Respiration must deliver oxygen to our cells and take carbon dioxide, the waste product, to the lungs to be exhaled. Dalton's law of partial pressures helps to explain the way in which this process occurs. Why is a low concentration of CO 2 in our blood good while a high concentration is bad
Homework Answers
High concentrations of CO2 can lead to the formation of an acidic environment which can further result in many other problems in the body such as headache, sleepiness, fatigue, lack of appetite, confusion, rapid or slow breathing.

A. . Hyperpnea would result in ___________________________ within the blood. an increase in both Pressure (oxygen) and Pressure (carbon dioxide) 2. Decreased Pressure (carbon dioxide) results in an increase in blood pH levels. Both of these conditions result in a shift of the oxygen-hemoglobin dissociation curve to the ______________________. This shift _______________ hemoglobin’s affinity for oxygen. select 3. Increased levels of 2,3 BPG occur in response to decreased blood pH levels.
