  2. Red blood cell - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell

    The size of red blood cells varies widely among vertebrate species; red blood cell width is on average about 25% larger than capillary diameter, and it has been hypothesized that this improves the oxygen transfer from red blood cells to tissues. [15]

  3. Red blood cell distribution width - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell...

    Red blood cell distribution width (RDW), as well as various types thereof (RDW-CV or RCDW and RDW-SD), is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. [1] Red blood cells have an average volume of 80–100 femtoliters, but individual cell volumes vary even in ...

  4. Price-Jones curve - Wikipedia

    en.wikipedia.org/wiki/Price-Jones_curve

    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]

  5. Blood cell - Wikipedia

    en.wikipedia.org/wiki/Blood_cell

    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 ...

  6. Microcytic anemia - Wikipedia

    en.wikipedia.org/wiki/Microcytic_anemia

    The MCV is the average red blood cell size. In microcytic anemia, the red blood cells (erythrocytes) contain less hemoglobin and are usually also hypochromic, meaning that the red blood cells appear paler than usual. This can be reflected by a low mean corpuscular hemoglobin concentration (MCHC), a measure representing the amount of hemoglobin ...

  7. Macrocytosis - Wikipedia

    en.wikipedia.org/wiki/Macrocytosis

    Macrocytosis is a condition where red blood cells are larger than normal. [1] These enlarged cells, also known as macrocytes, are defined by a mean corpuscular volume (MCV) that exceeds the upper reference range established by the laboratory and hematology analyzer (usually >110 fL). [2]

  8. Mean corpuscular volume - Wikipedia

    en.wikipedia.org/wiki/Mean_corpuscular_volume

    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.

  9. Fåhræus effect - Wikipedia

    en.wikipedia.org/wiki/Fåhræus_effect

    The Fåhræus effect (/ f ɑː ˈ r eɪ. ə s /) is the decrease in average concentration of red blood cells in human blood as the diameter of the glass tube in which it is flowing decreases. In other words, in blood vessels with diameters less than 500 micrometers, the hematocrit decreases with decreasing capillary diameter.
