Name four secretions/enzymes produced in the stomach. | Pepsinogen, HCL acid, Lipase, Intrinsic factor |
What is the function of pepsinogen? | protein digestion |
What is the function of HCL acid? | Activation of pepsinogen to pepsin |
What is the function of Lipase? | Fat digestion |
What stomach secretion is essential for the absorption of cobalamin in the ileum? | Intrinsic factor |
About how much juice is produced by the stomach in a day? | 2,500mLs |
