why two pulmonary veins enter the heart?

Answers

Answered by Anonymous

The right and left sides of the heart work together. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
