context_page_description: A ventricle is one of two large chambers toward the bottom of the heart that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs. The atrium primes the pump.
  In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta.
  The term "interventricular" means between the ventricles, while "intraventricular" means within one ventricle.
context_section_description: Ventricular pressure is a measure of blood pressure within the ventricles of the heart.
