However, those close to the heart have the thickest walls, containing a high percentage of elastic fibers in all three of their tunics. WitrynaThe atria receive venous blood on a nearly continuous basis, preventing venous flow from stopping while the ventricles are contracting. While most ventricular filling occurs while the atria are relaxed, they do demonstrate a contractile phase and actively pump blood into the ventricles just prior to ventricular contraction.

WitrynaBoth the atria and ventricles are relaxed and the blood enters at low pressure through the veins, the pulmonary vein and the vena cava into the atria.
