What is the normal adult blood volume?

Explanation:
Normal adult blood volume is about five liters. This amount represents roughly 7–8% of body weight, so for a typical 70 kg person it's around 4.9 liters. In practice, five liters is used as the standard estimate because body size causes only modest variation: about 4.5–5.5 liters can be expected across adults. This standard value is important in clinical settings to gauge blood loss, transfusion needs, and fluid management.
