Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
Schistocytes are fragmented red blood cells that can take on different shapes. They can be found as triangular, helmet shaped, or comma shaped with pointed edges. Schistocytes are most often found to be microcytic with no area of central pallor.
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.
Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. A poikilocyte is an abnormally-shaped red blood cell. [1] Generally, poikilocytosis can refer to an increase in abnormal red blood cells of any shape, where they make up 10% or more of the total population of red blood cells.
Elliptocytes, also known as ovalocytes or cigar cells, are abnormally shaped red blood cells that appear oval or elongated, from slightly egg-shaped to rod or pencil forms. They have normal central pallor with the hemoglobin appearing concentrated at the ends of the elongated cells when viewed through a light microscope .
Erythrocyte aggregation is the reversible clumping of red blood cells (RBCs) under low shear forces or at stasis. Stacked red blood cells flow across drying slide. Erythrocytes aggregate in a special way, forming rouleaux. Rouleaux are stacks of erythrocytes which form because of the unique discoid shape of the cells in vertebrate body. The ...
Crenation is also used to describe a feature of red blood cells. These erythrocytes look as if they have projections extending from a smaller central area, like a spiked ball. The crenations may be either large, irregular spicules of acanthocytes, or smaller, more numerous, regularly irregular projections of echinocytes. [3]
One theory regarding dacrocyte formation is that red blood cells containing various inclusions undergo "pitting" by the spleen to remove these inclusions, and in the process, they can be stretched too far to return to their original shape. [2]
