The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the state of blood in veins and arteries after human death. 2. **Post-Mortem Changes**: After death, the body undergoes several changes, one of which is rigor mortis. This is a process that leads to stiffness in the muscles and can affect blood circulation. 3. **Blood Distribution After Death**: - When a person dies, the heart stops pumping blood. - Due to the cessation of circulation, blood begins to settle in the lower parts of the body due to gravity. 4. **Condition of Veins and Arteries**: - **Veins**: After death, veins tend to become dilated and can retain blood because they are more compliant and can hold more volume. - **Arteries**: In contrast, arteries are muscular and tend to constrict, leading to a decrease in the volume of blood they contain. They may also be emptied due to the lack of pressure from the heart. 5. **Conclusion**: Based on these observations, after death, veins are typically full of blood while arteries are empty. Therefore, the correct answer is that veins are full of blood and arteries are empty. ### Final Answer: Veins are full of blood while arteries are empty after death. ---
