**Educational Text:**

Consider oxyhemoglobin in hard-working tissues. Using the graph below, what is the percentage of oxyhemoglobin when the PO2 is 40 mmHg?

**Graph Explanation:**

The graph is a dissociation curve showing the relationship between the partial pressure of oxygen (PO2) in mmHg (x-axis) and the percentage of oxyhemoglobin (y-axis).

- **X-axis:** PO2 values ranging from 0 to 100 mmHg.
- **Y-axis:** Oxyhemoglobin percentage ranging from 0% to 100%.
- **Curve:** The main curve (in bold) illustrates how the saturation of hemoglobin with oxygen changes with varying PO2. The curve has a characteristic sigmoid shape, indicating cooperative binding of oxygen to hemoglobin.

At a PO2 of 40 mmHg, the curve suggests that the percentage of oxyhemoglobin is approximately 75%. This implies that under these conditions, hemoglobin is 75% saturated with oxygen in hard-working tissues.
