Oxygen Deficit Lab Report

Cari’s po2 is 54 mm Hg so therefore her lungs were working as if she was doing intense exercise although she wasn’t. Decreased oxygen saturation and PO2, decrease the efficiency of gas exchange between the arterial blood and tissues of the body.

There is a small amount of carbon dioxide and more oxygen in the body because of gases exchange this is where oxygen form the lungs is transferred in to the blood and carried to the heart and when carbon dioxide is carried in to the lungs forms the blood and is exacted outwards by breathing. Mitochondria also need oxygen to create carbon dioxide for the body so the gas exchange can happen again. Outside the body there is a smaller amount of oxygen but it is still higher than CO2.

Once oxygen is deposited into the bloodstream by the lungs, the body must also increase your heart rate to deliver oxygen to the cells to once again maintain homeostasis. The increase in

The lungs have a huge blood supply and a huge surface area so they are very effective at getting oxygen out of the air. They are also in charge of getting rid of the carbon dioxide excess and some of the excess water as water vapour. It is the lungs job to get the oxygen and the heart has to pump it around the rest of the body. Energy metabolism; when people are exercising their muscles are contracting and they are using more energy so they will need more oxygen getting to the muscles and my heart

This is important because you want this system working smoothly so that it efficiently responds to changing demands for oxygen, speeding up the rate when you are active and slowing it down when you are at rest.

The RER of both TRF groups was significantly higher during the feeding phase and significantly reduced during the fasting phase than their ad-lib counterparts. Using 45 mice, Chung and colleagues12 studied an 8-hour high-fat TRF diet over 27 weeks. RER was measured from 6 p.m. to 10 p.m., 10 p.m. to 6 a.m. (TRF period), and 6 a.m. to 6 p.m. RER for the ad-lib group was approximately 0.75 throughout the study. RER for the TRF group was 0.70 from 6 a.m. to 10 p.m. and increased during the TRF period. Comparing the two groups, the RER of the TRF group was significantly lower than the ad-lib group from 6 p.m. to 10 p.m., significantly higher than the ad-lib group during the TRF period, and similar to the ad-lib group from 6 a.m. to 6 p.m. In Moro et al.’s18 8-hour TRF study with 34 men, RER was measured between 6 a.m. and 8 a.m. At the end of the study, the RER decreased significantly in the TRF group compared to baseline (0.83 ± 0.02 to 0.81 ± 0.01). Yet the RER in the TRF group was the same as the ad-lib group (0.83 ± 0.02). Sundaram and Yan13 tested the impact of an 8- and 12-hour high fat TRF diet on RER in mice. The diurnal rhythms of RER oscillations of the TRF groups (ranging from about 0.9 to 0.75 between the feeding and fasting cycles) were improved compared to the high-fat ad-lib mice.

In addition to size, stress may also influence the metabolic rate, because a mouse consumed more oxygen per minute when it was first put into the cage. This is because the handling disturbed and stressed the mouse. However, after a few minutes, the rate of oxygen consumption decreased because the stress level

3. “The second wind” phenomenon consists of 10-minute premature muscle fatigue and muscle soreness. During this phenomenon, the heart rate increases, displeasing myalgia, and shortness of breath occur. These symptoms occur due to low levels of glucose and free fatty acids. Also, the oxidative phosphorylation increases as well.

Judging from their basal metabolic rates (an indicator of thyroid function), categorize the rats as hypothyroid (low thyroid

The purpose of these experiment is to understand the coordination of cardiovascular and respiratory systems in controlling O2 and CO2 and acidity of the blood. As the heart rate is affected by the resting respiratory, the first hypothesis is when the heart is in the opposite side of its target cells, heart rate and blood pressure will increase. According the higher muscle oxygen need when exercise than normal, the second hypothesis is heart rate will increase when exercise and after that will subsequently return to baseline levels. The last hypothesis is that there is an obvious decline in heart rate during inhalation compared to exhalation.

Myoglobin is an oxygen-store protein found in muscle. Like hemoglobin, it frames a free blend with oxygen while the oxygen supple is good, and stores it until the need for oxygen increases. Therefore muscle has its own implicit oxygen supply. Be that as it may, when exercising the oxygen from myoglobin is immediately spent after activity, extra oxygen is required to pay back any oxygen that has been obtained from myoglobin

Oxygen is required by the cells to carry out respiration, this provides the energy in the form of adenosine-triphosphate (ATP) which is a molecule required for muscular contraction. As exercise takes place, oxygen is used

To start off the experiment, a baseline was needed in order to be able to compare the different variables through out the experiment. The subject was instructed to sit and relax quietly while the blood pressure cuff and pulse plethysmograph were placed properly. After the blood pressure was taken and analyzed, it was found that the subject’s blood pressure was 122/64 mm Hg and a pulse rate of 60 bpm. Now that the baseline was obtained, continuing with the changing variables could take place. Starting with the variable of postural changes, the subject first reclined for three minutes. After the two minutes, the

BMR = 655 + (4.35 x 159) + (4.7 x 67) – (4.7 x 31) = 1515.85 kcal/day

We decided to measure the subject’s pulse and respiratory rates whilst sitting down because there would be no additional stress on their heart, which would increase their heart rate. Their heart rate should also return to its resting heart rate due to the decrease of muscle use.
