fill the blanks with the terms given
Terms: acidotic, deeply, drop, excessive, hyperventilating, hypoventilating, insufficient, partial pressure, rise, shallowly
When an individual increases tissue activity [i.e. increases skeletal muscle activity during exercise], the working tissues need more oxygen to fuel their energy-requiring processes and they generate more waste carbon dioxide gas per unit time. Under these conditions, the respiratory system will adjust the breathing pattern such that the individual breaths faster and/or deeper, to get the needed oxygen into and carbon dioxide out of the body such that the content of these gasses in the blood remains at normal [acceptable, or within 'set-point'] levels. However, occasionally breathing pattern [i.e. ventilation] is not properly matched to respiratory need and one ends up over- or under-breathing. When one is over-breathing s/he is _____________; that is, s/he is breathing too rapidly and/or too ____ for what is needed to eliminate the CO2 being generated at the time. This 'over-breathing' ends up causing __________ amounts of CO2 to be eliminated from the body per unit time, which ultimately leads to a ________ in the ______________ of CO2 (a.k.a. PCO2)in the blood. Conversely, when one is under-breathing, s/he is ____________ - or breathing too slowly and/or too ____________ for what is needed to eliminate the CO2 being generated in the body tissues at the time. This 'under-breathing' ends up causing __________ amounts of CO2 to be eliminated from the body per unit time, which ultimately leads to a ________ in the partial pressure of CO2 in the blood. Accumulation of increased CO2 in blood can cause the body fluids to become _________ because the CO2 will react as follows: CO2 + H2O H2CO3 H+ + HCO3-.
