Codocytes, also known as target cells, are red blood cells that have the appearance of a shooting target with a bullseye. In optical microscopy these cells appear to have a dark center (a central, hemoglobinized area) surrounded by a white ring (an area of relative pallor), followed by dark outer (peripheral) second ring containing a band of ...
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 ...
Defective red cell metabolism (as in glucose-6-phosphate dehydrogenase deficiency and pyruvate kinase deficiency). [11] [12] Wilson's disease may infrequently present with hemolytic anemia without due to excessive inorganic copper in blood circulation, which destroys red blood cells (though the mechanism of hemolysis is still unclear). [13]
A human peripheral blood smear; NRBCs are visible as larger cells with dark centers. A nucleated red blood cell ( NRBC ), also known by several other names , is a red blood cell that contains a cell nucleus .
Red and white human blood cells as seen under a microscope using a blue slide stain The darker red blood syringes have deoxygenated blood, whereas the brighter red have oxygenated blood. Red blood cells or erythrocytes primarily carry oxygen and collect carbon dioxide through the use of hemoglobin. [2] Hemoglobin is an iron-containing protein ...
The colour blood red is a dark shade of the colour red meant to resemble the colour of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma). [2] It is the iron in hemoglobin specifically that gives blood its red colour. The actual colour ranges from crimson to a dark brown-blood depending on ...
Pappenheimer bodies (Peripheral Blood / May-Grünwald Giemsa and Prussian blue stain) Pappenheimer bodies are abnormal basophilic granules of iron found inside red blood cells on routine blood stain. [1] They are a type of inclusion body composed of ferritin aggregates, or mitochondria or phagosomes containing aggregated ferritin. They appear ...
The formed elements are the two types of blood cell or corpuscle – the red blood cells, (erythrocytes) and white blood cells (leukocytes), and the cell fragments called platelets [12] that are involved in clotting. By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.
