Detailed explanation-1: -RBCs or Red Blood Corpuscles are cells in mammals that do not contain a nucleus . This primarily is because it enables the RBC to carry oxygen more efficiently.
Detailed explanation-2: -Erythrocytes (red blood cells or RBCs) are anucleate, biconcave cells, filled with hemoglobin, that transport oxygen and carbon dioxide between the lungs and tissues. They are produced in the red bone marrow by a process called erythropoiesis.
Detailed explanation-3: -Almost all vertebrate organisms have hemoglobin-containing cells in their blood, and with the exception of mammals, all of these red blood cells are nucleated.
Detailed explanation-4: -The term anucleate means lacking a nucleus. Mature red blood cells (erythrocytes) are anucleate.
Detailed explanation-5: -Anucleated red blood cells metabolize anaerobically (without oxygen), making use of a primitive metabolic pathway to produce ATP and increase the efficiency of oxygen transport.
