Which component of blood is responsible for oxygen transport?

The component of blood responsible for oxygen transport is red blood cells, also known as erythrocytes. These cells contain a protein called hemoglobin, which binds to oxygen in the lungs and carries it through the bloodstream to tissues and organs throughout the body. This process is crucial for maintaining the body's overall function since oxygen is essential for cellular metabolism and energy production.

Platelets play a key role in blood clotting and wound healing, while white blood cells are primarily involved in the immune response, helping the body fight infections and diseases. Plasma, the liquid component of blood, serves as a medium for transporting nutrients, hormones, and waste products but does not have a direct role in oxygen transport. Therefore, red blood cells are specifically adapted for this vital task, making them the correct answer.
