Mechanisms of Blood Flow in the Human Forearm during Mental Stress‚ Following Isometric Exercise and after Occlusion ------------------------------------------------- 1. Introduction A common technique in measuring blood flow in the human forearm is by venous occlusion plethysmography. The fundamental principle is that if the venous return from the arm is blocked‚ the forearm will swell at a rate relative to the rate of the arterial inflow (Whitney‚ 1953). However‚ the rate of increase in volume

between Venipuncture and Fingerstick Methods as Blood Collection Technique for Complete Blood Count In Laboratory Medicine‚ evaluation of Complete Blood Count is essential to determine the patient’s health. Obtaining blood sample is done by different blood collection techniques‚ specifically‚ the venipuncture and the fingerstick method. Venipuncture is achieved by inserting a hypodermic needle to the median cephalic vein to obtain venous blood while pricking the fingertips with a sterile lancet

A person can be affected with blood disorder at any time in life‚ lifestyle‚ family history and some symptoms are always in which blood disorders are identified.

Hypertension Hypertension also known as high blood pressure is a common condition in which the force of the blood against your artery walls is high enough that it may eventually cause health problems‚ such as heart disease. Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries‚ the higher your blood pressure. High blood pressure is the leading cause of stroke and a major

monitoring blood pressure readings. Hypertension is the medical term for high blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood (National Institute of Health‚ 2012). High blood pressure is a serious medical condition because it causes the heart to work harder. It is particularly dangerous because it often has no warning signs or symptoms. Blood pressure includes systolic and diastolic pressures; both numbers in a blood pressure

step in preventing and treating high blood pressure is a healthy lifestyle. You can lower your blood pressure with the following lifestyle changes: Losing weight if you are overweight or obese‚ quitting smoking‚ and eating a healthy diet‚ including the diet dash (eating more fruits‚ vegetables‚ and low fat dairy products‚ less saturated and total fat). Also‚ reducing the amount of sodium in your diet to less than 1‚500 milligrams a day if you have high blood pressure‚ getting regular aerobic exercise

untreated hypertension. Hypertension is the term used to describe high blood pressure. Blood pressure is a measurement of the force against the walls of your arteries as the heart pumps blood through the body. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as two numbers -- for example‚ 120 over 80 (written as 120/80 mmHg). One or both of these numbers can be too high. The top number is your systolic pressure. * It is considered high if it is over 140 most of the

known as high blood pressure is 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

of a normal environment in which bodily systems are able to function most efficiently. The importance of homeostasis can be seen in blood pressure and pulse rate‚ as measurements which are not in the normal range can create serious health problems. Exercise has a known effect on both of these systems‚ as it results in a rise in body temperature and dilation of blood vessels‚ as well as an increase in breathing rate. By measuring how these rates return to normal levels after exercise demonstrates
