Verified archiveThe correct answer is C. They transport oxygen throughout the body.
Red blood cells (RBCs), also known as erythrocytes, play a crucial role in the human body by carrying oxygen from the lungs to the tissues and organs. They contain hemoglobin, a protein that binds to oxygen, allowing for efficient oxygen delivery. This function is vital for energy production and overall cellular metabolism.
