Respiratory System: The system in the body responsible for the intake of oxygen and the exhaling of waste gases. Lungs: The part of the body where the alveoli are located. Trachea: Also known as your windpipe Bronchi: Tubes that lead to the lungs Diaphragm: The part of the body the controls breathing These are represented in the first section of our model. The oxygen is taken in through the ramp and the waste gases are taken out by the magnets and the dowel. Alveoli: tiny air sacks only one cell think that diffuse oxygen and waste gases with the capillaries Diffusion: The process of material moving from areas of higher to lower concentration of the material. Difussion is shown when our stronger magnets which are the area of lower concentration pull the oxygen from the weaker magnet with a higher concentration. |
Circulatory System: The system in the body used for moving things around the body like oxygen, platelets, and white blood cells. Red Blood Cells: Responsible for carrying oxygen using their hemoglobin. They are shaped like a thumbprint cookie. Iron located in the cell gives them the distinctive red color. White Blood Cells: Protect the body from disease. There are significantly fewer of them than Red blood cells. Plasma: carries salt and enzymes Platelets: form blood clots Capillaries: the smallest blood vessel. The location of diffusion. Veins: Blood vessels that carry blood from the cells back to the heart. Arteries: Blood vessels that carry blood from the heart to the cells. Hemoglobin: a molecule containing iron that bonds with oxygen and carries it to the cells. Located in red blood cells The blood stream is the conveyor belt in our model. The red blood cells are the magnets. |
