Textbook Question
The blood volume in an adult averages approximately:
a. 1 L
b. 3 L
c. 5 L
d. 7 L.
Verified step by step guidance1
Understand that blood volume refers to the total amount of blood circulating within an adult human's cardiovascular system.
Recall that the average blood volume in adults is typically measured in liters and varies based on factors such as body size and sex.
Recognize that the average blood volume for an adult is generally around 7-8% of their total body weight.
Use the average adult body weight (approximately 70 kg) to estimate blood volume by calculating 7-8% of this weight, which gives a value close to 5 liters.
Compare the calculated estimate with the given options to identify the closest value representing average adult blood volume.
