The motor activity of the muscularis externa is controlled by the - myenteric plexus Which of the following are true regarding the secretion of HCl? (choose all that apply) a.) The H, K ATPase, also known as proten pump is present on the apical membrane of the parietnal cells. b.) As a by-product of the HCl secretion, HCO3- is transported out of the cell from the basolateral side of the cell. This can cause a alkaline tide (pH increase in plasma) immediately after a meal. c.) Na, K ATPases...
