HI

Blood is bright red when its hemoglobin is oxygenated.

The blood cells present in blood are mainly Red blood cells (also called RBCs or erythrocytes) and White Blood Cells including leukocytes and platelets.The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron- co containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood.
