Alterations in Blood Flow and Blood Pressure Case 1 1. Explain the etiology and pathogenesis of atherosclerosis. 2. Describe where atherosclerotic plaques form in the body and list the possible consequences of developing plaques in those areas. Case 2 You have two patients with ulcers on their lower extremities. Patient A has ulcers caused by peripheral artery disease and patient B has ulcers caused by chronic venous insufficiency. 1. Describe the pathophysiology of how each

types of blood pressure‚ they are systolic and diastolic. When exercising both the heart rate and blood pressure increase. Oxygen consumption and heart rate increase during aerobic exercise to reach the demands of the intensity of the activity. This then means that the pulse rate will rise and the blood flow to the muscles increases. Systolic Blood Pressure – the highest pressure within the bloodstream. Which occurs during each beat when the heart is in systole (contracting) Diastolic Blood Pressure

for 2013 is high blood pressure. Hypertension (HTN) or high blood pressure‚ sometimes called arterial hypertension‚ is a chronic medical condition in which the pressure in the arteries is elevated. This requires the heart to work harder than normal to circulate blood through the blood vessels. Blood pressure is summarized by two measurements‚ systolic and diastolic‚ which depend on whether the heart muscle is contracting (systole) or relaxed between beats (diastole). Normal blood pressure at rest is

causing high glucose‚ also called sugar‚ content in the bloodstream because the pancreas no longer produces insulin or the cells of the body are no longer metabolizing the insulin the pancreas produces. So in this case homeostasis cannot occur. The primary symptoms of diabetes are increased thirst‚ frequent urination‚ and high levels of sugar in the blood or urine. Other symptoms include dry mouth‚ irritability‚ unusual weight loss‚ and extreme hunger. Over time‚ the high blood glucose

Hypertension‚ also referred to as high blood pressure‚ is a condition in which the arteries have persistently elevated blood pressure. Every time the human heart beats‚ it pumps blood to the whole body through the arteries. Blood pressure is the force of blood pushing up against the blood vessel walls. The higher the pressure the harder the heart has to pump. Hypertension can lead to damaged organs‚ as well as several illnesses‚ such as renal failure (kidney failure)‚ aneurysm‚ heart failure

your blood pressure. The most common way is to use a blood pressure machine or monitor. The doctor normally takes an inflatable cuff and put it around your arm. The machine gets turned on and the cuff begins to tighten a little around your arm. While the cuff is tightening the machine is checking your blood pressure. Once the cuff deflate‚ it is done checking your blood pressure. There are two numbers that shows up on the monitor screen. The top number takes measurements of the pressure in the

signal to take in fluid when water levels are low or salt concentration is high. The body produces two hormones‚ antidiuretic hormone (ADH) and aldosterone‚ to help maintain hydration. Antidiuretic hormone is released by the pituitary gland in the brain to signal the kidneys to retain water. When ADH causes water reabsorption from the kidney tubules‚ the salts and wastes are concentrated in what will eventually be urine. High level of ADH secretion and water retention happen when dehydration causes

your blood pressure. Hypertension is a chronic medical condition where the pressure of blood in the arteries is elevated. Blood pressure is a measure of the force that blood pumps against the walls of the arteries‚ and will have two readings: the systolic pressure or the measure of the blood within the artery when the heart muscle is contracting‚ and the diastolic pressure or the pressure of the blood when the heart muscle is relaxing. It is read as systolic pressure over diastolic pressure. Hypertension
