Verified step by step guidance

1. Understand that the problem is asking for the typical volume of blood in a healthy adult human body, which is a standard physiological fact rather than a calculation problem.
2. Recall that the average adult human body contains a certain volume of blood, which is often measured in liters or quarts. This volume depends on factors like body size and sex but generally falls within a known range.
3. Remember that 1 quart is approximately equal to 0.946 liters, and the average adult blood volume is about 4.5 to 5.5 liters.
4. Convert the average blood volume from liters to quarts by dividing the volume in liters by 0.946 to get the approximate number of quarts.
5. Compare the converted value to the given options to identify the correct range, which is typically about 5 to 6 quarts for a healthy adult.
