Verified step by step guidance

1. Understand that the question asks for the approximate volume of blood in a typical healthy adult human body, measured in quarts.
2. Recall that the average adult human body contains about 4.5 to 5.5 liters of blood, which is a commonly accepted physiological range.
3. Convert liters to quarts, knowing that 1 liter is approximately equal to 1.057 quarts. Use the conversion formula: \(\text{quarts} = \text{liters} \times 1.057\).
4. Apply the conversion to the average blood volume (around 5 liters) to estimate the volume in quarts.
5. Compare the calculated value to the given options and select the one closest to the estimated volume.
