Heart Dissection Lab Questions
1. The function of the pericardium is to secrete a fluid that lubricates the heart in order to reduce friction.
2. The arteries have thicker and stronger walls because they need to deliver blood to the whole body while veins have thinner walls.
3. The auricle's function is to increase the capacity of the atrium, so it can contain a higher volume of blood.
4. The muscles around the ventricles are thicker than the muscles around the atria. The atria also seem smaller than the ventricles.
6. When you cut into cross sections, the bicuspid valve is able to be seen
7. The anchoring of the heart vales by the chordate tendinae and the papillary muscles are important to the heart function because they allow the valves to prevent the back flow of blood by pulling and contracting.
8. We see the inside of the left atrium and then the bicuspid valve, which is held to the walls by the chordinea tendinae and the papillary muscles.
9. The semi lunar valves prevent arterial blood from re-entering the heart, keeping the blood flowing in one direction.
10. a. There would be swelling in the feet and ankles if there is valve disease on the right side because there would be back flow of blood from the heart back into the body and would be carried to the feet and ankles because the right side is where blood enters the heart.
b. If the valve disease was on the left side then there would be complications with the delivery of oxygenated blood to the body.
11. We found an opening in the left ventricle and could see the biscuspid valve.
12. The left side of the heart has more muscle than the right side because the left ventricle needs more power to pump blood to the rest of the body. The right side is smaller because right ventricle only needs to pump blood to the lungs.

Unit 3 Reflection
Content Reflection
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.

Monday Wellness Snacks
The snack contained apple, peanut butter, and almonds. The snack was healthy because it contained protein, anti oxidants, vitamins, unsaturated fatty acids, and fiber.
1. Snacks should be eaten 2-3 hours before a meal.
2. Healthy snacks contain protein and fiber. They also contain carbohydrates and different types of vitamins.
3. Snacks that have empty calories and have artificial flavors should be avoided as well as snacks with saturated fats.

Measuring Blood Pressure Lab Analysis
1. The systolic blood pressure is the first time you hear the blood pumping in the arm when the heart contracts ,and the diastolic blood pressure is the last time you hear the blood pumping in the artery when the heart relaxes.
2. A stethoscope is needed to measure the heart rate and the sphygmomanometer is used to measure the blood pressure.
3. It is not ideal to use the thumb to measure pulse because it has its own pulse and may confuse the counting.
4. First place the cuff on the upper arm of the dominate arm ,and then inflate the cuff, so it fits tightly on the arm. The pump should be held in the other hand so the valve can be easily accessed. A stethoscope is needed to hear the pulse. The cuff should be inflated until the pressure gauge reaches 150 ,and then the valve should be opened releasing air slowly. The first time your heart pulse is the systolic blood pressure and the last time you hear it is the diastolic blood pressure.

Unit 2 Reflection
Health is the measure of our body's efficiency and over-all well being. This definition includes physical,social, and mental health. This is an important topic because students at SHS often ignore their health and put either their activities or school work first. Not getting the proper nutrients, being stressed out, and being sleep deprived can have a detrimental effect on their overall health. Students should recognize their patterns and make a change to live a healthier lifestyle.
In this unit we learned about the five pillars of health: nutrition, exercise, sleep, stress, and social. These pillars are the key to living a balanced and healthy lifestyle. I learned about how to vary my diet and eat from all the food groups as well as the different benefits that come with different types of foods. It was surprising to find out how unhealthy some of the foods I usually have are and in the future I will be paying more attention to what I eat. I learned a lot about sleep, and how important it is to be fully alert and functioning during the day. Exercise is also important for strengthening the body ,and variety is also an important aspect of exercise that keeps us healthy. I also learned about different aspects of stress. Sometimes stress can be good, but prolonged stress can damage your body and can weaken and age your body.
This unit helped me reflect on my own lifestyle and helped me find ways to improve. I plan on eating better by balancing out the food groups I eat from, getting more sleep by planning ahead, and exercising more consistently. By learning about how I can live healthier, I hope I can keep my goals in the years to come and long and happy life.

Nutrition Analysis
After monitoring my diet, I found out that I need to eat a lot more vegetables, fruits, protein, dairy, and protein, but I am meeting my grain requirements. I also need to exercise more because I am currently not in a sport. Based on the stations in the Falcon Market, I could use more seasonal produce in my diet and when eating foods, I should prioritize protein, produce, and healthy fats. Right now I am not eating enough food because I am not meeting some of my requirements for the food groups, so to fix this I need to start eating more balanced meals because for vegetables I am under. I also need more variety.
I should eat more during breakfast and lunch, instead of eating a lot during dinner to make my diet more balanced. I could eat eggs, bread, and fruits at breakfast ,and at dinner I can drink milk. These foods will help me balance some of the food groups out. I could eat more whole grain and seafood for protein to add variety in my diet. These foods will add to the specific categories I am lacking in.
To eat healthy, a person needs to have variety in their diet. They should eat from all the food groups at each meal, making sure they have healthy portions. They should eat seasonal fruits and vegetables because they contain more nutrients.They also need to make sure they get enough exercise. They should avoid unhealthy snacks that contain too much fat and fast foods that are filled with excess sodium and fat because these foods will make you body unbalanced.
