Introduction: Heart rate and blood pressure are key factors in determining overall physical health. Together they establish how well the cardiovascular and circulatory systems are functioning‚ which is important in engaging in appropriate exercise safely. It is important to know and understand the resting vitals of an individual to establish a baseline of what is within normal ranges for that individual. We take resting vitals to ensure that physical activity does not cause any undue stress that

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.

The effect of different music styles on blood pressure Experiment by: Claire Mouser and Garrett Swearingen Written by: Claire Mouser Written: 3/13/14 Abstract: The purpose of this experiment was to inform teenagers about the effect different genres of music can have on your heart rate. The heart rates of teens are affected differently when they listen to rock versus classical music. The goal of this experiment was to find out whether teens heart rates would change while they listened

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar

purpose of this lab is to isolate a bacterial population from the normal throat flora. A streak plate method will be used to obtain a pure culture of a Gram positive coccus genus of bacteria. Several biochemical tests will be performed to aid in the identification of this unknown bacterium. Biochemical tests are a series of tests used to identify certain bacterium The various tests that are used in this lab are the catalase test‚ oxidase test‚ blood hemolytic test‚ MSA‚ blood agar‚ and PEA/ab

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

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
