Understand that the average adult human body contains about 5 liters of blood. This is a commonly accepted physiological estimate.
Recall the conversion factor between liters and ounces: 1 liter is approximately equal to 33.814 ounces.
Set up the conversion calculation using the formula: \(\text{Total ounces} = \text{Volume in liters} \times 33.814\).
Multiply the average blood volume (5 liters) by the conversion factor (33.814 oz/L) to find the total blood volume in ounces.
Compare the calculated value to the given options to select the closest approximate amount of blood in ounces.
