  • Heart Rate - 504 Words
     The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist, the inside of your elbow, the side of your neck, or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for...

    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...

    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...

    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...

  • 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...

  • 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...
