  • A Volume is 15-16 liters in an average sized adult male
  • B Slightly alkaline pH
  • C Constitute 20% of extracellular fluid
  • D Provide 8% of total body mass
Correct Answer

Explanation

The volume of blood in an average-sized adult male is not 15-16 liters. In fact, the total volume of blood in an adult male is around 5-6 liters, while in an adult female, it is around 4-5 liters. The pH of blood is slightly alkaline, with a range of 7.35-7.45. Blood constitutes around 20% of the extracellular fluid in the body and provides around 8% of the total body mass. These physical characteristics of blood are important to maintain the proper functioning of the body and to diagnose various disorders related to blood.
