Verified step by step guidance1
Understand that the average adult human body contains a certain volume of blood, which is typically measured in liters or pints.
Recall that the average blood volume in an adult is approximately 5 liters, though this can vary based on factors like body size and sex.
Convert the average blood volume from liters to U.S. pints, knowing that 1 liter is approximately equal to 2.113 U.S. pints.
Multiply the average blood volume in liters by the conversion factor to find the volume in pints: \(\text{Blood volume (pints)} = \text{Blood volume (liters)} \times 2.113\).
Compare the calculated range to the given options to identify the correct approximate blood volume in pints for an average adult.
