Polarization by Use of a Polaroid Filter. The most common method of polarization involves the use of a Polaroid filter. Polaroid filters are made of a special material that is capable of blocking one of the two planes of vibration of an electromagnetic wave.
The lateral ventricles are part of the ventricular system of the brain. Both cerebral hemispheres contain a lateral ventricle. The lateral ventricles are the largest of the ventricles.
The left ventricle then pumps the oxygen-rich blood through the aorta and into all of the organs and tissues of the body. The right ventricle is located to the right of the left ventricle in the lower portion of the heart. This chamber pumps blood into the lungs through the pulmonary artery. There are four ventricles in the brain, including two lateral ventricles. These ventricles are fluid-filled spaces in the forebrain and brain stem. Cerebrospinal fluid circulates through the brain ventricles after being created in the ventricular system, specifically, the choroid plexus.
