Am I correct in saying that when someone drinks a large amount of water, it **all** gets absorbed into the blood and then filtered out by the kidneys? as opposed to having a direct passage from the GI tract to the bladder? (sorry may be a stupid question)

Pretty much. There is NO normal direct connection between the gut and the urinary bladder in the human adult. So when you drink water, most of it will be absorbed through the gut into the blood, and then be distributed throughout the body (not all of it just gets filtered back out right away; we lose water continually and need to replace it). Some stays in the gut and is excreted in your poop (which is not perfectly dry).
