Unit 3 Reflection

This unit was about the cardiovascular and respiratory systems. The cardiovascular system works to pump blood and nutrients throughout our body. The blood's main organs and accessory organs include the heart, the lungs, the kidneys, the small intestine, and the large intestine. The heart is the main organ which pumps blood through the rest of the body through the use of vessels (veins, arteries, and capillaries). Cardiovascular health is avoiding heart attacks, strokes, or other heart diseases. Heart disease and stroke can be caused by high blood pressure, high cholesterol, smoking, unhealthy diet, alcohol consumption, diabetes, obesity, lack of exercise, stress, or genetic history, among other factors. Heart disease and stroke can be prevented by controlling blood pressure, controlling cholesterol, stopping smoking (or not smoking in the first place), eating a healthy diet, moderating alcohol consumption, controlling diabetes, controlling weight, exercising, and managing stress. I would like to learn more about strokes as my grandaunt just experienced one this weekend. I would like to know how to take care of those who go through this experience and I would like to learn of more warning signs for it. I think my strengths were understanding the functions of different parts of the circulatory and respiratory systems. One of my weaknesses was not being able to remember the different veins and arteries which entered and exited the heart. I'm slightly following my Unit 2 health goals as I'm eating better but I'm not following my goals as I'm not sleeping as much as I should. For the remainder of the semester, I wish to do better on tests, and I wish that I get more sleep.
