Average human body has how many liters of blood?

• A. 3-4
• B. 4-5
• C. 5-6
• D. 6-7

Answer: (C)

Blood volume in a healthy adult is about 7-8% of body weight, roughly 5 to 6 liters. For a typical 70 kg person, that’s around 5 liters, and it can climb toward 6 liters in larger individuals. Since the question asks for the average value, the range of five to six liters best represents a typical adult. Lower ranges like 3-4 or 4-5 liters are below average for most adults, while 6-7 liters is above the common average. This amount supports essential circulation, oxygen transport, and overall circulatory function in an average adult.
