Fills with blue blood that enters through the superior vena cava and inferior vena cava
A
Right pulmonary veins
B
Right pulmonary artery
C
Right ventricle
D
Right atrium
Explanation: 

Detailed explanation-1: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.

Detailed explanation-2: -The inferior vena cava is ultimately responsible for the transport of almost all venous blood (deoxygenated) from the abdomen and lower extremities back to the right side of the heart for oxygenation.

Detailed explanation-3: -Transcript. Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve.

Detailed explanation-4: -The four chambers of the heart are attached to major veins or arteries that either bring blood into or carry blood away from the heart. The two largest veins in the body, the superior and inferior vena cava, bring the oxygen-poor (blue) blood to the heart into the right atrium.
