The superior mineral vein cava and the inferior vena cava. When the right auricle contracts, it forces the blood through an opening into the right ventricle. condensing of this ventricle drives the blood to the lungs. Blood is prevented from returning into the auricle by the tricuspid valve, which completely closes during compression of the ventricle. In its overtaking through the lungs, the blood is oxygenated, that is, then it is brought back to the heart by the four pulmonary veins, which enter the left auricle. When this chamber contracts, blood is strained into the left ventricle and then by ventricular contraction into the aorta. The bicuspid, or mitral, valve prevents the blood from flowing back into the auricle, and the semilunar valves at the beginning of the aorta stop it from flowing back into the ventricle. resembling valves be present in...
