Answer to Question 1

C
The heart has four chambers: two atria and two ventricles. The right and left sides of the heart are separated by an internal wall of connective tissue called a septum. The interatrial septum separates the right and left atria. The interventricular septum separates the right and left ventricles. The septa separate the heart into two functional pumps. The right atrium and right ventricle make up one pump. The left atrium and left ventricle make up the other.

Answer to Question 2

D
The right atrium receives blood low in oxygen from the superior vena cava, which carries blood from the head and upper extremities; the inferior vena cava, which carries blood from the lower body; and the coronary sinus, which is the largest vein that drains the heart.
