Answer Details
The blood component that has the greatest affinity for oxygen is the erythrocytes, also known as red blood cells. These cells contain a protein called hemoglobin which binds to oxygen molecules in the lungs and carries them to tissues throughout the body. Hemoglobin is a highly specialized molecule that can bind up to four oxygen molecules at a time, and it is the primary means by which oxygen is transported in the bloodstream. Therefore, erythrocytes play a vital role in delivering oxygen to the body's tissues and organs.
