Question
Which of the following is NOT true of erythrocytes?They transport oxygen from the body back to the lungs.They make up 45% of your total blood volume.They pick up carbon dioxide from the cells/tissues.They carry both oxygen and carbon dioxide at various times.
Solution
The statement that is NOT true of erythrocytes (red blood cells) is: "They transport oxygen from the body back to the lungs."
Erythrocytes are responsible for carrying oxygen from the lungs to the body's tissues and cells, not the other way around. They do pick up carbon dioxide from the cells/tissues and transport it back to the lungs, where it is exhaled. Erythrocytes make up about 45% of the total blood volume and they do carry both oxygen and carbon dioxide at various times, but the direction of oxygen transport mentioned in the first statement is incorrect.
