Title: The Effects of Exercise on Respiratory Rate, Tidal Volume and CO2 Output.
Abstract:
The human body needs oxygen in order to function. Without enough of it, it is impossible to keep up with the energy demands that are required to keep the body alive. In order keep up with this demand, the respiratory centers in the brain will tell the body to breathe. If doing exercise, the demand for oxygen is higher, so more breathing must be done. Carbon dioxide is a waste product of metabolism when oxygen is used, so must be removed from the body. The body does this by exhaling breaths and just like oxygen needed for exercise, when more carbon dioxide is produced, then the brain will signal more breathing so the lungs can exhale the CO2 faster.

Introduction: Most life on earth requires oxygen in order to live. While they breathe in oxygen, carbon dioxide must be released as to not poison themselves. Carbon dioxide a waste product produced during cellular metabolism when oxygen is consumed when proteins, carbohydrates or fats are oxidized. The carbon dioxide is then transferred to the lungs for excretion by respiration. …show more content…
In the upper divisions, you have the nasal and oral cavities, the pharynx and the larynx. Air normally enters the part of the respiratory system called the nasal cavity through the nostrils (p.632). The air travels down into the pharynx, where the nose, mouth and throat connect. The lower divisions consist of the trachea, the left and right bronchus, lungs and the diaphragm. The lower division often is described as an inverted tree as the branches get smaller and smaller. It starts at the trachea and then proceeds to the right and left primary bronchus, the secondary bronchi, the tertiary bronchi, the smaller bronchi, bronchioles, respiratory bronchioles and finally the alveolar sacs which house the alveoli that are responsible for gas
