respiratory system correct answers pH response system that has intermediate capacity and acts
within minutes
renal system correct answers pH response system that has high capacity, but takes hours to days
to take affect
buffer correct answers Acts to lessen the ability of acid or base to dramatically change pH
respiratory acidosis correct answers Accumulation of CO2 in the blood due to hypoventilation
impaired lung function (cystic fibrosis, emphysema), impaired ventilation (chest injury, weak
respiratory muscles), depression of respiratory center (brain stem injury) correct answers Causes
of respiratory acidosis
respiratory alkalosis correct answers Excessive elimination of CO2 due to hyperventilation
strong emotions (pain, fear, panic), abnormal respiratory control (brain tumor/injury) correct
answers Causes of hyperventilation
metabolic acidosis correct answers Excessive loss of bicarbonate, or excessive acid
severe diarrhea, renal disease, untreated diabetes mellitus, starvation, excess alcohol ingestion
correct answers Causes of metabolic acidosis
metabolic alkalosis correct answers Excessive loss of acid, excessive bicarbonate
vomiting, gastric suctioning, excessive ingestion of antacids, adrenal tumor (excessive
aldosterone) correct answers Causes of metabolic alkalosis
, increased sodium reabsorption (increased blood volume and pressure), increased potassium
secretion (maintain electrolyte balance), increased proton secretion (maintain acid-base balance)
correct answers Effects of aldosterone
acid-base compensation correct answers When one system causes pH imbalance, the other
system tries to compensate

cultural, psychological) as belonging to specific groups of people. "performance"
sex correct answers biological (XX or XY)
XX correct answers Sex chromosomes that will develop ovaries
XY correct answers Sex chromosomes that will develop testes
SRY correct answers Testis determining factor
