thylakoids
Chloroplasts contain saclike photosynthetic membranes called thylakoids, which are interconnected and arranged in stacks known as grana. Pigments are located in the thylakoid membranes. The fluid portion outside of the thylakoids is known as the stroma.

The immune system, and the excretory system
(Honestly, all of them work to keep us 'healthy', but I believe these are the ones you're looking for)
When someone is lactose intolerant, it means its intestine cannot absorb lactose, which will stay in the lumen and be consumed by intestinal bacteria and produced gases, that's why intolerant lactose people have flatulence and abdominal pain while eating food with lactose in it.
Let's go back to the question, before being consumed, lactose in the lumen intestine will attract water from the enterocytes to its side by oncotic pressure.
Do not confound oncotic pressure (which concerns macromolecules like sugar or proteins) and osmotic pressure (which concern micromolecules like small ions (sodium potassium and chloride...)).
