In an adult, what is approximately the total blood volume in cc?

The total blood volume in an adult is generally approximated to be around 5000 cc (or 5 liters). This value can vary based on factors such as body size, weight, and overall health, but 5000 cc is a commonly accepted average for a typical adult.

Blood volume is essential for maintaining circulation, transporting oxygen and nutrients, and supporting various bodily functions. The distribution and volume of blood are critical aspects of both physiological and medical studies, as they relate to conditions like blood loss, dehydration, and overall cardiovascular health.

Other choices reflect values that are less representative of the standard range for adult blood volume. While it is possible for individuals to have higher or lower volumes based on specific conditions or body compositions, 5000 cc is widely recognized as the norm.
