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 ...
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.
Microcytosis or microcythemia [1] is a condition in which red blood cells are unusually small as measured by their mean corpuscular volume. [2] When associated with anemia, it is known as microcytic anemia.
Non-sideropenic hypochromic anemia also known as Normochromic Normocytic Anemia [1] is a kind of anemia in which the red blood cells in circulation have a normal red color (normochromic) and the same size . Normocytic normochromic anemia is most commonly caused by a variety of chronic infections and systemic diseases. [2]
Red blood cells are much smaller than most other human cells. RBCs are formed in the red bone marrow from hematopoietic stem cells in a process known as erythropoiesis. In adults, about 2.4 million RBCs are produced each second. The normal RBCs count is 4.5 to 5 millions per cu.mm. RBCs have a lifespan of approximately 100-120 days.
Note the increased central pallor of the red blood cells. Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. (Hypo- refers to less, and chromic means colour.) A normal red blood cell has a biconcave disk shape and will have an area of pallor in its center when viewed microscopically.
Reticulocytes are also relatively large, a characteristic that is described by the mean corpuscular volume. 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 the cytoplasm.
This particular cause of acanthocytosis (also known as abetalipoproteinemia, apolipoprotein B deficiency, and Bassen-Kornzweig syndrome) is a rare, genetically inherited, autosomal recessive condition due to the inability to fully digest dietary fats in the intestines as a result of various mutations of the microsomal triglyceride transfer ...
