The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the type of cells that line the blood capillaries. 2. **Identifying the Structure**: Blood capillaries are tiny blood vessels that facilitate the exchange of oxygen, nutrients, and waste products between blood and tissues. 3. **Recognizing the Cell Type**: The cells that form the inner lining of blood capillaries are specialized cells known for their role in this exchange process. 4. **Naming the Cells**: These specialized cells are called **endothelial cells**. They form a thin layer that is crucial for maintaining the barrier between the blood and the surrounding tissues. 5. **Excluding Other Options**: - **Auxentis cells** (also known as parietal cells) are found in the stomach and are responsible for secreting hydrochloric acid and intrinsic factor. - **Hemocytes** refer to blood cells, particularly in invertebrates, and in this context, they are not relevant as they do not line capillaries. 6. **Final Answer**: Therefore, the cells lining the blood capillaries are called **endothelial cells**. ---
