Human Respiration

Normal values range from 12 to 20 breaths per minute.
The Inspiratory Reserve Volume (IRV) is the quantity of air that is taken into the lungs during a maximal forced inspiration that begins at the end of a normal inspiration. The trace for vital capacity shows an IRV reading of 2300cc. The normal value for IRV is 2500cc.
The Expiratory Reserve Volume (ERV) is the quantity of air that is expelled from the lungs during a maximal forced expiration that begins at the end of a normal expiration. The trace for vital capacity shows a reading of 900cc for ERV. The normal value of ERV is 1500cc.
The Vital Capacity (VC) is the total volume of air that is expelled from the lungs during a forced maximal exhalation that occurs after a forced maximal inhalation. The trace for vital capacity shows a direct VC reading of 4100cc. The normal value for VC is 4800cc.
The depth of breathing at the start of the experiment is shown in the trace for CO2 accumulation part A. The TV reading is 1000cc. The depth of breathing at the end of the experiment is shown in the trace for CO2 accumulation part B. The TV reading is 1500cc.
The frequency of breathing at the beginning of the experiment is shown in the trace for CO2 accumulation part A. The frequency at the beginning is 10 breaths per minute. The frequency of breathing at the end of the experiment is shown is the trace for CO2 accumulation part B. ...

Frequency of Breathing at the Start and End of the Experiment
The frequency of breathing at the beginning of the experiment is shown in the trace for CO2 accumulation part A. The frequency at the beginning is 10 breaths per minute. The frequency of breathing at the end of the experiment is shown is the trace for CO2 accumulation part B. The frequency at the end of the experiment is 17 breaths per minute.

Sensations of Subject at the End of the Experiment
Subject reports a slight feeling of breathlessness at the end of the experiment and reports the sensation of shallowness of normal breathing.
EFFECT OF REBREATHING WITH CARBON DIOXIDE ABSORPTION
The two traces that show the effects of rebreathing with carbon dioxide absorption are shown in the diagrams labelled CO2 Absorption Part A and CO2 Absorption Part B.

Depth of Breathing at the Start and End of the Experiment
The depth of breathing at the start of the experiment is shown in the trace for CO2 absorption part A. The TV reading is 1000cc. The depth of breathing at the end of the experiment is shown in the trace for CO2 absorption part B. The TV reading ranges from 1200cc to 1500cc.
Frequency of Breathing at the Start and End of the Experiment
The frequency of breathing at the beginning of the experiment is shown in the trace for CO2 absorption part A. The frequency at the beginning is 12 breaths per minute. The frequency of breathing at the end of the experiment is shown is the trace for CO2 absorption part B. The frequency at the ...Show more

Summary

The Tidal Volume (TV) is the quantity of air that a person is breathing in and out under a normal resting respiratory cycle. The trace for normal breathing shows a reading varying between 3000cc of air and 4000cc. This shows a value for TV of 1000cc. Normal values for TV are 500cc.

Aerobic Cellular Respiration in Isolated Mitochondria of Lima Bean Seeds
A basic concept in cellular respiration is the transfer of chemical energy (electrons) from an electron donor to an electron acceptor. Most of the organisms use oxygen as the final electron acceptor although some organisms (eg. Yeast) use other alternatives.

Cellular respiration and fermentation

From this research, it is clear that respiration processes and fermentation processes are similar in that both have carbon dioxide involved in the processes. In the respiration process, the carbon dioxide is the respired gas. In the fermentation process involving glucose carbon dioxide is the byproduct of the reaction that mainly results in the conversion of glucose into ethanol.

Respiratory Function
This is done when we breathe. We inhale oxygen (O2) and exhale carbon dioxide (CO2). In this manner air is distributed to many parts of the human body. The Respiratory system also comprises the olfactory receptors involve for the sense of smell. "The respiratory system helps regulate the balance of acid and base in tissues, a process crucial for the normal functioning of cells.
