Week 13- PP

Submitted by aswan on Mon, 12/10/2018 - 15:04

As blood enters the right side of the heart it enters the right atrium where blood is able to flow without any additional help through the atrioventricular valve and into the ventricle. Eventually the atrium contracts (becomes systole however this term is usually only applied to the ventricle) forcing the rest of the blood still present in the atria into the ventricle. Once blood has built up in the right ventricle it contracts, becoming systole while the atrioventricular valve (AV valve) closes as pressure is now greater in the ventricle than in the right atria. Once enough pressure has built up in the ventricle the semilunar, pulmonary valve opens, allowing blood to flow out of the ventricle and into arties that in the case of the right hear carry the blood to the pulmonary circuit where blood that lacks oxygenation is oxygenated. The left side of the heart follows a very similar process however it’s semilunar valve is called the aortic valve and blood is sent to the systemic circuit where organs use oxygen and nutrients from the oxygenated blood.

New England is home to a very specific type of storm called a nor’easter. This is a storm that develops along the east coast of the United States and reach their maximum intensity around New England and the southern parts of Canada, just north of New England. The polar jet stream transports cold arctic air south across the plains of Canada and through the U.S. then this cold air travels eat toward the Atlantic ocean. The Atlantic waters are typically mild and warm during the winter months because of the jet stream. The difference in temperature between the cold air over land and the warm air over water fuels the energy needed to produce a nor’easter (weather.gov). They usually develop in the latitudes between Georgia and New Jersey within 100 miles east or west of the Atlantic coast.  Nor’easters can occur at any point throughout the year but are most frequent and most violent from September through April (weather.gov).

Nor’easters travel north along the east coast and tend bring a lot of precipitation, usually in the form of snow due to the season in which they are most common.

Stem cells could be the key to treat Autism and find more ways to maybe prevent children to have severe symptoms. Autism is not considered a disease but a condition that affects 1% of the world population. According to the World Health Organization (WHO) that defines the Autistic spectrum disorders as a “group of conditions that is characterized by some degree of alteration of social behavior, communication and language. “

    The METHODS project intrigued me because I haven’t done anything similar to a project like this in college. I knew this project would be a good challenge for me to write methods in a concise and effective manner. I used to think that my writing was very wordy so going into this project I knew I needed to write many drafts for these methods until I found a description that explained my process of finding a spider web in the best way. Throughout my process of writing my methods, I found that my writing ended up clearer than I thought. This showed when my peer student replicated my methods and the replicate was very close to the original. As for the actual report, I was confused as to how to write my findings in an efficient way. It was interesting to determine the distinction between observations and inferences. The practice in writing about these observations was helpful in expressing the findings about the replicate photo without being repetitive or confusing. This project was also helpful in showing how paragraphs should be split up. I never realized how big of an affect splitting up paragraphs has on the flow of scientific paper. I learned that it is important to keep alike topics in one paragraph, rather than scattering it throughout multiple paragraphs.

In the future I would still like to improve my time management skills because I still struggle with leaving assignments and studying until last minute. I was better with this class specifically this semester, however I did find myself slacking in other courses. Not procrastinating would be a very beneficial skill to improve upon because I would find myself stressing a lot less before big assignments or in weeks that have multiple exams and due dates. I could also still better my studying techniques because test taking is still something I struggle with but I did learn a lot about what studying techniques work well for me this semester.

There are many imrovements that I could have made this semester but in going froward, I know alot more about myself as a student and know whar skills I need to improve and work on.
