I decided to do my project on osteoporosis because it was very interesting to me, and a few of my family members have osteoporosis so I wanted to learn a little more about it. My drawing shows what happens inside of a healthy bone, and what happens inside of a bone with osteoporosis.
My STEAM project is about the five major classes of Antibodies or immunoglobulins called IgM, IgA, IgD, IgG, and IgE. Though they are found throughout the body’s secretions they produced by effector B cells and are secreted by Plasma cells. Though some Antibodies vary in size and structure they each have the minimum characteristics of antibody monomers (four protein chains bound by disulfide chains), the lightest of which forms the antigen binding site. The heavy monomers (high molecular weight) contain variable and constant regions, the constant region means that the amino acids are the same throughout the classes of Antibodies, the variable region is unique for every Antibody. Antigens bind at the ends of each Antibody structure at the variable regions where it forms a y-shape. The other end of the Antibody binds to B-cells, phagocytes, mast cells, or simply float free in the plasma depending on which Antibody it is.I couldn’t figure out how to post multiple pictures so please go to the link to view the paintings. –Antibodies in Waterco
My visual aid is a cartoon stating the various componets of blood and the function of blood in the human body.
(Apologies that it’s difficult to see, this is as good of quality of a picture as I’m currently able to upload)
Blood is compromised of four main components; red blood cells, white blood cells, plasma, and platelets.
Plasma is the fluid in which red blood cells, white blood cells, and platelets are held and plasma is what allows these components to circulate throughout the body.
Primarily, red blood cells are responsible for carrying oxygen to tissue from the lungs.
White blood cells are commonly referred to as leukocytes which are responsible for the bodies immune system. Leukocytes is the group name of wide variety of immune system related cells.
Plateletes are resposible for blood clotting to expedite the healing of wounds and prevent excessive bleeding.
This is my STEAM project
I’ve assembled thin tubing, as if it were the filtration of air within some contraption, to represent the lymphatic system moving lymph through its tiny lymph vessels. I’ve added a T divider to help represent a filter or a lymph node. From one end of the T divider, the pathway continues to cycle within the mainline, like in the lymphatic system, but the other end is the pathway to the dust collector, which would be emptied when full. I used fish food to represent the “dust” which in turn represents whats left of bacteria when the white blood cells are done with them. Just as within the lymphatic system lymph nodes filter the lymph then what’s remaining ends up going to the urinary bladder which is later excreted from the body. Thus ending the filtration of the air in my representation as well as lymph in the human body.
For my project, I made a model of a chest with the rare heart condition, Ectopia Cordis. It was my goal to simulate the effects of this condition as it would appear on a newborn, and depict how the heart develops outside of the chest cavity, and is made visible from the abdominal wall. I based my topic on Course Objective #42, as I wanted to learn more about abnormalities in the formation and structure of the heart. I believe I also briefly touched on Objective #19 as well, as this defect is formed during the early development of a fetus. This condition is cause when the sternum doesn’t fuse properly in utero and as the heart forms, it does so from the protection of the chest cavity. Despite the high mortality rate at infancy, several patients with this condition are able to still maintain a lifestyle, but are at risk of higher health complications. To simulate the condition, I baked a loaf of bread to act as the chest area and inserted a potato in the center to act as the heart. I used red dye and spray glue to give my “heart” a more realistic, textured appearance at it emerges through the “cavity”.
My STEAM project this semester includes an abstract collage piece on Wilson’s Disease, a disorder that causes an accumulation and build up of copper in the body and several bodily organs. Thank you!
Osmosis is the diffusion of water. This pendulum represents the passing of a water molecule through a membrane at osmotic equilibrium. Osmosis continues to happen as the molecule of water passes back and forth through the membrane represented by the cone on the back of the pendulum. The membrane also contains aquaporins, which is the part of the membrane responsible for the passage of water. Without the presence of aquaporins water could not pass through the membrane in both directions which means osmosis would not be possible. The stones on the base represent concentrations. The darker the stones the more concentrated with water it is. Since osmosis works down the gradient from high to low concentrations the pendulum representing the water molecule, swings back and forth between the the two areas of concentration traveling from an area of high concentration to an area of low concentration. This will happen continuously at osmotic equilibrium.
