What factors affect heart rate

Download file to see previous pages... The heart is an essential and delicate organ of all humans plus animals. This is due to its primary functions, which are indispensable in executing diverse roles and keeping other organs working normally. Mainly, there exists numerous factors, which affect heart functions in diverse ways, but not all of them result in serious life threatening incidences. These factors usually differ radically due to their diverse influences on the heart rate due to their intensities. Principally, heart rate or pulsation is the speed in which it contracts so that it may be able to sustain adequate blood circulation for effective supply of oxygen in all the body tissues. Normally, a healthy person has an average pulsation of 70 – 80 Beats per minute (Bpm), though this owing to certain factors might change. For instance, when the body requires more O2 in its tissues, then the pumping of extra blood is necessary which facilitates more O2, hence escalating pulsation. Hypothesis: Diverse breathing modes held per minute normally impart noticeable heart pulsation fluctuations. Since, during inspiration it slows down prior resuming to the normal beating (Camm 3). The fluctuations differ drastically depending on the breathing alterations per minute, which is the key exemplification of this report. Heart rate of an individual or any animal is directly comparative to the breathing. Method The experiment implicated measuring of heart rates or pulsation per minute by having diverse breathing modes. This entailed five trials data measuring and recording to ensure attaining of high accuracy during the process, for each set. The independent variable was breathing where for this case to attain reliable results where breathing modes ranges; Normal breathing Holding breath Deep breathing The dependent variable, which will be varying in each set, is the heart rate, where to guarantee its accuracy there is a need for several five recordings per minute. Procedure: Initial set involved taking normal breathing pulsation using heart rate monitor per minute and tabulating the five trials in a table prior computing the averages (Telles, Nilkama & Acharya 3). This entailed keen observation meant to ensure consistency of the data. Second measurement encompassed holding the breath for a long period as one would, then tabulating the data within one minute five times to complete the set and calculate the mean. Third set involved breathing deeply for one minute and compute as other sets before taking the average, then followed by computation of the five trials from the three sets. Lastly, there was compiling of the whole class individual records for the three sets coupled with final calculations. Final computations encompassed mean, median standard deviations, modes and diverse graphs to depict their correlations clearly (Telles, Nilkama & Acharya 2).

Heart diseases risk factors

This paper examines the relationship between three physiological risk factors, i.e. stress, depression, and anxiety, and their effects on heart disease. This research revealed that three physiological response mechanisms are multi-dimensional where one has an effect on leading or causing the other response and the other response being caused by it.

Heart Circulation
Stroke volume (SV) is the amount of blood being pumped by the heart per each contraction, which is about 70mL in a resting man of average size in supine position (Ganong, 2003). Cardiac output (CO) is the amount of blood ejected by the heart per minute, defined in the equation CO = SV x HR.

Rate of Glucose Uptake by Yeast Cells
When Benedict's reagent (Cu2+-citrate ion complex) is added to the glucose solution and then heated, a reaction occurs (Ege, 1994). In this reaction, glucose is oxidized to gluconic acid (exists as the gluconate ion in basic condition), while the Cu2+-citrate ion complex is oxidized to a red precipitate of Cu2O as shown in Equation 1.
