The reduction of the respiratory

- What is the difference
between respiratory acidosis
and metabolic acidosis and
what is the difference
between respiratory alkalosis
and metabolic alkalosis?
Respiratory acidblood pH is low dosis is that in ue to increasedwhich th e
retention of carbon dioxide caused by
the lowering of the respiratoryfrequency or by pulmonary diseas (^) es
that impair the gas exchange. So the
cause of the respiratory acidpulmonary respiration. Metabolicosis is the
acidosis is that in which the blood pH is
low not due to the pulmonary retof carbon dioxide but due to metabentionolic
disturbances. Some metabolic
disturbances rblood of nonvolatile acids that relesult in liberation in theease (^)
hydrogen ions lowering the blood pH
(e.g., diabetic ketoacidosis).
Respiratory alkalosispH is high due to increase is that in which d expelling othef
carbon dioxide caused by elevated
respiratory fralkalosis is the alkalosisequency. Metabolic caused by (^)

- Where are the
chemoreceptors that detect
the acidity of the blood and
trigger the respiratory
compensation located?
The chemoreceptors that participate inthe ventilation control are structures
that collect information about the acidity
and alkalinityinformation is then transmitted by of the blood. The (^)
nervous fibers to the respiratory center
located within ththen commands the medulla. The centere respiratory muscles (^)
to compensate the abnormal pH.
There are central and peripheralchemoreceptors. Peripheral
chemoreceptors opartial pressure and oxygen partialf pH, carbon dioxide
pressure are located iaorta and of the carotid n the wallsarteries. C of theentral (^)
chemoreceptors that get pH information
are located respiratory cewithin thnter. (The pulmonarye medulla in the
ventilation is also controlled by
receptors tfrom the cerebrospinal flhat receive pH informationuid.)
