Final answer:
The atria, including both the left atrium and right atrium, are responsible for receiving blood and driving it into the ventricles, which then pump blood away from the heart.
Step-by-step explanation:
The structure of the human heart that receives blood and drives it into the ventricle for pumping blood away from the heart is known as the atrium. Specifically, for the choices provided, the correct options are A) Left Atrium and B) Right Atrium since both atria perform the function of receiving blood and transferring it to the respective ventricles (the left ventricle and right ventricle). It is important to note that the ventricles, such as the right ventricle mentioned in the student's choices, serve as the primary pumping chambers that propel blood to either the lungs or the rest of the body.
