Sheep Heart Vivisection

Q.1 The pericardium's purpose is to protect and anchor the heart where it is.
Q.2 Arteries have thicker walls than veins do. Veins have valves to prevent back-flow of blood.
Q.3 The function of the auricle is to expand the blood capacity of the atrium.
Q.4 The vacuum sealing of our heart collapsed the atria, but we could still see that the atria are larger than the ventricle.
Q.6 Anchoring of the heart is important because it keeps the heart in place so it isn't damaged during movement.
Q.8 The function of the semilunar valves is to prevent backflow from the ventricles to the aorta and pulmonary trunk.
Q.9 With valve disease on the right side of the heart, the swelling of feet and ankles is due to blood pooling in the feet because there is nothing to prevent back-flow so gravity will push the blood. If valve disease occurs on the left side of the heart, the complications would be a decrease in blood flow and a lack of oxygen reaching the body.

Q.11 The right side of the heart is significantly smaller than the left side because the left side needs more muscle to pump the blood through the body.

Monday Wellness Reflection

This past Monday, Cole and I had done our Monday Wellness presentation on the benefits and process of weightlifting. This is a very important topic for me because as an athlete and someone interested in going into an athletic profession in the future, I do a fair amount of lifting throughout the year. Since Cole also lifts for baseball, we thought this topic would be something we would be able to teach pretty easily. We could tell that only a few people in class actually did lift, so we thought it would be pretty eye opening for people to see the benefits and science behind lifting. Although that may have been wishful thinking considering the physical activity that early on a Monday was not very appreciated by my fellow classmates.

I learned a lot researching this topic. Going in I only knew what the benefits of weightlifting were and how it affected the body. I didn’t know the science behind how the muscles grow and why they do it. Hypertrophy was the most interesting thing I learned about because it answered most of my questions concerning how muscles grow. I knew that when the muscle got stronger, it got bigger, but I didn’t realize that it was the growth of the fibers not just more fibers being created.

Our topic is very important for health and wellness because it is one of the main ways that people stay in shape. Exercise is one of the pillars of health we learned about in the previous unit. Because weightlifting is so strenuous, it causes the body to work hard, which means it’s using calories and fat stores, ultimately leading to an increase in muscle and a decrease in fat. Lifting can help increase self esteem and relieve stress. It also reduces the risk of colon cancer just like everything else we have learned about this semester.

I would give myself an 8 on this project. I felt that I stuttered a lot during my parts of the presentation and that my activity was not very effective in teaching my classmates about weightlifting. I also think that our project didn’t go into the science of weightlifting as much as it could have. I do however believe that my memes were on point and should receive props for an entertaining powerpoint. I feel that they were essential in keeping the other students engaged and active during the presentation. I think that everyone had an enjoyable experience during our presentation and even though it may not have had a lot of new information, it at least wasn’t very repetative.

I feel like our topic was too general and that made it hard to figure out what to make specific in our presentation. We should’ve chosen a particular lift or gone into more depth about crossfit something like that, but what’s done is done.

On another note, how do people even get colon cancer when going everyday activities helps prevent it?
