Measurments of boby temperature, heart rate and breathing rate

Introduction

Saira Iram Shaukat Unit 5- Senzenni Assignment 5-P6 Measurements of body temperature, Pulse rate/heart rate 1) Introduction: For this assignment I have been asked to write up a report on the experiments that we c `1qarried out. The experiments were to measure our breathing rate, pulse rate and body temperature. I will also be showing my results after all these experiments in a graph and I will be explaining the method of how we carried each of the experiment out in a safe practise way. 2) Method used: The first experiment that we done were measuring our pulse rate. We used a stop watch to make sure the timing was accurate for each time we performed it. A member in my group checked my pulse rate by putting their index finger and middle finger on the inside of my wrist, at the beginning of this we started the stop watch and done this for 15 seconds. This measurement was classed as At rest point. After we done this I done exercise for 5 minutes. I jogged in the same pace around the classroom. Once I done the exercise I got my pulse checked again I done this for 15 seconds like before. I recorded the results in a table. After 2 minutes I checked again and again after 3 minutes following onto 4 minutes. Throughout this I made sure I recorded my results straight away in the table so that it would be accurate. ...read more.

after 1 minute, 2 minute etc. We used the same equipment to check the time which was the stop watch. 3) Results in table format Time Breathing rate (per min) Body temperature in Degrees Celsius Pulse rate (beats per min) At rest 16 37 88 1 minute 52 37.5 124 2 minutes 36 37.3 92 3 minutes 28 37.2 44 4 minutes 20 37 84 Interpret the data obtained, including the cardio respiratory fitness data, by stating and explaining. Once I had done al 3 experiments I put them all together into one table(above) and made a line graph, by doing this it makes it clearer for me to see my results and to see how well I done. Starting with pulse rate, I checked my pulse rate at rest before any exercise my table shows that my pulse rate was 88 beats per minute which is roughly average for any person even though my peers was lower than mine. Once I had done my exercise I checked my pulse rate again after 1 minute, I felt at this point my heart beat was very fast therefore my pulse rate was highest here it was 124. I had to check again after 2 minutes it then went lower than before and told me the result which was 92. After 3 minutes I checked once more, here I felt that my heart beat was going slower as I was resting my results told me it was 44. ...read more.

Conclusion

with through the overall performance were most likely to be valid as when we put them into a graph it made perfect sense and was very clear to us and our teacher as she said they were good However there may have been a few factors that may have affected the reliability of our results: * Time-This was the most important in all 3 experiments and we used a stopwatch to time everything we needed to therefore it should have been accurate. From our knowledge and understanding it was right but may have been a few minutes early or later which slightly affected our results. * Another may have been when we checked our body temperature we used a thermometer. The first one we used was apparently not working right we saw this from our first set of results as they were going the opposite direction to the average results. We showed our teacher and she said to use another thermometer so we did so and our results were much more better however there still may have been some inaccuracy. * The first experiment we done was checking our pulse rate, we had to work in a group of 3 which meant some one else had to check your pulse rate. As it was some people's first time they may not have known how to do this or were a little unsure therefore the results may have not come out as accurate as they should have been. ...read more.

***
A clear account of the practical work but the biological knowledge and understanding shown is fairly superficial.

    However it is not a significant increase. This suggests that the enzymes are still not quite at their optimum temperature. However as was the case at 30�C there is an increase in energy which causes yet more collisions and allows the enzymes to work more efficiently.

    The maturing follicles then release another hormone, oestrogen. As the follicles mature over a period of about seven days, they secrete more and more oestrogen into the bloodstream. Oestrogen causes the lining of the uterus to thicken. When the oestrogen level reaches a certain point it causes the hypothalamus to release Leutenising Hormone Releasing Factor (LH-RF)

    Pipettes are a fast way to measure the solution with a limited amount of time, it is a suitable and vital piece of apparatus however there might be a probably with used pipettes as they can have dents from previous experiments and would only be accurate to around 0.0ml-0.2ml when measuring solutions.
