Oval convex discs

One-sided convex disc

Oval biconcave disks

Sphere

In humans, mature red blood cells are flexible and oval biconcave discs. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin; they can be viewed as sacks of hemoglobin, with a plasma membrane as the sack. Approximately 2.4 million new erythrocytes are produced per second in human adults.
