We choose CrossFit as our topic for the Monday Wellness presentation because we both really enjoyed the CrossFit workouts in our P.E. class. While preparing for the project, I was surprised at how many workouts there really are and the health benefits of CrossFit. The topic is important for health and wellness because CrossFit helps to improve on an athlete's intensity, motivation, efficiency, and heart health. In addition, CrossFit helps build relationships and increases joint mobility.
I would probably grade myself a 6 out of 10 because as a group we were really uncoordinated and our activity was poorly planned. We should have a more group dynamic activity in which we would go through at least 2 other workouts and have a more defined tutorial.
I was actually surprised at how CrossFit is incorporated into athletes' workouts and even the US military workout. If I do need to exercise in a short amount of time at high intensity, I would use CrossFit because CrossFit has many more benefits than I thought it would have.

Sheep Heart Dissection
1. The purpose of the pericardium fixes the heart to the mediastinum, gives protection against infection, and provides the lubrication for the heart.
2. Veins have thinner walls than arteries and are one way valves. Arteries, on the other hand, are elastic, meaning that they expand when the heart contracts and recoils when the heart relaxes. In addition, arteries are contractile, meaning that the smooth muscle tissues cause vasodilation or vasoconstriction.
3. The function of the auricle resembles an ear that is part of the heart and serves as extra volume for the heart.
4. The walls of the ventricles are thicker than those of the atria. The atria are the upper chambers of the heart and the ventricles are the lower chambers of the heart.
6.
7. The ¨anchoring¨ of the heart valves by the chordae tendineae and the papillary muscle is important to heart function because
8. The chordae tendineae connects the papillary muscles to the tricuspid valve, which is shown in question 6.
9. The function of the semi-lunar valves is to prevent backflow of blood from the arteries to the ventricles during ventricular diastole, and to help maintain pressure on the major arteries.
10a. The valve disease´s occuring on the right side of the heart might result in the swelling of the feet and ankles because blood on the right side of the heart comes from the inferior vena cava, the lower part of the body.
10b. If the valve disease occurs on the left side of the heart, the brain and the upper part of the body might be affected by this disease because blood on the left side of the body comes from the superior vena cava, the upper part of the body.
11.
12. The left and right sides of the heart differ from each other because there are four hollow chambers in the heart. There are two chambers on the left side- the left atria and the left ventricle- and two chambers on the right side- the right atria and the right ventricle. The right atria is upper chamber, receiving oxygen deprived blood. The right ventricle, a lower chamber, discharges blood. The left atria, the upper chamber, receives oxygen rich blood. The left ventricle, the lower chamber, is the thickest wall.

Unit 3 Reflection
- Cardiovascular health is the factors needed to maintain a healthy heart. It includes exercising, maintaining a healthy weight & diet, controlling blood pressure & cholesterol, preventing atherosclerosis, not smoking, minimizing stress, controlling stress, and laughing.
- Heart disease is caused when the blood supply to the myocardium severely reduced or stopped, resulting in damage to heart cells or death of heart cells. Due to heart disease, one or more coronary arteries is blocked usually from atherosclerosis and detrimental effects ensue. Such effects include myocardial ischemia, fibrillation, cardiac arrest, and the death of the myocardium.
- Stroke occurs when the blood supply to the heart is interrupted. Stroke is often referred to as the "brain attack" or the CVA (cerebrovascular accident).
- The cardiovascular system delivers nutrients and oxygen to all systems in the body. The arteries carry blood away from the heart; the veins carry blood to the heart. Blood enters the right atrium from the inferior and superior vena cava. It passes through the tricuspid valve and enters the right ventricle. Then, it passes through the semilunar valve to the pulmonary trunk to the pulmonary arteries and out to the lungs. the lungs exchange carbon dioxide for oxygen. After entering the lungs, the pulmonary veins return the blood to the heart through the left atrium. It passes through the biscuspid valve and enters the left ventricle. Then, it passes through the aortic semilunar valve into the aorta and out to the body.
After this unit, I wonder about the life stories of those who had the cardiovascular diseases- their struggles and their recovery from the diseases. Those real life stories would help me better understand the impact these diseases have on people's lives.
My strengths are understanding the cardiovascular diseases, but I still have trouble on understanding the cardiovascular system.
I believe that I am handling my Unit 2 goals quite well. I have an overall healthy diet and exercise vigorously for at least three times a week. My goals for the rest of the semester are to continue achieving these goals.

Healthy Snacking
The apple and almond nut butter combination which I created was enrich in nutrients, such as protein and various of vitamins.
1. I snack often during the tennis season, which occurs mostly during the fall. However, in other times during the year, I do not typically snack on foods.
2. Typically, a healthy snack is enriched in nutrients and less than 200 calories.
3. Snacks you should stay away from are foods that are pigmented and have a lot of artificial flavoring.
I liked that this activity focused on the benefits of eating and provided a healthy snack at the end of the lecture. Their presentation was very sharp and created a unique snack that I have never had before.

Blood Pressure Lab
1. Test 1 of my blood pressure was 105/60- the systolic pressure being 105 and the diastolic pressure being 60. Test 2 of my blood pressure was 100/60- the systolic pressure being 100 and the diastolic pressure being 60.
2. To measure the heart rate, a stethoscope is used.
To measure the blood, a sphygmomanometer is used.
3. You should not use your thumb to measure your pulse because you might be accidently measuring your thumb's pulse.
4. A sphygmomanometer is an instrument that measures blood pressure, consisting of an inflatable cuff applied to the arm to measure the systolic and diastolic blood pressure.

Unit 2 Reflection
Health is the measure of our body's efficiency and over-all well-being.
Typically, I eat substance from each food category, but I feel that I should focus on eating more fruits & vegetables. At SHS, however, there are many instances in which I see students eating Cup O Noddles and drinking pearl milk tea. There are others who eat salads and fruits during lunch, but the majority of students eat unhealthy foods. The tendency, for the most part, is that students eat only what tastes "good," instead of what the body needs to perform well. At school, the cafeteria should offer more fruits and vegetables rather than cheaper, affordable foods, such as Cup O Noodles and cookies.
From this unit, the essential topics for this unit were health, nutrition, exercise, sleep, and stress. I learned that there were three stages of stress- the alarm phase, the resistance phase, and the exhaustion phase. Although I knew there were different levels of stress, I never knew there was a precise stage for each level of stress.
I still do not understand how the hormones- insulin, leptin, glucagon, and cortisol- play a role in keeping the body healthy. For the next unit, I want to understand difficult topics in class rather than attempting to learn the information the day right before the test.
The foods which students eat in class, Cup O Noodles, reflect the health problems that may arise in the future. Cup O Noodles has high levels of sodium and barely any nutritional value, which increases the blood pressure and can cause cardiovascular disease. Therefore, if there is a possibility not to have salt on your food, do not add salt and add another substitute of salt.
