Breathing Rate Lab Report

Change in respiratory rate during exercise
Aim:
To record and investigate how the breathing rate varies for the duration of light and heavy exercise.
Introduction:
When an individual exercises, the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart, and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together, which is named the respiration system. The organs involved with the respiratory system include the sinuses, trachea, bronchial tubes, diaphragm and capillaries. When we inhale, oxygen enters the body through the nose or mouth then passes through the trachea (windpipe), which filters the air. (Science, Respiratory System: Facts, Function and Diseases, n.d.) The trachea branches into the bronchi, which are two tubes that transports air into each lung. The Bronchial tubes leads to the lobes of the lungs. The lobes are filled with small, spongy sacs called alveoli, and this is where the exchange of oxygen and carbon dioxide occurs (Science, Respiratory System: Facts, Function and Diseases, n.d.) Alveoli has tiny blood vessels called
This allows more accurate results after conducting the experiment, as of an uneven amount of time or different exercises will produce varied results. The dependent variable in this experiment is the respiration rate of the subject after a period of exercise and a period of rest. The respiration rate of the subject during various intensities. The length of time given for the person doing the light and heavy exercise, the person doing the exercise and the exercise being done for light and heavy exercise are all constant over both trials. This is because in order, to collect accurate data, we perform two trials that have the same
