Options

A. last cervical and 3rd thoracic vertebrae
B. last thoracic and 3rd lumbar vertebrae
C. last lumbar and 3rd sacral vertebrae
D. 3rd thoracic and last lumbar vertebrae

Answer

**Step-by-Step Solution:**

1. **Identify the Location of Kidneys**: The kidneys are bean-shaped organs located in the human body. They are typically described as dark red in color and are about 10 centimeters long and 5 centimeters wide.

2. **Understand the Position**: The kidneys are situated in the abdominal region of the body. More specifically, they are located towards the back side of the abdomen.

3. **Relate to the Vertebral Column**: The kidneys are positioned against the dorsal body wall, which means they are attached to the vertebrae of the spine.

4. **Determine the Specific Vertebral Levels**: The kidneys are located at the level of the 12th thoracic vertebra (T12) and extend down to the 3rd lumbar vertebra (L3). This means that the upper pole of the kidney is around the T12 level, and the lower pole is around the L3 level.

5. **Conclusion**: Therefore, in humans, the kidneys are located between the levels of the 12th thoracic vertebra and the 3rd lumbar vertebra.

**Final Answer**: The kidneys are located between the levels of the 12th thoracic vertebra (T12) and the 3rd lumbar vertebra (L3).
