The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Respiration in Tissues:** - In the tissues, cellular respiration occurs, which is the process by which cells produce energy. During this process, oxygen is consumed, and carbon dioxide (CO2) is produced as a waste product. 2. **Accumulation of Carbon Dioxide:** - As cells respire, they release carbon dioxide into the surrounding tissue fluid. This leads to an accumulation of CO2 in the tissues. 3. **Blood Flow from Tissues:** - Blood flows through the tissues, picking up the waste products, including carbon dioxide. 4. **Binding of Carbon Dioxide to Hemoglobin:** - The blood contains hemoglobin, a protein that has a high affinity for carbon dioxide. When blood passes through the tissues, it binds to the excess CO2 present there. 5. **Conclusion:** - Therefore, the blood that leaves the tissues becomes richer in carbon dioxide due to the accumulation of CO2 from cellular respiration and its binding to hemoglobin. **Final Answer:** The blood leaving the tissues becomes richer in carbon dioxide. ---
