Blood Cell

A blood cell, also called a haematocyte, is a cell produced by haematopoiesis and normally found in blood. In mammals, these fall into three general categories:

  • Red blood cells – Erythrocytes
  • White blood cells – Leukocytes
  • Platelets – Thrombocytes.

Together, these three kinds of blood cells add up to a total 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid component of blood. This volume percentage (e.g., 45%) of cells to total volume is called hematocrit, determined by centrifuge or flow cytometry. Hemoglobin (the main component of red blood cells) is an iron-containing protein that facilitates transportation of oxygen and other respiratory gases to tissues.

Famous quotes containing the words cell and/or blood:

    She that but little patience knew,
    From childhood on, had now so much
    A grey gull lost its fear and flew
    Down to her cell and there alit,
    And there endured her fingers’ touch
    And from her fingers ate its bit.
    William Butler Yeats (1865–1939)

    His white head hung out like a carpet bag
    and his crotch turned blue as a blood blister,
    and Godfather death, as it is written,
    put a finger on his back
    for the big blackout,
    the big no.
    Anne Sexton (1928–1974)
