Answer 4

• emulsification of fats
• detoxification of alcohol
• a rise in blood glucose levels between meals

Answer 5

Yep you are right @happy_go_swimmer
• emulsification of fats - Liver (by producing bile that in turn emulsifies fats)
• secretion of peptidases - its site depends on what kind of peptides are to be secreted
• capillary fluid exchange - as it already says it happens in capillaries
• detoxification of alcohol - Liver (some types of peroxisome in liver cells do this detoxification)
• neutralization of pancreatic juice - happens in stomach, pancreatic juice is highly alkaline due to high levels of sodium bicarbonates in it which is why it can neutralize acidic gastric juice. In other words it- itself gets neutralized by the acid as well (i think thats what they are referring to)
• a rise in blood glucose levels between meals - Liver is a major site of glucose storage in the form of glycogen so when the need for glucose arises - Liver cells are stimulated to break down glycogen to glucose & release it to blood stream

Answer 6

@Somy: neutralization by pancreatic juice (of gastric juice) occurs in the duodenum, not stomach.

Answer 7

@shiraz14 yeah true hehe my bad :3 i was thinking of the other neutralization that is in stomach, so yep, my bad there :D
