Describe the blood flow path in the heart starting from the right side
What is Blood enters the right atria from the superior and inferior vena cava tricuspid valve opens for passive filling from right atria to right ventricle. atrias Contract filling the rest of the ventricle using the atrial kick. tricuspid valve closes. right ventricle contracts sending blood through the pulmonary artery to the lungs passing through the pulmonary semilunar valve. Blood returns from lungs through the pulmonary vein to the left atria. left atria passively fills the left ventricle through the bicuspid (mitral) valve. left atria finishes filling the left ventricle when atria contracts using the atrial kick. bicuspid valve closes left ventricle contracts sending blood through the aortic semilunar valve to the body
