Zurus Siddiqui The Respiratory System Introduction Cells in the body require oxygen to survive and the body requires a continuous supply of oxygen to carry out its vital functions. The respiratory system exchanges gases through the alveoli in the lung and distributes oxygen through the cardiovascular systemic circuit to the different parts of the body and their tissues.
Our activity was to jump on the same place for 15s seconds. I measured the testpersons heart rate by putting a finger on the neck and controlling how many times the heart beats in 15s.
I measured the testpersons breathing rate by counting how many times they exhaled in 15s by holding a hand in front of the persons mouth around 20 cm away. The testpersons jumped on the place for 15s. I measure the heart rate as in 1 I measured the breathing rate as in 2.
I multiplied all results that I measured in 15s by 4, so I got the results per minute 60s instead. The aim of this lab was to find out how activities affect the heart and breathing rate in a human. In my lab, I can easily see that the heart and breathing rate become higher during activity.
I measured for 15s and then I multiplied it by 4. If I would make a more accurate lab, I would measure in 60s. Or if even more correct, I could measure for s and divide by 2. It would be more accurate if I did like this, because when I measured for 15s and multiplied it by 4, it might be up to 2 heartbeats wrong when I started to measure and up to 2 heartbeats wrong in the end, then I multiply it by 4, so I could get up to 16 heartbeats wrong per minute.
But if I measure for 60s, it could be up to 2 wrong in the beginning and up to 2 wrong in the end, which would mean that I would only get up to 4 heartbeats wrong per minute.
If I would do the lab even more accurate, I could use a professional pulse and breathing meter and have a treadmill for the testpersons to run on, so the testpersons would make exact the same activity.
In this lab the resting heart rate and the resting breathing rate were much higher than normal. The persons was probably not relaxed.
So in next lab I would make sure that the persons are relaxing. It would be interesting to measure the heart and breathing rate on a smoker or a person that has certain health problems as eg.
In these persons, the gas exchange is slower, and smoking also has that negative effect that the hemoglobin can bind less oxygen because of it is occupied of carbon monoxide CO. So if I would make a new study with persons in this group, I would probably get the results that their heart will beat faster and they will have much harder to make exercices.
For example alcohol depresses both heart and breathing rate, which makes it harder to make exercices. Some drugs medicines can change the heart rate or make it easier to breath, eg. Other drugs as nitroglycerine is used in angina pectoris and it makes the arteries around the heart becoming broader and let more blood pass to the heart and lower the heart rate.
If there is too big excess of energy sources, one become fat. Fat people have more mass and weighs more than not fat people, so they also need more energy and oxygen to do activities. Too much fat in the diet stops muscle cells to take up glucose from the blood and makes the cells to slow down the release of needed energy.Anatomy Of The Respiratory System Lab Report.
Phoenix Material Roderick Tabigne Respiratory System Lab – Week Six Introduction The respiratory system consists of the upper respiratory tract (the nasal cavity, pharynx, larynx, trachea, and bronchi) and the lower respiratory tract (the lungs).

This essay discusses an analysis of Respiratory physiology.
In light of this significance, three experiments which are discussed in this report were conducted in order to assess the factors which affect the respiratory rate and interpret the findings and compare them. The organs of the respiratory system include the nose, nasal cavity, sinuses, pharynx, larynx, trachea, respiratory tree, and lungs.
They function to transport air to the air sacs of the lungs (the alveoli. Lab # Respiratory Physiology Background The respiratory system enables the exchange of O2 and CO2 between the cells and the atmosphere, thus enabling the intake of O2 into the body for aerobic respiration and the release.
