How many units of blood does an adult typically have?

6 units
8 units
12 units
15 units

The correct answer is: 12 units

An adult typically has about 12 units of blood in their body, which is roughly equivalent to 5 to 6 liters, depending on various factors including size and weight. Blood volume varies among individuals, but on average, adults are estimated to have this amount, making it critical for physiological functions, such as transporting oxygen and nutrients throughout the body. Understanding this helps in emergency situations where blood loss might be a concern, highlighting the importance of knowing average blood volumes for proper medical assessments and interventions.
