of changes in blood pressure (leading to resultant changes in blood vessel diameter): Baroreceptors at the carotid sinus (the bifurcation of internal and external carotid arteries in the neck) and the aortic arch detect changes in blood pressure. These non-encapsulated nerve endings‚ located in the adventitial layer of arteries‚ are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure. Afferents from the carotid region form the fine carotid

WHAT ARE THE HEALTH BENEFITS OF EXERCISE? Physical exercise is very important for a healthy body. To stay healthy and fit‚ we need to exercise regularly. Most people believe that exercise and work are the same. They believe that if they exert effort‚ flex their muscles during work‚ it is already an exercise. But exercise and work are not the same thing. Although both expend energy‚ exercise has an element of pleasure. When you work‚ you become tired‚ the same as when you exercise. But in exercise

A friend of mine referred me to a chiropractor. “What can a chiropractor do?” I asked myself. Despite

Variables Affecting Human Arterial Pressure and Pulse Pressure BIOL 204-506 Remi Ben-Davies Dashaun Lee‚ Amanda Easter‚ and Lynne Baker April 9th‚ 2015 1 Introduction: Purpose: The purpose of this experiment was to determine how different variables may affect arterial pressure and pulse rate. Two subjects were used as models for the tests. The first two tests required the use of sphygmomanometers and stethoscopes to measure the arterial pressure and pulse rate. The last test required sphygmomanometers

Systolic and Diastolic Heart Failure Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart’s pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium‚ then on to the left ventricle‚ which pumps it to the rest of the body. The left ventricle supplies most of the heart’s pumping power‚ so it’s larger than the other chambers and essential for normal function. (American Heart Association). In left-sided

Cardiovascular system consists of the heart which pumping and transporting blood to the body through blood vessels which is the other part of the cardiovascular system. The blood vessels consist of veins‚ capillaries‚ and arteries. Each one of the blood vessels has a specific function such as arteries which transfer the blood from the heart to the whole body‚ and veins which have the reverse process which carries the blood back to the heart. This is a simple definition of cardiovascular system. Then this essay

is determined by the force‚ heartbeat rate‚ and resistance to blood flow through vessels. Cyclic changes in arterial blood pressure are partially attributed to the rhythmic contractions in the left ventricle (Iaizzo‚ 2009). The pressure within the arteries reaches its highest level (systolic pressure) during systole and reaches the lowest level (diastolic pressure) during ventricular diastole. Blood pressure is decreased to about 30 to 40 mmHg at the entrance of the capillaries and then reduces to
