Summary:

     The spinal cord is one of the most important, if not the most important organ. It sends information and instructions to and from the brain and the body. Without it, the entire body and the brain is virtually useless since the brain and body can no longer communicate with each other. If you split or damage a part of the spinal cord, anything below the damaged area will no longer function temporarily or permanently depending on how severe the damage is. Once damaged badly enough, the spinal cord cannot heal itself the right way. The nerves that were damaged do not know where to heal to, so instead of the damaged nerve re-connecting to a nerve that it split off of, it connects to the wrong nerve. Since the spinal cord is the most important organ in the body, it must need more protection and should have the ability to heal itself. 

Backward Looking - Have you done a similar kind of work in the past (earlier in the year or in a previous grade; in school or out of school)?:

     Yes, I have done a similar assignment to this project which I did in 5th grade. In this assignment I was supposed to write in my blog the organs about a particular body system, the function, how to simulate the function of that body system based on activities we did, how to keep it healthy, and 5 interesting facts (or fun facts) about that body system. The body systems that I wrote about were the Nervous, Skeletal, Muscular, Digestive, Urinary, Cardiovascular, and Respiratory System. Doing this assignment gave me prior knowledge to help me with this project by telling me what each body system is composed of and how they work.

Inward Looking - How do you feel about this piece of work? What parts of it do you particularly like? Dislike? Why? What did/do you enjoy about this piece or work?:

     I believe that the Human Body 2.0 Project for me went fairly good. The reason why I think that way is because the I thought that the Written Argument and Design Brief went well since we gave as much information as we could give in detail and the rationale of why we wanted to redesign the spine that way. However I personally can't feel the same way for the presentation. I feel like that the presentation was rushed and unpracticed. It did contain almost all the information for our re-design except for the counter argument and rebuttal, but I still think the presentation could have been better.

Outward Looking - Did you do your work the way other people did theirs? In what ways did you do it differently? In what ways was your work or process similar?:

     When I observed other people's presentations, some were similar and some were different but mostly similar. Similar to my group, many people proposed their re-design of their body system through slide presentations. When I saw other presentations, I noticed that some groups did their presentations in a different way. Some people used animations or videos to show their re-design. One group that was re-designing the digestive system even added skits and a video to their slide to show what the problem with their original design was, their re-design, and the simulation.

Forward Looking - What would you change if you had a chance to do this piece over again?

     If I were to do this piece over again, there are two things that I would change about this project.  The two things that I would change about this project is the idea of how to heal the spine and the overall presentation (since as said before, i'm not necessarily proud of it). To heal the spine, rather than having axons stretch to protect the nerves as said in our presentation, I would have DNA to contain instructions for each nerve cell. When a spine is damaged, DNA should tell the damaged nerve cells what specific nerve to connect to when healing. Regarding our presentation, I would change the presentation to a video since a video is easily changeable compared to a live presentation and I would add the problem with the re-design of our spine and how we are going to fix that. 

Spinal Cord Redesign (11/7 - 11/10)

Summary:

     The spinal cord is the organ in your nervous system that is made up of bundles of nerves. It connects with your brain and the rest of your body. The function of the spinal cord is to send information and instructions from the brain to the rest of your body and give information back to the brain. For example, if you wanted to move your hand, your brain will send a signal that goes through the spinal cord and to the hand telling it to move. If you get injured at a certain body part, say the hand, the hand will send a signal to the brain through the spine to tell the brain that it is injured. The spine is extremely important because it sends instructions and information to and from your brain and your body. Without the spinal cord you wouldn't be able to move or feel anything at all. 

SP6 - Constructing Explanations and Designing Solutions:

     This week I constructed explanations about the spinal cord through my team's design brief. With my team, I explained the original function of the spinal cord, which was to send info and instructions to and from the brain and body. We then explained the issues with the spinal cord such as the durability of it and how it  couldn't heal the right way once broken. We designed a solution to the fact that the spinal cord isn't durable by saying that we could encase the spinal cord into something really durable and flexible such as carbyne. If the spinal cord wrapped in carbyne does manage to break itself  (which is very unlikely), there could be instructions in the DNA to tell the damaged nerves in the spinal cord what to and what not to do.

XCC - Structure and Function:

     In our redesign of the spine, the carbyne that supports the spinal cord in a few ways. As said before, carbyne is a very durable and flexible material to use. If it were to be encasing the spinal cord, the chances of the spinal cord breaking and the host being paralyzed is very unlikely. Also, since carbyne is very flexible, it acts as the original design of the spine and spinal cord. For example, in the original design, if you jump, the spine kind of coils to fit the structure if your body when you jump. Since carbyne is also flexible but stronger, it could do the same thing. So if you wrap carbine around the spine, the spine will have no problem adapting to it since it is now well protected and is now flexible so it could adapt to almost any position that the human gets in.

     

Is it healthier to be a Vegetarian or Omnivore? - WAC

By Joshua Santos, 2026-7B

     It is much healthier to be an Omnivore, or someone that eats both vegetables and meat. Omnivores eat meat which provide healthy vitamins that improve system. Humans were also designed to eat meat and do not have the same stomachs as herbivores and cannot get the most out of vegetables and plants. Also, myths regarding meat eaters to live shorter lives or have cardiovascular diseases were in the past proven false thoroughly and many times. Omnivores are not excluded to eating vegetables and plants, so Omnivores eat both meat and plants which both in total provide vitamins and fats that improve the health and performance of the body and healthy and many minerals such as iron.

     Omnivores eat meat which provide healthy vitamins to improve body systems. According to the article ¨Is It Healthier To Be A Vegetarian Or Omnivore?" by ProCon.org, it states that meat provides vitamin B12, which makes the digestive and nervous system more healthier. This agrees with Kris Gunnars in the article ¨7 reasons not to avoid meat (unless you want to)¨, which says that meat provides protein and according to this article, it says: ¨Another thing protein is important for is bone health.¨ These two articles show that meat is necessary for skeletal, digestive, and nervous system health. Also, an article called ¨Is It Healthier To Be A Vegetarian Or Omnivore?¨ by the Science Education for New Civic Engagement and Responsibilities or SENCER says that ¨And yet, meat products contain creatine and carnosine, which are beneficial to the brain and muscles¨"and shows that meat is also healthy for the brain and muscles.

     Humans were not designed to live off of only vegetables. In the article by Kris Gunnars titled ¨7 reasons you should not avoid meat (unless you want to)¨, it clearly says ¨Our digestive systems are well equipped to make full use of the fats, proteins and nutrients from animal foods¨ and ¨Humans have much shorter digestive systems than herbivores and don´t have specialized organs to digest cellulose, the main fiber in plants.¨ By reading these two quotes, I learned that humans were specifically built to benefit from meat and cannot live off of plants and vegetables because they cannot digest cellulose, so humans cannot get the most out of eating plants. Kris Gunnars also illustrated the idea of meat benefiting humans by saying ¨Humans also have canines, with big brains, opposing thumbs and the ability to make tools to hunt. Meat was one of the reasons humans were able to evolve such large, elaborate brains." This information clearly shows that humans were able to evolve from meat which shows meat's usefulness to humans.

     There are many things that are beneficial to being omnivorous. One of them is the ability to eat both meat and vegetables/fruits. That means that omnivores can benefit from vegetables and meat. ProCon.org states in the article "Should people become vegetarian?" that "A vegetarian diet provides a more healthful source of iron than a meat-based diet." and "Eating meat provides a better source of iron than a vegetarian diet." From these two quotes alone, I learned that  a vegetarian diet provides healthier iron while meat provides more iron. If you eat both vegetables and meat, you get more iron and healthy iron as well, which is good for your body. Meat also provides vitamins that are necessary to make your nervous, muscular, digestive and skeletal system healthier as said in "7 reasons not to avoid meat" by Kris Gunnars and "Is it healthier to be a vegetarian or omnivore?" by SENCER. Also, ProCon.org shows in the article "Should people become vegetarian?" that "A vegetarian diet delivers complete nutrition and can provide health benefits." If you combine the complete nutrition, health benefits and healthy iron with the helpful vitamins, proteins, fats, and nutrients which make many of your systems such as the nervous, muscular, skeletal, and digestive system healthy from meat, you can with no doubt see that being an omnivore is much healthier than being vegetarian.

     There are some things people think are beneficial to being vegetarian. Some of these things are 'if you are vegetarian you live longer' and 'eating meat can cause cardiovascular diseases.' Both of these facts were proven false many times. According to the article "Should people become vegetarian?" by ProCon.org, they show that this fact is indeed false saying "Vegetarians do not live longer. This myth stems from the fact that vegetarians tend to be more health conscious overall..." Kris Gunnars also says in the article "7 reasons not to avoid meat" that meat does not cause cardiovascular disease saying "The main reason for these claims is that meat is high in saturated fat." and "Studies now show that saturated fat in the diet is not linked to heart disease." This shows that meat does not cause cardiovascular disease so you should not worry about this disease when eating meat. This article also claims that there are no health benefits to avoiding meat. "Despite the claims, there is no strong evidence that avoiding meat leads to health benefits. True... there are observational studies showing that vegetarians have a lower risk of several diseases. However, these results are largely explained by the fact that vegetarians are more health conscious overall and are more likely to exercise, less likely to smoke, etc."

     In conclusion, being omnivorous is more beneficial than being vegetarian for various reasons. These reasons include the fact that eating meat provides proteins, nutrients vitamins (especially vitamin B12), fat, etc. that make your body more healthier and stronger. Omnivores also don't only eat meat, they also eat vegetables which means that they can benefit from plants that provide healthy iron, a diet filled with iron, nutrients, and carbohydrates. Being vegetarian isn't healthier than being omnivorous as said by "7 reasons you should not avoid meat" by Kris Gunnars. In fact, being vegetarian is worse than being omnivorous due to the fact that you´re only limited to vegetables, you have to find another source of protein, and you do not have vitamin B12 which makes your bones, digestive system, brain and central nervous system and muscles not as healthy and strong in comparison to an omnivore.
