In the context of tissue structure, what is the primary function of a red blood cell (erythrocyte)?
A
Generate nerve impulses for rapid communication between tissues
B
Synthesize and secrete extracellular matrix proteins such as collagen
C
Transport oxygen (and some carbon dioxide) through the bloodstream via hemoglobin
D
Produce antibodies to provide adaptive immune protection
Verified step by step guidance1
Identify the main role of red blood cells (erythrocytes) in tissue structure by recalling their biological function.
Recall that red blood cells contain hemoglobin, a protein specialized in binding oxygen molecules.
Understand that red blood cells transport oxygen from the lungs to various tissues and carry some carbon dioxide back to the lungs for exhalation.
Recognize that red blood cells do not generate nerve impulses, synthesize extracellular matrix proteins, or produce antibodies, as these functions belong to other cell types.
Conclude that the primary function of red blood cells is to transport oxygen (and some carbon dioxide) through the bloodstream via hemoglobin.
