Summary Introduction
Introduction: The process of circulation inside the body of an organism is responsible for the transportation of oxygen and various nutrients. The purpose of circulation is to fulfill the demands of the tissues and organs and to maintain the internal environment of the body. Blood is the responsible for transportation of various types of

Which of the following is NOT a way that carbon dioxide exits the body? *
A. carbon dioxide travels down the concentration gradient and is able to diffuse from the tissues directly out of the body through its pores.
B. carbon dioxide dissolves directly into the blood plasma to be carried to the lungs where it will be exhaled.
C. Carbon dioxide binds with hemoglobin as red blood cell pass through tissues and is released as the blood cells reached the lungs.
D. carbon dioxide converts into bicarbonate ions in the blood as it diffuses from the tissues and converts back to carbon dioxide as it reaches the lungs to be exhaled
