What was this unit all about? The unit first focused on the heart and it's physical features and how blood flows through the heart. In the second half of the unit, we discussed cardiovascular health in regards to the difference between a stroke and a heart attack, the circulatory system, the functions and dysfunctions in our blood vessels, components of blood, and how the respiratory system allows us to breath. To learn more in detail about the heart, please check out my Mid-Unit Summary. Visit our Heart Chalk Walk, to see our demonstration of the circulation of de-oxygenated blood traveling throughout the heart, into the lungs to become oxygenated, and then carried throughout the rest of the body.

Maintaining cardiovascular health allows our bodies to have apt circulation of blood through our arteries. Proper circulation in and out of our heart prevents from inhibited blood flow which may result in heart disease, such as atherosclerosis or a stroke. When blood flowing to the myocardium in severely slowed or stopped, heart cells may be damaged which could result in a heart attack. They are often caused by atherosclerosis, where excess sugars and polyunsaturated fats cause LDL also known as "bad cholesterol" to stick to damaged cells and turn into plaque. The plaque then clogs the blood vessel and hinder blood flow. A stroke occurs when blood flowing in arteries connected to the brain are interrupted. There are tow types of strokes: ischemic stroke and hemorrhagic stroke. Ischemic strokes are often caused by atherosclerosis and account for 80% of all strokes.
In terms of caring for my own cardiovascular health, I can avoid eating foods high in fats and oils, and inform people about the dangers of atherosclerosis. Being aware of my cardiovascular health at a younger age will greatly contribute to the prevention of heart disease and strokes in the future.
I want to learn more about the various removal methods for the plaque that gets built up during atherosclerosis. How effective is this surgery process and how do patients recover from the removal. I also want to investigate more on my blood type, as my parents have told me I am type O-, but they are not fully certain. Lastly, I want to look into patients who have suffered from stroke and see how they are coping and healing from the damage. Possibly even visit a care center and talk to those who have have suffered as well as the physical, speech and language therapists who are helping them learn to deal with their condition.
Throughout this unit, I found that I learn the best through thinking through the physical process, drawing out the diagrams, and studying through tactile means. The heart chalk activity really helped me understand the blood flow in the heart as we really had to think about each individual artery, vessel, and direction of the blood before drawing and modeling the process. I really enjoyed the heart dissection collaboration/video because it allowed all the members in the group to actively participate and think about each part of the heart in the packet. Since our heart was not clearly obvious which parts were which, talking it out with each other, finding pictures online, in our notebook, and from the diagrams; we were able to take prior knowledge we had and work collaboratively to figure out our sheep heart together.
Reflecting back on my Unit 2 health goals, I have allowed myself to be more aware of the unhealthy junk foods I can easily tend to eat and I'm more able to restrict myself from those temptations now that I know how harmful they can be for my body. I can still work on waking up earlier to cook a hardy breakfast, but I have definitely seen myself being more conscious about my eating decisions and paying more attention to packaging. For the remainder of the semester, I hope to improve my scoring on the exams and have better preparation. As I often miss some of the smaller details in the notes, I plan on creating flashcards for the upcoming unit test and guiding my studying and the information on my cards along with the study guide. I hope that the flashcards will help me understand the terms I am not clear or sure about, resulting in a better performance on exams.
