This unit focuses on the cardiovascular system with topics such as the circulatory system, heart, blood, and respiratory system. The cardiovascular system transports materials throughout the body, removing waster materials and providing cells with needed resources. The circulatory system transports blood through a network of tubes with the heart as the pump. Accessory organs include the lungs, kidneys, and the intestines. The respiratory system is the transportation of oxygen and carbon dioxide through the lungs.
Cardiovascular health is measured by the ability of the body to transport blood throughout the body. Heart attacks is when the blood supply to the myocardium is reduced or stopped and can lead to damaged heart tissue. It is caused by blockages which are usually due to atherosclerosis. Strokes are caused by interruptions to the blood supply in the brain and can cause permanent damage.
To avoid these health problems you should control your blood pressure and cholesterol levels by eating healthy. It is also important to get exercise and manage you stress.
I still want to learn more about how drugs effect the heart and what effects different. substances can have on blood. I also wonder how heart surgery is performed.
Learning Reflection
I learned a lot about different terms and concepts. It was easier to understand important concepts than to memorize terms. I learned to manage the material in class by spreading out studying instead of cramming and to review after I learn new material after a lecture.
I am still trying to meet some of my health goals, but I am definitely getting more sleep and still trying to eat healthier.
