Which of the following is not a function of gastric hydrochloric acid (HCI)?

A. Glomerular capillaries are involved in the filtration of blood to form the glomerular filtrate, not in the reabsorption of glucose and amino acids.

B. Proximal convoluted tubule is where the majority of glucose and amino acids are reabsorbed from the glomerular filtrate back into the bloodstream.

C. Renal corpuscle consists of the glomerulus and Bowman's capsule and is involved in the filtration process, not in reabsorption.

D. Distal convoluted tubule is involved in the fine-tuning of electrolyte and acid-base balance, not in the primary reabsorption of glucose and amino acids.

A. The bicarbonate, phosphate, and protein: The major chemical buffer systems in the body are the bicarbonate buffer system, the phosphate buffer system, and the protein buffer system. These buffers help maintain pH balance in the blood and other fluids.

B. The urinary and digestive: The urinary and digestive systems are involved in excretion and digestion, not buffering.

C. The bicarbonate, nucleic acids, and protein: Nucleic acids are not major buffering systems in the body; the bicarbonate, phosphate, and protein systems are the primary ones.

D. The urinary and respiratory systems play roles in regulating acid-base balance through excretion and gas exchange but are not chemical buffer systems themselves.
