Osteopetrosis, “the marble bone disease” affects about 1 in 100,000 to 500,000 individuals each year. Osteopetrosis is a rare disorder that causes bones to grow abnormally and become overly dense. When these bones become overly dense, or “marble-like” they become brittle and can fracture easily. During bone remodeling, the old bone is removed or resorbed by the osteoclast cells, and osteoblasts form new bone. However this process does not work for individuals with osteopetrosis. Instead, the old bone is not removed or resorbed, as the new bone is formed.

**There is suppose to be a video included in this post, but WordPress won’t allow me to upload, so here is the material that was included in the video:

My STEAM project was about the Wim Hof Breathing Technique. His breathing technique is said to have many health benefits when practiced with time and commitment. The piece of art I made is an interactive piece. Much like a children’s book. The pull tab at the bottom represents breathing and the little flip tabs up top are for inhaling and exhaling. I took a video of this, but was having trouble uploading it, so email me if you would like to see it in action.

My steam project is on valvular heart disease. I describe the pathway of blood through the heart and circulatory system and diseases of heart valves that affect this blood flow. This picture shows a healthy non-diseased heart next to an enlarged heart with a leaky pulmonary valve.  The link above is how to access a video I recorded to describe both hearts.

The red cake illustrates a normal   functioning heart. The black cake demonstrates a heart that has experienced a heart attack. The color black, shows that blood clots have blocked the blood flow to the heart. The cut piece illustrates loss of tissue and damage.

I made my project into a video like I did last semester, because I thought it was a unique and simplistic visual aid that everyone can watch and receive the message almost instantly. I hope that this style is okay with everyone; as making movies is actually a passion of mine and I am not very good at hands on crafts and art projects. My project is on the changes that occur during pregnancy, specifically to the breasts of a female’s body as it undergoes the changes necessary to facilitate the growth of life. I made a time-lapse video of myself sketching the breasts before pregnancy and breasts during pregnancy. Many changes take place during pregnancy, and a lot of changes actually take place in the breasts themselves. In my exterior sketch, you can see that the breasts become fuller and this is because the female body begins the production of milk when they start growing a child inside of their uterus. You can also see that purple stretchmarks appear as the breasts grow bigger, and these are due to the stretching of skin as they expand. Another important exterior change Is that the areolas and nipples increase in size and sometimes become darker due to increased blood flow to the breasts. These exterior changes are the ones that we hear about the most because they are the changes that we can actually see when we examine them, but there are also many important changes occurring on the inside as well. An increase in estrogen levels allows extra growth of milk ducts and glandular buds that help to produce the milk that the mother will eventually feed her baby with. Other hormones that play significant roles in milk production are human placental lactogen, luteinizing hormone, and oxytocin. As the breasts swell making room for milk storage, the milk ducts extend and elongate in order to accommodate this change. I really enjoyed learning about all of the changes that occur during pregnancy, as someone that would like to be a mom one day, I was interested in how my body will change throughout my pregnancy. I think that pregnancy is such an interesting topic and the reproductive system was one of my very favorite units from this entire class. I think it is very important to recognize all of the changes that a woman’s body goes through in order to bring life into the world, and I think it makes the whole birth process even more incredible and miraculous. Our bodies work hard to keep us alive and well throughout our entire lives, and when a woman becomes pregnant her body not only takes care of itself, but takes care of another life as well and that is something that I find absolutely amazing. The human body is incredible and I just wanted to say how grateful I am to have been a part of such a great class full of great people these last two semesters! Learning about the human body has been an amazing experience that I will not soon forget! Thanks for a great semester, you guys and have a wonderful summer!

All my best,

I talk about the humoral adaptive response and have an interactive activity to show you how the symptoms of RA affect the patient.

My STEAM project is about juvenile polyps. I made a short video explaining how juvenile polyps disrupt our digestive system, a unit we most recently went over. I also share how polyps develop under an unfortunate mutation in the immune system. The immune system is a unit we went over towards the beginning of the semester.
