Question

The function of red blood cells is to:
A)phagocytize bacteria.
B)transport oxygen and carbon dioxide.
C)transport nutrients to the body's cells and tissues.
D)stop blood loss from an injured blood vessel.

Accepted Answer

Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues and cells, and transporting carbon dioxide from the cells back to the lungs to be exhaled. They achieve this through the presence of hemoglobin, a protein that binds and carries oxygen and carbon dioxide. Red blood cells do not phagocytize bacteria or stop blood loss from an injured vessel, and while they do transport nutrients, this is not their primary function.
