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

Pathophysiology. Thyroid hormones assume a vital role in the normal functioning of the body. Insufficiency in secretion from their source to respond to body needs in the body risks infection of hypothyroidism. They are secreted by the thyroid glands which are located in a close-range to the trachea between the cricoid cartilage and suprasternal notch where they possess two joined lobes by an isthmus. In addition‚ the thyroid hormones are inconclusive of triodothyronine (T3) and thyroxine (T4) that

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

An In-Depth Look at Portal Hypertension Portal Hypertension (PH) is an increase in the pressure within the portal venous system. The portal venous system is a network of veins that carry blood from the digestive organs to the liver. The most common cause of PH is cirrhosis of the liver. Cirrhosis is an advanced stage of liver scarring called fibrosis. This impedes the liver’s ability to function. PH caused by cirrhosis can often lead to the restored patency of a certain ligament of the liver called

CHAPTER NO.1 INTRODUCTION HYPERTENSION: INTRODUCTION: This means abnormally elevated blood pressure. It may refer to increase blood pressure in any blood vessels‚ such as pulmonary or portal hypertension. However‚ it usually refers to an elevated systemic arterial blood pressure. Hypertension is not a disease but physical finding. 1.1 DEFINITION: Hypertension may be define as either a sustained systolic blood pressure (SBP) of greater than 140 mmHg or a sustained diastolic

Transmission and epidemiology of MRSA: current perspectives Maggi Banning Abstract Staphylococcus aureus is a Gram-positive bacterium that developed resistance to the penicillin derivative tnethicillin. Subsequently‚ methicillin-resistant S. aureus {MRSA) emerged as a bacterium that became less susceptible to the actions of methicillin and thus developed the ability to colonize and cause life-threatening infections. Globally.‚ MRSA continues to cause hospital-acquired infections which are becoming

How would you develop a realistic plan to help this patient reduce his blood pressure and prevent complications? Primary hypertension affects millions of people in the United States and billions around the world. Furthermore‚ it is likely to be the most common all health problems among adults and the leading cause and risk associated with cardiovascular complications. Multiple factors are known to contribute to the development of this cardiovascular disorder‚ some of them are modifiable and have

The HUMAN BODY PLAN: STUDY of ANATOMY and PHYSIOLOGY THE HUMAN BODY PLAN The human body begins to take shape during the earliest stages of embryonic development. While the embryo is a tiny hallow ball of dividing cells‚ it begins forming the tissues and organs that compose the human body. By the end of its third week‚ human embryo has bilateral symmetry (a body plan in which the left and right sides mirror each other) and is developing vertebrate characteristics that will support an upright

Pathophysiology of Schizophrenia and Dementia Schizophrenia currently is conceptualized as a broad syndrome expressed by a heterogeneous group of brain disorders rather than as a single disease entity. In addition‚ schizophrenia is viewed as the most severe end of a spectrum of schizophrenia-related disorders. Although placed in the category of "functional" psychiatric disorders‚ schizophrenia is associated primarily with abnormalities of brain neurochemistry‚ neuroanatomy‚ and development. Genetics
