Question

Which blood cells are responsible for carrying oxygen throughout the body?

• A. White blood cells
• B. Platelets
• C. Red blood cells
• D. Plasma cells

Hint:

{Red Blood Cells (RBCs) contain hemoglobin}, which carries oxygen throughout the body.

Answer 1

The Correct Option is C

Concept: Red blood cells (RBCs), also called erythrocytes, are responsible for transporting oxygen from the lungs to the tissues throughout the body. RBCs contain a protein called hemoglobin, which binds with oxygen molecules and carries them through the bloodstream.
Step 1: Understand the oxygen transport mechanism.
Hemoglobin in red blood cells combines with oxygen in the lungs and delivers it to body tissues where it is required for cellular respiration.
Step 2: Eliminate other options.

• White blood cells help fight infections.
• Platelets are involved in blood clotting.
• Plasma is the liquid component of blood.

Thus, the blood cells responsible for transporting oxygen are red blood cells.
