Answer

To answer the question regarding the major veins that carry impure blood from various body parts to the heart, we can follow these steps:

### Step 1: Understand the concept of impure blood
Impure blood refers to deoxygenated blood, which is blood that has delivered oxygen to the body tissues and is now carrying carbon dioxide and other waste products back to the heart.

### Step 2: Identify the major veins involved
The two major veins responsible for carrying deoxygenated blood (impure blood) to the heart are:
1. **Superior Vena Cava**: This vein collects deoxygenated blood from the upper parts of the body, including the head, neck, arms, and upper torso.
2. **Inferior Vena Cava**: This vein collects deoxygenated blood from the lower parts of the body, including the abdomen and lower limbs.

### Step 3: Conclude the answer
Both the superior vena cava and the inferior vena cava are responsible for transporting impure blood back to the heart. Therefore, the answer to the question is:

**The major veins that carry impure blood from various body parts to the heart are the Superior Vena Cava and Inferior Vena Cava.**
