Artifacts+Part+4b









**The artifacts above ( and those on the previous page, 4a,) show the diversity of the Online Anatomy/Physiology Class and this is why I chose them.Student A did well in her hands on work, as these examples show. Both of these wrtting examples are fine and were produced around the first of March and the first of April. //These artifacts are important because they show both hands on and written work and therefore can help us understand more about how Student A learns best. They are valuable because they reinforce the fact that Student A does consistently well with hands on activities, while showing significant variation in her written work. // **

** The artifacts below are a pulled from discussion posts, class blogs, personal anatomy journals and 20 point writing assignments, private thread questions to the mentor teacher and assignment questions. All are examples of my case study student, Student A’s work. Some of the entries have comments by Miss B or myself. They are in reverse order with her most recent work appearing first. I choose to present these examples because they represent a range in time, activities and quality that are not related to time in the class. 

//They are important because in an online class written words must substitute for visual and auditory clues in understanding the student. They are also one of the only ways to check for understanding. I think these discussions are valuable because they give us a clue to who Student A is both personally and academically.// In these discussions and examples of writen work I was looking for inconsistency. As with her other work, and as stated before, Student A's work is very different at times. Sometimes well written with an understanding of the topic and sometimes with a much less mature form of writing and almost a confusion with the conten t.** Student A’s ” voice” is in green in all entries. __My voice is underlined__ Miss B. no underline

__This is a strange entry. Not labeled and didn’t fit any assignment??__ Created on Tuesday, 03/23/2010 10:45 AM by STUDENT A Circulation has a lot to do with the respiratory system, cellular respiration, and muscle contraction. Cellular respiration needs oxygen and carbon dioxide being exchanged through the cells. This happens through circulation. The circulatory system sends blood cells full of oxygen to new cells, and then takes the carbon dioxide out of the cell and transports it back to the lungs. Muscle contraction uses circulation to get oxygen needed to keep the muscles functioning, and the respiratory system uses oxygen, which is moved to different parts of the body through the circulatory system. Student A, what assignment does this belong with? Miss Babson

__A written activity to teach circulation pathways. A few problems (see my comment)__ Week 8 Anatomy Journal Week 8 Anatomy Journal (permalink) Directions to the kidneys (permalink) -edithistorydelete Created on Tuesday, 03/16/2010 8:29 AM STUDENT A DIRECTIONS TO THE KIDNEYS 1. Blood without oxygen is moved into the right atrium. 2. It goes through the tricuspid valve and into the right ventricle. 3. The ventricle pumps the blood through the pulmonic valve. 4. The blood moves through the pulmonary artery to the lungs, where they become oxygen rich. 5. The oxygen rich blood then goes from the lungs into the pulmonary veins, and is transported to the left atrium. 6. Blood then goes through the mitral valve into the aorta. 7. From the aorta, blood is transported all through the body. 8. The aorta transports blood to the renal arteries, which transport blood into the kidneys from the left and right. 9. The renal arteries branch off into segmental arteries, and interlobular arteries, which go into the kidneys. 10. Blood drains from the kidneys into the renal veins, and go back through towards the heart through the vena cava. Comments (1)__Hi A., Looks like you got your RBC to the Kidneys and back. I have two corrections. The valve from the right ventricle into the pulmonary artery is called the pulmonary valve. Blood travels back to the heart by way of the Inferior vena cava. Don’t worry it gets easier. You might want to refer back to your web resources.

The Circulatory and Lymphatic Systems (permalink) -edithistorydelete Created on Tuesday, 03/16/2010 8:16 AM by STUDENT A RE: Bacteria Make Artificial Blood Vessels of the Future Author: STUDENT A Posted date: Thursday, March 18, 2010 8:30:54 AM EDT Last modified date: Thursday, March 18, 2010 8:30:54 AM EDT This article talks about how the cellulose produced by a bacterium, called Acetobacter xylinum, could be used to make artificial blood vessels. It is also found that using material provides for a lower risk of blood clots than using synthetic materials that are currently used. The article said that in real blood vessels, there is an internal coating of cells that make sure that the blood does not clot. The bacterial cellulose has been modified by biologists so that these cells work better. I chose this article because I thought that it was really interesting that there could be an artificial way to make blood vessels using a bacterium. I think this new discovery will help a lot of people in our society. It relates to what we are learning this week because we are learning about the circulatory system and this article talks about blood vessels which are a big part of this system.

__A 20-point writing assignment. I think that this is OK but not complete enough for an honors class. I tended to grade a little harder than Miss B__ The Circulatory and Lymphatic Systems The general function of the circulatory system is to transport materials within the body, and to be the cooling system for the body. This system transports proteins, nutrients, gases, hormones and etc. The parts that make up the circulatory system are the heart, arteries, capillaries, veins, and vessels. The heart is one of the most vital organs. It contracts, pumping blood through the arteries and veins, to be transported by the vessels and capillaries to all parts of the body. When blood begins circulation, it leaves the heart and enters the aorta. From here, oxygen rich blood cells are transported throughout the body.

The general function of the lymphatic system is to transport a watery substance called lymph. In this fluid, there are necessities such as immune cells, that are transported through the body. It also drains fluid from cells and tissues. This system contains lymphocytes, which are immune cells that protect the body. This system is also made up of organs (bone marrow, lymph nodes, spleen, and thymus), ducts, and nodes.

The circulatory system and the lymphatic system interact directly within the body. The lymph collects and transports interstitial fluid such as plasma protein, to the blood. It also absorbs lipids from the intestine and transports them to the blood. Lymph also drains fluid from cells and tissues in the circulatory system.

Fun Facts: Lymph nodes are bean shaped. There is a disease called lymphoma, where the lymph nodes live too long. The aorta is the largest artery in the body. Comments (1) A little more detail, like the chambers and valves of the heart, and the types of blood vessels, would change these from good to very good notes.

__This was the discussion thread for the first week and was done in a blog. The purpose was to create community. Why is community essential to learning?__ Community is a key factor in learning. Cooperation, also, plays a huge role in the advancements of everyone’s knowledge. Everyone has different personalities, which are often conflicting, which is why people tend not to get along. However, if we are able to look past each other’s differences, we can establish a better working atmosphere for everyone. By cooperating and getting to know each other better, we are able to become more comfortable with each other. By being comfortable around each other, we can all feel freer to express ourselves, and not have to fear being judged. By establishing a community with each other, everyone will have a much more enjoyable and beneficial learning experien ce. How is an online community different then a face-to-face community? With a face-to-face environment, you get to see people. You get to observe their expressions, their body language, and their tone. With an online community, we lack senses that are provided in the face-to-face community. We cannot see each other, and it makes it more difficult for us to understand each other. However, by being smart about our conversations, and by putting in some effort, we can establish a relationship online. How can you contribute to our community? All of taking this online course can help contribute to the effectiveness of it. By being open, honest, and inquisitive with each other, we can all help to learn more by asking questions and providing answers. With a better understanding of each other, we can better understand this course and make it enjoyable for everyone.

__Journal Review discussion thread__ http://www.news-medical.net/news/20100208/Beer-may-help-prevent-osteoporosis.aspx STUDENT A I chose this article because the title grabbed my attention. It is always being advertised not to drink alcohol because it may have harmful effects on the human body, but now it is being advertised to help fight off diseases? I would like to see further studies conducted to find out how far this advancement will be taken and what will be the results. Can beer really fight off osteoporosis or just certain levels of the disease? I found it very interesting that a substance that some people think is 'bad' or 'harmful' can really help the world in a positive way. We just need to be more open minded when it comes to the medical field

__These are questions posted to the assignment help and private threads. **Checking and rechecking is typical of Student A.**__

F or the week one timeline, where are we supposed to post the 'fun fact'? Right now, I just posted it in the correct time period, at the end for that time period, but I am not sure if that's where you want it, so I just wanted confirmation on where to put it. Thanks!

I just want to make sure I am posting things in the right area, because I believe you wanted the entry about ten questions about us and the locations of organs in the Anatomy Journals area, but it is due tomorrow, and I am the only one who has posted anything there.

I did the 'which organelle are you?' assignment before the list was up, and I noticed you told someone that they could just pick any one because there was no list. So I did the cytoskeleton, but this morning I noticed it wasn't on the list. Is it okay to leave the cytoskeleton? Or do I have to choose another one and do it all over?
