  • Heart Rate Experiment - 319 Words
    Heart Rate Experiment Introduction: The heart rate measures the contractions of your heart and is a requirement for life. The heart uses four chambers. The right and left-lower chambers are called ventricles, and right and left-upper chambers are called atria. These four chambers complete two cycles that replenish the tissues with oxygen and get oxygen from our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This...

  • Effect of Caffeine on Heart Rate in Daphnia
    Practical 1.1 Introduction: Caffeine belongs to a class of compounds called methylxanthines and can block a receptor on the surface of heart muscle cells for adenosine. In fact, it is caffeine's blockade of the A1 adenosine receptor in the heart that causes the heart to pound after a significant caffeine dose. Caffeine and similar compounds also inhibit a class of enzymes known as cyclic nucleotide phosphodiesterases. These enzymes are, in part responsible for degrading a stimulatory signal...

  • Heart Rate Before and After Exercise
    Introduction: Heart Rate is defined as the amount of times a person's heart beats in one minute. A resting heart rate is the person's heart rate prior to any activity or exercise. As activity increases, the heart rate will increase in speed. An increased heart rate is essential as it replaces oxygen in the muscles that is used during said activity and gets rid of excess carbon dioxide through the blood stream. Blood pressure is the force of the blood pushing on the walls of the veins and...

    Aim: Pulse rate is the number of times in a minute an artery pulsates or the rhythmic expansion and contraction, which indicates that a heartbeat has occurred. There are many factors which affect the pulse rate which includes: gender, age, body temperature, pain, emotion, exercise, blood pressure, consumption of stimulants, dehydration, body mass index (weight), fitness level, lifestyle and many more. In my investigation, I would be examining the affect of gender in the change in the pulse...

  • How does music affect your heart beat??
    The heart is a vital organ in the human body. Though only the size of the fist, it pumps blood to the rest of the body by rhythmic expansion and relaxation. The frequency of this cardiac cycle is measured by the term heart rate. The heart rate is the number of contractions (beats) of the heart in a minute. The heart rate tends to increase with response to a wide variety of conditions like vigorous physical activity or according to our hypothesis, music. Music has an arousal effect which is...

    To investigate the effect of different caffeine concentration on the heartbeat rate of Daphnia at room temperature. Introduction: Caffeine is found, and produced in many plant species to function as a natural pesticide, and as an inhibitor of seed germination of other nearby coffee seedlings to give it a better chance of survival. Caffeine is able to paralyze and kill certain insects upon feeding on the plants that produce caffeine. Coffee, tea and cocoa are common...

    Heart rate measurement indicates the soundness of the human cardiovascular system. This project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood. It consists of an infrared LED that transmits an IR signal through the fingertip of the subject, a part of which is reflected by the blood cells. The reflected signal is detected by a photo diode sensor. The changing blood volume with heartbeat results in a...

  • Measuring The Effect Of The Concentration Of Caffeine On Heartbeats
    Measuring the effect of the concentration of caffeine on heartbeats. Caffeine is a stimulant which increases cardiac arrhythmia (improper heart rate) by increasing stress hormone (e.g. adrenaline) secretions. It also increases blood pressure which contributes to the blockage of receptors such as adenosine A1 and A2 receptors. The caffeine blocking receptors also blocks vasodilatory function, in which blood vessels become less dilated. Hence wise, caffeine is also known as a mild stimulant of...
