QUESTION:

Problem 8PE

The human circulation system has approximately 1×109 capillary vessels. Each vessel has a diameter of about 8 µm . Assuming cardiac output is 5 L/min, determine the average velocity of blood flow through each capillary vessel.

ANSWER:

Step 1 of 4:

The human blood circulation system allows blood to carry nutrients, oxygen and etc. The blood flows from heart to other organs. This system has capillary vessels. The diameter of the single vessel is given. We are going to find the average velocity of blood flow through each vessel.

The number of capillary vessels

The diameter of each vessel

The radius of the vessel  or

The volume flow rate of the blood
