- Harry ate a late meal at a cheap diner on the way home from work.A couple of hours later, he vomited three times, and then he consumed several packages of an antacid (mostly NaHCO3) over thenext several hours. By the evening of the next day, he was feelingbetter. During this ordeal, his blood pH did not deviate significantly.Select the mechanism(s) that helped maintain Harry’s pH within anormal range.(1) increased respiratory rate(2) increased H+ secretion by the renal tubule(3) decreased respiratory rate(4) decreased H+ secretion by the renal tubulea. 1 b. 2 c. 1,2 d. 3 e. 3,4arrow_forwardIf the Tm for a particular amino acid is 220 mg/100 ml and the concentration of that amino acid in the blood is 130 mg/100 ml, the amino acid will Question options: a) not appear in the urine because it is too large to be filtered b) be actively secreted into the filtrate d) be completely reabsorbed by the tubule cells 回Focus English (United States)arrow_forwardThe kidneys are stimulated to produce renin Question options: a) when the sympathetic nervous system is activated b) by an increase in the blood pressure when the pH of the urine decreases e)arrow_forward
