Formation of RBCs
An erythrocyte (erythro = red) is a fully mature red cell found in the peripheral blood. Although highly specialized,
it is little more than a small bag – a membrane surrounding a ...
Blood Cells and Platelets
The blood has three types of formed elements: erythrocytes (red blood cells), leukocytes (white blood cells),
and platelets or thrombocytes .
Erythrocytes: Also called red blood ...
Components of Blood
Blood consists of plasma and formed elements. Plasma, which makes up about 55% of blood, is the straw-colored clear liquid in which cellular elements and dissolved substances (solutes) ...
Functions of Blood
Blood is essential to all cell life. It distributes oxygen, nutrients, electrolytes, hormones, and enzymes throughout the body. Table below shows four major functions of blood.
Jordans Anomaly in White Blood Cells

Reticulocytes smear
Supravital stain of a smear of human blood from a patient with hemolytic anemia. The reticulocytes are the cells with the dark blue dots and curved linear structures (reticulum) in ...
Summary of Abnormal Red Blood Cell Morphologies and Disease States
Before we start with the abnormal morphologies, let’s talk about normal morphology of Red Blood Cells.
Normal mature RBC are biconcave, round discs that are about 6 – 8 in ...
NRBCs and Howell Jolly body
A Howell Jolly body is seen in one red cell (A). Also present are two nucleated red blood cells (B).
Nucleated red blood cells (NRBCs): they may look at fist similar to small mature ...

Morphologic Evaluation of Red Blood Cells
Shape: Biconcave disc.
Diameter : 7 ~ 8 μm.
Central pallor occupy 1/3 rd of total cell diameter.
Size : approx. same as nucleus of mature small lymphocyte.
Smear from patient with Multiple Myeloma (M.M)
Smear from patient with Multiple Myeloma display an abundance of plasma cells.
RBC will often be seen in rouleaux formation stacked like poker chips.
