"drawing a compression"? You'll have to fill me in on what that means.

Hollows do not need to drink, only eat other spirits to fuel their raging hunger and become stronger. Knowing there's blood in someone's body is different from knowing there's water in someone's body. Hallibel can't move blood. Also, since there is a lack of water in Hueco Mundo, Tier would probably have to use the water she creates on her own.

What we know as common knowledge might not be the same for Hollows. Barragan didn't know there were any realms besides Hueco Mundo until Aizen told him. They're in a massive desert, always on the run from other, stronger, hollows. The only seeming form of government was Barragan's kingdom, and he didn't do anything but eat and force his subjects to hunt and do battle for his amusement. Knowledge doesn't seem like a very useful thing compared to strength when you're in a constant flight-or-fight situation.
