Red Blood Cell

Erythrocytes do not contain a nucleus. They do contain haemoglobin, which fills almost the entire cytoplasm. Erythrocytes are unable to move actively, but they are remarkably elastic and can withstand deformation. They are typically biconcave disks although their shape is influenced by osmotic forces.

The average diameter of the disk is ~7 µm.

Since erythrocytes can be found in the vast majority of histological sections - in small numbers even in perfused tissues - they will often allow us to estimate the size of other structures or cells.

Mature erythrocytes do not contain organelles, and their cytoplasm looks fairly homogenous - even in the EM
