Question
Chapter 14, Problem 6RA
Summary Introduction
To determine:
The blood vessel posing highest resistance to the blood flow.
Introduction:
Blood is the major transportation agent in human body. It helps to transport hemoglobin, electrolyte, protein and even hormones. Blood is rich in hemoglobin and RBC (red blood cells) with WBC (white blood cells). The blood also serves as the carrier for transporting the respiratory gases namely oxygen and carbon dioxide.
