Why do some people feel faint when they go quickly from lying to standing?!
Question: because your body is prone to this state of inactivity thus is in this resting stage. but once there is this dramatic force of movement then the body pumps blood fast thus the blood go quickly into your brain and other muscles.

Because the blood rushes from their head too quickly.
Low blood pressure.
Or anemia
its called vertigo, and it has to do with equilibrium, your inner ear, knocks you off balance
Because there is a liquid near your ears that swishes around and tells your body whether or not you are right side up, upside down, it pretty much gives you your sense of direction. If you get up too fast, this liquid swishes around, causing you to feel faint and dizzy. This is the same reason why you get dizzy when you spin around in circles.
EDIT: Ah, It's called the Equilibrium.
