Which of the following blood components has the greatest affinity for oxygen and carbondioxide?
Answer Details
Erythrocytes, also known as red blood cells, have the greatest affinity for oxygen and carbon dioxide. This is because they contain a protein called hemoglobin, which binds to oxygen and carbon dioxide and transports them throughout the body. Hemoglobin has a high affinity for oxygen, which allows it to pick up oxygen in the lungs and deliver it to tissues throughout the body that need it. Hemoglobin also has a moderate affinity for carbon dioxide, which allows it to pick up carbon dioxide from tissues and transport it back to the lungs to be exhaled. Therefore, erythrocytes are essential for maintaining proper oxygen and carbon dioxide levels in the body.
