Probable Cause. The Fourth Amendment provides that no warrants shall issue, but upon probable cause.. The Constitution doesn't furnish any definition of probable cause, leaving that task to the Supreme Court, which has also applied the probable cause standard to certain warrantless activities.
Exercise increases the rate and depth of breathing. The heart rate increases during exercise. The rate and depth of breathing increases-this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.The rate of breathing can be measured by counting the number of breaths in one minute.xercise increases the rate and depth of breathing. The heart rate increases during exercise. The rate and depth of breathing increases-this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
Build-up of CO2 therefore causes an equivalent build-up of the disassociated hydrogen ions, which, by definition, decreases the pH of the blood. The pH sensors on the brain stem immediately sense to this fall in pH, causing the respiratory center to increase the rate and depth of breathing. The consequence is that the P C O 2 {\displaystyle P_{{\mathrm {CO} }_{2}}} (partial pressure of carbon dioxide) does not change from rest going into exercise.
