Normal blood red cells are biconcave disks, approx. oval.
The tiny biconcave disks that carry oxygen are called red blood cells or erythrocytes. These cells transport oxygen from the lungs to the tissues in the body and play a crucial role in maintaining normal body function.
Red blood cells have a circular biconcave shape to increase surface area to volume ratio for faster absorption of oxygen in the bloodstream.
Erythrocytes, more commonly known as red blood cells.
Red blood cells are typically shaped like pinched disks, also known as biconcave discs. This unique shape allows them to carry oxygen efficiently through the bloodstream.
A red blood cell is disc-shaped with a thin center and thicker edges, resembling a biconcave disc. This shape allows for flexibility and more surface area for oxygen exchange.

These cells are red blood cells, also known as erythrocytes. Their biconcave shape allows for increased surface area for oxygen and carbon dioxide exchange. Red blood cells lack a nucleus to make more room for hemoglobin, the protein responsible for carrying oxygen.
Overall, mammalian red blood cells are remarkably flexible and deformable so as to squeeze through tiny capillaries, as well as to maximize their apposing surface by assuming a cigar shape (called a stack), where they efficiently release their oxygen load. Red blood cells are deformable, flexible, are able to adhere to other cells, and are able to interface with immune cells. In humans, mature red blood cells are flexible and oval biconcave disks which gives them the ability to get through the tiniest capillaries. The red blood cells of mammals are typically shaped as biconcave disks: flattened and depressed in the center, with a dumbbell-shaped cross section, and a torus-shaped rim on the edge of the disk. This distinctive biconcave shape optimizes the flow properties of blood in the large vessels.
