Brachiocephalic artery

Matt Lundgren SOC 221 January 26, 2016 Hypertension and Social Ecology Hypertension is a chronic medical condition in which an individual’s blood pressure is too high. This means that the blood is exerting more pressure on the arterial walls than normal as it moves throughout the body. I chose to write about this disease because numerous members of my family suffer from hypertension, or high blood pressure, and it is especially interesting to me because of the fact that hypertension itself…

The initial electrical impulse that begins the process of a heartbeat is generated by a group of cells located in the upper chamber of the heart. This special pathway is as follow: the sinoatrial node, atrioventricular node, his-purkinje network. The impulse starts in a small bundle of specialized cell which is known as the sinoatrial node located in the right atrium. The sinoatrial node sets the rate and rhythm of the heartbeat. The atrioventricular node slows the electrical signal before…

wave velocity (PWV) increases more with age than the carotid-radial PWV. This is due to the reduction of elasticity in central arteries; the PWV of these arteries is included in the carotid-toe measurement but not the carotid-radial measurement. First of all, the propagative model of the circulatory system is used when examining PWV. This model consists of distensible arteries that end with resistance vessels, whose distributed elastic properties allow the generation of a pressure wave that…

time in a hypovolemic state the kidneys are unable to maintain a glomerular filtration rate (GFR) despite a compensatory response leading to a decreased filtration rate and pressure (McCance & Huether, 2014). Examples of prerenal injury are renal artery thrombosis or hypotension secondary to hypovolemia caused by dehydration or hemorrhage in addition to shock either septic or cardiogenic (McCance &Huether, 2014). There the possibility…

need to be conducted in order to confirm a diagnosis. Congestive heart failure is a condition of the hearts muscles failing to pump the necessary blood for the body to function (Mayo Clinic, 2017). For example, coronary artery disease is a condition involving the hearts arteries becoming narrow…

A major symptom of heart disease is exercise intolerance, which is thought to be caused by overactivation of the sympathetic nervous system (SNS) via limb edema stimulating group III/IV afferent feedback mechanisms (Figure 1) (7, 8 & 9). Accurately replicating the afferent feedback during exercise is difficult in both healthy and diseased subjects, due to an inability to directly measure afferents in human subjects. Thus most information about the response of afferents comes from post-exercise…

Population and Health Issue High blood pressure according to MayoClinic is a common condition in which long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such has heart disease ( www.mayoclinic.org). However, hypertension commonly know has high blood pressure is much more common in the African American community. There was a study done in an urban ambulatory internal medicine clinic in southeast Michigan. Enrolled in the study…

Congestive Heart Failure (CHF) is characterized by a decrease in cardiac output (CO) and the consequent decrease in blood flow throughout the body leads to many widespread effects. For example, when CO is too low, the body starts to prioritize and will decrease blood flow to certain organs, such as the digestive viscera, in order to maintain needed blood flow in organs such as the brain. As a result, a person with CHF will have issues with cachexia and malnutrition because the body is not…

Scleroderma is a rare disease that causes the skin to become thick and hard. It’s a rare disease that can be life threatening. More than 75% of people that get this chronic disease are women. There are usually two types of scleroderma, localized and systemic scleroderma. Localized scleroderma usually only affects the skin, and systemic scleroderma is more serious. It affects the skin, muscles, blood vessels, and organs. The cause of scleroderma is unknown and there is no cure for this disease at…

chances of getting a heart disease increases threefold. Gender wise, men are more prone to develop a cardiovascular or heart disease than women. Of all the deaths caused by heart diseases, 80% among men and 75% among women are due to Stroke and Coronary Artery disease. Higher intake of saturated or mono saturated fat is also associated with higher risk of developing a cardiovascular disease, with the exception of French!…
