A: Enlarged ventricles in the brain may be a sign of normal pressure hydrocephalus. It happens when one or more ventricals, which are normally hollow areas in the brain, have too much cerebrospinal fluid. Cerebrospinal fluid, or CSF, is made and stored in the brain's ventricles.
The contraction of the ventricular muscle raises the pressure in the ventricle. The high pressure in the ventricle forces the bicuspid valve to close and forces blood up the aorta. The diagram shows that the semi-lunar valves are pushed open. During diastole the thick muscular walls of the ventricles relax. The pressure of the blood in the ventricles falls low enough for the bicuspid valve to open. At the same time, the atrium contracts. Blood is forced from the atrium into the ventricle. This blows the ventricle up like a balloon. Source(s): .
