Chapter 19 The Cardiovascular System: The Heart 1. How is the heart positioned in the mediastinum? It rests on the diaphragm‚ near the midline of the thoracic cavity‚ with about two-thirds of the mass lying to the left of the body’s midline. 2. Which layer of the pericardium is both a part of the pericardium and a part of the heart wall? Serous pericardium 3. What is the function of pericardial fluid? Reduces friction between the membranes as the heart moves 4. From most superficial

metabolism the first thing you might think of is the number of calories your cells burn each day. Metabolism is actually the sum of all chemical reactions that take place in the body. Metabolic reactions that produce energy are dependent on the cardiovascular system‚ which send oxygen to all the cells in your body. Although metabolism is not primarily made of reactions that burn nutrients like carbohydrates‚ fats and protein‚ these are perhaps the most widely known of the metabolic reactions. (CITE)

* GROUP 2: Elrey Joseph Calitis Mae Anjneth Cuaton How Atrial Tachycardia happens? Electrical signals in the heart’s upper chambers fire abnormally‚ which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart’s natural pacemaker. A series of early beats in the atria speeds up the heart rate. The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood flow to the rest of the body is compromised. Video Presentation

Cardiovascular Workout Log You will need to document six hours (or 360 minutes) to include a variety of physical activity. A variety of physical activity can be defined as a minimum of three different activities. Students are expected to log activities multiple times per week for each week enrolled in the HOPE course. You cannot complete and receive credit for this HOPE course if you do not complete each of the topic workout logs. You may either copy and paste this document into a word processing

Statics and Dynamics 1. The diagram below shows the loading on one of the horizontal floor beams and associated supporting vertical columns for a proposed building‚ sited on an incline. In order to consider the worst case‚ assume that the beam is simply supported and the column is pin jointed at either end. 1.1 Determine the beam reaction forces at each support and . Taking moments around (2 x 50) + (6 x 70) + (10 x 20) = (8 x ∴ = = 90 KN So‚ = 50 + 70 + 20 = + 90

Article #1 A study conducted by Capewell‚ Ford‚ Croft‚ Critchley‚ Greenlund‚ and Labarthe (2010) studied coronary heart disease risk factors trends and mortality in the United States. The purpose of this study was to look at cardiovascular risk factors in the United States since coronary heart disease is among the leading causes of death in the world. It is not only the leading cause of death‚ but coronary heart disease is also costing the United States a lot of money. Since much of the population
