Pathophysiology of Coronary Artery Disease Atherosclerosis is a type of arteriosclerosis caused by a build-up of plaque in the inner lining of an artery. (Arteriosclerosis is a general term for thickening or hardening of the arteries.) (Porth 2005) Plaque is made up of deposits of fatty substances‚ cholesterol‚ cellular waste products‚ calcium‚ and fibrin‚ and can develop in medium or large arteries. The artery wall becomes thickened and looses its elasticity. (Fraser 2000) The wall of an artery

Pathophysiology Paper Pathophysiology of Congestive Heart Failure I. Description: Congestive Heart Failure is more of a syndrome than a disease. Heart failure may be classified according to the side of the heart affected‚ (left- or right-sided failure)‚ or by the cardiac cycle involved‚ (systolic or diastolic dysfunction). (Schilling-McCann p. 176). The word "failure" refers to the heart’s inability to pump enough blood to meet the body’s metabolic needs. (Schilling-McCann p. 176). When the heart

This particular job did not require us to attend under emergency response‚ this immediately made me feel relaxed and able to focus on my existing knowledge of respiratory pathophysiology. I foolishly had not anticipated any real worries or concerns‚ as it appeared to be a straightforward transportation from GP surgery to hospital. On arrival I was surprised to find the patient unattended and untreated in a room with no HCP present. I felt extremely concerned there had been no monitoring performed

Cancer Patho Definition: uncontrolled growth of abnormal cells in the body Pathophysiology: The term cancer refers to a malignant tumor; a tumor that grows rapidly‚ isn’t encapsulated‚ invades local structures and tissues‚ is poorly differentiated‚ has rapidly dividing cells‚ and can spread distantly through blood vessels and lymphatics. These malignant tumors are made of tissue that overgrows and is independent of the body’s governing systems. Cancers are termed according to the cell type from

Pathophysiology Exam 1: Immunity Objectives 1) Describe the cell functions of the Immune System: Lymphocytes- small white blood cells that are responsible for much of the work of the immune system. Three types: Natural Killer Cells-NK cells provide rapid responses to virally infected cells and respond to tumor formation. NK cells are unique bc they have the ability to recognize stressed cells in the absence of antibodies and MHC‚ allowing for a much faster immune reaction. Trigger phagocytes

Anatomy and Physiology 1. Bone – Bones are made up of different types of tissues and join together to form the skeleton of the body. Their primary purpose is to provide structure for the body and to protect organs. It also serves as a storage site for minerals as well as producing and storing blood cells. The three different tissues that bones are composed of are: a. Compact Tissue – The dense outer tissue in a bone. b. Cancellous Tissue – The sponge like tissue inside the

COM155-University of Phoenix COPD and Heart Disease Chronic Obstructive Pulmonary Disease (COPD) and heart disease are two of the deadliest chronic illnesses affecting the world’s population. These diseases have caused hundreds of thousands to lose their lives. With the death rate of heart disease and COPD rising‚ attention should be focused on these diseases and how we can prevent fatalities throughout the world. Educating the public about these diseases is vital in lowering the
