Short Answer

Answer: c. right atrium

Step by step solution

Recall the basic structure of the heart

The human heart is divided into four chambers: right atrium, right ventricle, left atrium, and left ventricle.

Understand the flow of blood through the heart

Blood flows through the heart in the following sequence: 1. Deoxygenated blood from the body returns to the heart through veins and enters the right atrium. 2. Blood is then pumped from the right atrium into the right ventricle. 3. The right ventricle then pumps the blood to the lungs, where it picks up oxygen and releases carbon dioxide. 4. Oxygen-rich blood returns from the lungs to the heart, entering the left atrium. 5. Blood flows from the left atrium into the left ventricle. 6. The left ventricle pumps the oxygenated blood out to the rest of the body through arteries.

Determine the chamber that receives blood from the systemic circuit

Since deoxygenated blood coming from the systemic circuit (the body) first enters the heart in the right atrium, the correct answer is: c. right atrium
