There is an immense size variation in vertebrate red blood cells, as well as a correlation between cell and nucleus size. Mammalian red blood cells, which do not contain nuclei, are considerably smaller than those of most other vertebrates. [10] Mature red blood cells of birds have a nucleus, however in the blood of adult females of penguin ...
A blood smear can be used to view individual red blood cells. The diameter of each red blood cell can be measured, which is usually analogous to volume. [2] This is usually performed automatically by particle counters. [2] [4] Data is then converted into a histogram. [1] This can be used to assess red blood cell distribution width (RDW). [1] [4]
about 7 μm – diameter of human red blood cells [88] 3–8 μm – width of strand of spider web silk [89] 5–10 μm – width of a chloroplast [90] 8–11 μm – size of a ground-level fog or mist droplet [91] [note 4] 7–12 μm – the diameter of human white blood cells; 8–10 μm – the diameter of human macrophages
Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40–45% of its volume. Red blood cells are circular ...
The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.
The mean corpuscular volume, or mean cell volume (MCV), is a measure of the average volume of a red blood corpuscle (or red blood cell). The measure is obtained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit ), and dividing that product by the number of erythrocytes (red blood cells) in that volume.

Life cycle of a red blood cell. Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. [1]
