Verified step by step guidance

1. Understand the function of the inferior vena cava: It is a large vein that carries deoxygenated blood from the lower half of the body to the heart.
2. Identify the pathway of blood flow in the heart: Blood from the inferior vena cava enters the right atrium of the heart.
3. Recognize the role of the right atrium: The right atrium receives deoxygenated blood from the body and passes it to the right ventricle.
4. Consider the options given: The left atrium, lungs, pulmonary artery, and superior vena cava are not directly connected to the inferior vena cava.
5. Conclude that the correct answer is the right atrium, as it is the chamber where blood from the inferior vena cava flows directly.
