Detailed explanation-1: -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-2: -Also called RBC and red blood cell.
Detailed explanation-3: -Red blood cells squeeze through narrow capillaries in single file. Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body.
Detailed explanation-4: -The biconcave shape allows RBCs to bend and flow smoothly through the body’s capillaries. It also facilitates oxygen transport. Red blood cells are considered cells, but they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria.
