs out of a soda bottle and balloons.We showed how the lungs expand when we breath. For the muscular system we created arms which moved up and down due to a hinge. We attached string to the arms to show the muscles contracting when the arms moves. Here are some pictures.
Here is our presentation!!
Content
I am going to give the definitions of all the key terms.
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. This was used in our project because we had to pick a human body system to build.
The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body's airway and has the vital function of providing air flow to and from the lungs for respiration. In our model this was shown by a straw. This was a big part of our model
The pharynx is the body cavity that connects the nasal and oral cavities with the larynx and esophagus. It is commonly referred to as the throat. The pharynxis part of both the digestive and respiratory systems. This part is also shown by a straw at the top of our model.
Larynx: A tube-shaped organ in the neck that contains the vocal cords. The larynx is about 5 cm (2 in.) long. It is part of the respiratory system and is located between the pharynx and the trachea.
Bronchi are the main passageway into the lungs. ... The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
Alveoli are tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream. Learn more about how they function and quiz your knowledge at the end. This is shownby balloons in our model.
The diaphragm is the primary muscle used in the process of inspiration, or inhalation. It is a dome-shaped sheet of muscle that is inserted into the lower ribs. Lying at the base of the thorax (chest), it separates the abdominal cavity from the thoracic cavity.
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named musclesthat make up roughly half of a person's body weight. This was our second part of our model. It is shown by the arms.
The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive. Our "bones" are shown by wood blocks in our model. Probably the biggest point to it.
Smooth muscle: Along with skeletal and cardiac muscle, one of the types of muscle tissue in the body. Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder. This is shown on our model by the rubber bands.
Cardiac muscle (heart muscle) is one of the three major types of muscle, the others being skeletal and smooth muscle. It is an involuntary, striated musclethat is found in the walls of the heart. ... Cardiac muscle contracts in a similar manner to skeletal muscle, albeit with some important differences.
Reflection
This group and project was very very fun. I personally enjoyed all the work that we did. I loved all the research on the human body. My mom was a paramedic so our family is very involved in the human body.In the end I really felt that I had a great skillset in the human body. I learned all about the respiratory system and the muscular system. Two peaks in our lab was our work ethic I feel like we really got things done when they needed to. A key factor of that was that we got the privilege to pick our own groups. I feel like I worked very well with my group, we are all good students so it worked out well. Another positive is that our presentation went very well. We worked hard on our presentation in the maker space . With many hours of preparation for our presentation it came out well.We all spoke well and fluidly. It was also put together very well.
Some negatives that went on in our group was our work ethic. I feel as if because we got the privilege of choosing our own groups, we became too comfortable in the end. We slacked off because we knew we had a great project. That shouldn't be the case because you should always be looking for ways to improve it. Another negative about this project was the blueprinting process. I didn't like it that so much so therefore it was a negative. Im more of a person that likes to wing it and not use blueprints. So I wasn't a big fan of it. Overall this was a great project, I had a great time.
