goal of this project is to test whether alcohol and caffeine has an effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart to beat

Is the stress-filled phenomenon that is adrenalin‚ coming straight from the adrenal glands travelling to the heart via significantly dilated blood vessels‚ stimulating a higher heart rate‚ while triggering a release of endorphins worth the risk? Worth the ‘risk’ that will all capture us eventually but still cripples fully grown men to a riverbank of tears and a prison of hidden emotional pain? Maybe‚ maybe not... This was it. My long

Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths

Adrenaline on the Heart Rate of Daphnia magna Hieu Duong 6 April 2011 Introduction The heart is a muscular organ that constantly pumps blood throughout the human body. The continuous flow of blood creates a system for vital organs within the body to gain oxygen and nutrients. The timely delivery of oxygen to the body’s organs is very crucial. Brain cells‚ for example‚ will die within minutes if the flow of oxygen is obstructed. For the blood to be pumped out of the heart and into the body
