Which fingerlike projections found in the dural venous sinuses reabsorb cerebrospinal fluid? a. arachnoid villi b. choroid plexuses c. dural villi d. lemnisci e. microvilli?

The most correct answer for the above question is the Arachnoid villi. They are tufts of arachnoid membrane invaginated into the dural sinuses through which cerebrospinal fluid enters the venous system. They act as one way valves and they normally penetrate the overlying dura and invaginate through the walls of the superior sagittal sinuses and other venous structures. 

Let’s think about this, we can already cross out D because that is the small intestine’s function, that isn’t a picture of the small intestine.

We can also cross out A for the answers because the gallbladder is the organ that creates bile and that once again isn’t the picture of that organ.

That leaves C and B.

The stomach produces pepsin and makes hydrochloric acid, this isn’t a picture of the stomach, so that leaves you with C.

The answer to your question is C, since this is a picture of the pancreas, and the pancreas’ job is to produce enzymes that breaks down carbohydrates.
