it is the cause of most friction of blood within the vessels (Marieb & Hoehn‚ 2016‚ pp.708). Peripheral resistance in general is explained as the resistance of blood flow within the vessels. For example‚ as the vessels (arteries) dilate‚ resistance decreases. Conversely‚ as arteries constrict‚ the peripheral resistance

a term that millions of us are familiar with. According to Center for Disease Control and Prevention “more than 65 million individuals have hypertension” ("High Blood Pressure"‚ 2010). Blood pressure is defined as the force of blood against the artery walls as it circulates through the body. It can cause health problems if it stays high for a long time. It is measured using two numbers. The first‚ systolic‚ number represents the pressure in your blood vessels when your heart beats. The second‚

throughout the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away from the heart‚ and veins carry deoxygenated blood back to the heart. This process is called circulation. The roles are revered in pulmonary circulation. The pulmonary arteries bring deoxygenated blood to your lungs‚ while the pulmonary veins will bring

Causes and Risk Factors A. Causes - The cause for coronary heart disease in the build up of plaque in the heart’s arteries. Your doctor may refer to them as hardening of the arteries. If the coronary arteries are blocked by fatty materials or other substances they are unable to successfully transport blood and oxygen to your heart. Because the plaque build up causes the arteries to narrow. If this happens it drastically slows the blood flow to the heart and can stop it altogether. B. Risk Factors

4. Joel feels little blood flowing to his hands and feet due to the vasoconstriction occurring. During this process the blood going to his extremities is being rerouting away from the dermal surface to a network of deep veins wrapped around deep arteries. When this occurs diffusion known as countercurrent exchange begins which traps heat closer to the body core and limits heat loss to the environment by reducing the temperature gradient between the arterial blood and the cold whether Joel is in.

giant (25 to 50 mm)‚ and super-giant (over 50 mm)(Brismanet al.‚ 2006). SIA‚ also known as ‘berry aneurysms’‚ appear as a round outpouching and are the most common form of cerebral aneurysm. Fusiform aneurysms represent a widening of a segment of an artery around the entire blood vessel‚ rather than just arising from a side of an artery’s wall. They can rupture but the chance is quiet low. Micro- aneurysms typically occur in small blood vessels (less than 300micrometer in diameter)‚ most often the lenticulostriate

Description: From the gross perspective the patient looks rather healthy. Grossly you can tell he had died from something like cardiac arrest or some type of stroke. But other than that we looked closely into the heart‚ lungs‚ coronary arteries‚ and brain.

He had ethybenzolecgonine in his system

Stress comes from many different things and is the cause of many problems in a person’s life. Stress management can be complicated and confusing because there are different types of stress. There are three main types of stress‚ acute stress‚ episodic acute stress‚ and chronic stress. Each has their own characteristics‚ symptoms‚ duration‚ and treatment approaches. Almost everyone has some type of stress. Some people cope with it better then others. Causes of stress are known as stressors. Stressors

diastolic pressure remains relatively constant when comparing with systolic pressure. Diastolic pressure is measured when both ventricles of heart relax and blood is refilling into the heart. As the volume of blood is fixed‚ the pressure created on arteries is nearly the same during diastole. 3. mean arterial pressure remain relatively constant The mean arterial pressure increases from 88.333 mmHg at rest to 91.667 mmHg during slight
