Introduction: What is Blood Pressure? Blood Pressure can be defined as the force per unit area exerted on a vessel wall by the contained blood in the heart‚ and is measured by millimeters of mercury (mm Hg) (Marieb‚ 703). Each time the heart beats (which is about 60-70 times a minute at rest); it pumps out blood into the arteries. There are two types of pressure recorded that can determine your blood pressure. Your blood pressure is at its highest when the heart beats‚ pumping the blood. This is called

plays a crucial role in pumping blood‚ nutrients‚ and respiratory gases throughout the body. Blood pressure is the force that pushes blood against the blood vessel walls and delivers these essential elements to the body. The highest pressure is when the artery is maximally stretched and is recorded as the systolic pressure. The lowest pressure occurs when the artery recoils and is relaxed is known as the diastolic pressure. Mean arterial pressure is the average blood pressure and is an indicator on

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

synthetic blood samples through a process called blood typing. According to Fredrick H. Martin‚ PhD.‚ et.al‚ blood typing is a test that determines a person’s blood type by checking the blood for the presence or absence of specific glycoprotein called antigens found on the surface of the red blood cells. The two clinically relevant antigens are the A antigen and B antigen. The blood type is named based upon which antigen is present on the surface of its red blood cells. There are four blood types.

From the experiment‚ the blood glucose concentration for Patient A is 5.6 mmol/L(Refer to Table 1). The blood glucose level for Patient A is normal as 5.6mmol/L is in the normal range. Urine sample from Patient A was tested and it is shown that there was no glucose and sodium present. The results showed that Patient A is healthy and could act as a control in this investigation. Secondly‚ patient B is suspected to suffer from diabetes mellitus. The blood glucose concentration for Patient B is 111mmol/L
