The body system that most interests me is the cardiovascular system‚ I chose this system because I’m fascinated with how the heart works and how the blood flows throughout our whole body. The heart is a muscle that contracts which allows blood to be pushed throughout the body. The heart provides many nutrients and blood to the whole body along with many vital organs. The heart is spilt into four chambers: the right atrium‚ left atrium‚ left ventricle‚ and right ventricle. The blood flow starts in

majority of cases of cardiogenic shock occur within the subsequent 48 hours commonly due to reinfarction (Goldman‚ 2010). Other causes of cardiogenic shock include left ventricular failure‚ dysrhythmias‚ myopathies including valves‚ cardiac tamponade‚ pericarditis‚ pulmonary hypertension and pulmonary embolism (Ignatavicius‚ 2010). Pathophysiology Cardiogenic shock has a downward spiraling pathophysiology that ultimately leads to hypoxemia and

Identify the natural defense mechanisms of the respiratory system‚ and correlate changes in these defense mechanisms with respiratory dysfunction. 2. Describe effects of aging on the respiratory system. 3. Identify significant assessment data that should be obtained from a patient. 4. Describe pH and the mechanisms that regulate acid-base balance. 5. Describe the common

MICHAEL MENSAH FELBRY COLLEGE SCHOOL OF NURSING ANATOMY AND PHYSIOLOGY 102 MYOCARDIAL INFARCTION INTRODUCTION Myocardial infarction is the technical name for a heart attack. A heart attack occurs when an artery leading to the heart becomes completely blocked and the heart does not get enough blood or oxygen‚ causing cells in that area of the heart to die (called an infarct). Most heart attacks are caused by blood clots‚ which are in turn caused

The electrical activity of the heart: the electrocardiogram Electrical activity is a basic characteristic of the heart and is the stimulus for cardiac contraction. Disturbances of electrical function are common in heart disease. Their registration as an electrocardiogram (ECG) plays an essential role in the diagnosis and management of heart disorders. THE GENESIS OF THE ELECTROCARDIOGRAM Pathways of conduction and the electrocardiogram The sinus node is situated in the right atrium

Systemic Lupus Erythematosus Systemic lupus erythematosus‚ often known simply as lupus or abbreviated to SLE‚ is a systemic autoimmune disease or an autoimmune connective tissue disease that can affect any part of the body. As occurs in other autoimmune diseases‚ the immune system attacks the body ’s cells and tissue‚ resulting in inflammation and tissue damage. It is a hypersensitivity reaction of the type III variety‚ caused by antibody-immune complex formation. There are several explanations

The myocardium (cardiac muscle)‚ is the thickest section of the heart wall and contains cardiomyocytes‚ the contractile cell of the heart. 2. What part of the heart is the pacemaker and why? The SA Node is located in the right atrium of the heart. It is made up of a group of cells (myocytes) positioned on the wall of the right atrium‚ at the center of the heart and near the entrance of the

A magnetic resonance imaging test (MRI) uses magnets and radio waves to capture images inside your body without making an surgical incision. An MRI allows your doctor to see the soft tissues in your body‚ along with your bones. An MRI can be performed on any part of your body. However‚ a heart or cardiac MRI looks specifically at your heart and the adjacent vessels
