Chapter 16, Problem 1MC
The blood volume in an adult averages approximately (a) 1 L, (b) 3 L, (c) 5 L, (d) 7 L.
Expert Solution & Answer
Summary Introduction
To determine:
The average blood volume in an adult is approximately:
1L
3L
5L
7L
Answer to Problem 1MC
Correct answer:
(c) 5 L
Explanation for the correct answer:
Option (c) is given as 5L. The blood volume is the total volume of the blood present in the circulatory system of the human body. Blood volume is the volume of blood (both red blood cells and plasma) in the circulatory system of any individual. A typical adult weighing between 150 to 160 pounds has 5 L (liters) of blood in the body. It is seen that females usually have low blood volume as compared to the males. Hence, option (c) is the correct answer.
Explanation of Solution
Explanation for the incorrect answers:
Option (a) is given as 1L. The average blood volume in an adult is approximately 5L not 1L. Nearly, 30 to 40% loss of blood causes death in humans. Hence, option (a) is the incorrect answer.
Option (b) is given as 3L. The average blood volume in an adult is approximately 5L not 3L. Nearly, 30 to 40% loss of blood causes death in humans. Hence, option (a) is the incorrect answer.
Option (d) is given as 7L. The average blood volume in an adult is approximately 5L not 7L. Blood volume increases with obesity, although to a lesser extent than body weight and volume. Hence, option (d) is the incorrect answer.
Conclusion
The average blood volume in an adult is approximately 5L.
