Lab 1: Heart Rate Lab (Revised Fall 2010) Lab 1. Heart Rate‚ Physical Fitness‚ and the Scientific Method Prelab Assignment Before coming to lab read carefully the following pages on the scientific method and then answer the prelab questions at the end of this lab handout. Be prepared to discuss and/or hand in your responses to the prelab questions at the start of lab. Introduction Biology is a dynamic field of study whose aim is to unravel the mysteries of life itself. Throughout history‚ humans

Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

The Human Heart Rate Aim: To study changes in the rate of the human heartbeat. Introduction: Blood is sent pulsing through the body’s veins‚ arteries and capillaries with each beat of the heart. The circulation of blood through the body delivers oxygen and food to the cells and removes wastes. The cells cannot survive if circulation stops for even a small amount of time. With an increase in body movement there is an increase in the cell’s energy use and the heart rate must increase to pump

COFFEE USE - HEART RATE RESEARCH PROJECT COFFEE USE - HEART RATE Part 1 The study used for this project is a nursing and health sciences study. One particular healthcare facility is trying to determine if it is a good idea to provide coffee in the waiting room for the patients. There are several other facilities that serve tea‚ coffee‚ and water‚ so this health care facility wants to determine if there is sufficient evidence to show that coffee increases the patient heart rates. The question

Hypothesis: As the caffeine concentration rises‚ so does the mean heart rate of daphnia. Risk Assessment: In this experiment there are the following risks both for the human that carries out the experiment and the daphnia: ← The human that carries out the experiment should be cautious not to touch the lamp with wet hands since it uses electricity. ← Also‚ be careful not to spill any of the pond water on the floor. ← As for the daphnia‚ there is a chance for them to die as when

The affect of psychological stress on the heart rate. Introduction: The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential‚ at the moment‚ immune and digestive systems. When the body is ready for a challenge‚ heart rate increases‚ blood pressure rises and glucose production intensifies to supply large amounts of energy. These metabolic changes are caused by release of stress hormones (catecholamine

Heart Dissection September 30‚ 2012 Introduction/Purpose In this lab experiment‚ I examined a pig’s heart and compared it to a human’s heart. The pig’s heart is very similar to a human’s heart by having the same structures‚ veins‚ valves‚ and chambers. I was unable to perform hands on examination on a human heart so I examined a pig’s heart. I was able to identify major areas of the heart and dissect it to examine the inside chambers and valves. This

on cardiovascular functions such as pulse rate‚ pulse lag‚ the PT interval‚ the TP interval‚ systolic‚ and diastolic blood pressure is noticeable after running down the steps of Long Hall and back up to the third floor. As Table 1 shows‚ the data support the initial hypothesis that the pulse rate will increase‚ the pulse lag will decrease‚ both the PT and TP intervals will decrease‚ and the systolic and diastolic blood pressure will increase. The pulse rate mean before exercise was about 78 beats per
