  1. 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

cause of the respiratory acidpulmonary respiration. Metabolicosis is the

low not due to the pulmonary retof carbon dioxide but due to metabentionolic
disturbances. Some metabolic

Respiratory alkalosispH is high due to increase is that in which d expelling othef

  1. 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.)
