Human red blood cells

Red blood cells, also referred to as erythrocytes, are the most common type of blood cell and the bodies principal means of delivering oxygen to the tissues via blood flow through the circulatory system. RBCs take up oxygen in the lungs and release it as they pass through the body’s capillaries. Red blood cells in the cytoplasm are rich in haemoglobin, an iron-containing molecule that binds oxygen and is responsible for the red colour found in blood.

In humans, mature red blood cells are oval shaped disks lacking a cell nucleus and most other organelles in order to free up space for haemoglobin. 2.4 million new red blood cells  are produced per second. The cells are produced in the bone marrow and circulate in the bloodstream for approximately 100-120 days before their components are recycled. Each lap of the circulatory system takes about 20 seconds. Red blood cells make up approximately 25% of the cells in the human body.
