**Question 1**

**Which structure of the heart contains deoxygenated blood?**

**Options:**

A. Left atrium

B. Right atrium

C. Left ventricle

D. Aorta

**Correct Answer:**

B. Right atrium

**Rationale:**

The right atrium receives **deoxygenated blood** from the body via the superior and inferior
vena cava. The left side of the heart carries oxygenated blood, making options A and C incorrect.
The aorta (D) carries oxygenated blood away from the heart.
