  2. White blood cell - Wikipedia

    en.wikipedia.org/wiki/White_blood_cell

    All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. [3] Leukocytes are found throughout the body, including the blood and lymphatic system. [4] All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and ...

    In a healthy adult person, approximately 10 11 –10 12 new blood cells are produced daily in order to maintain steady state levels in the peripheral circulation. [7] [8] All blood cells are divided into three lineages. [9] Red blood cells, also called erythrocytes, are the oxygen-carrying cells. Erythrocytes are functional and are released ...

    This is a list of immune cells, also known as white blood cells, white cells, leukocytes, or leucocytes. They are cells involved in protecting the body against both infectious disease and foreign invaders .

  6. Blood cell - Wikipedia

    en.wikipedia.org/wiki/Blood_cell

    Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and 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.

  7. Leukopoiesis - Wikipedia

    en.wikipedia.org/wiki/Leukopoiesis

    Leukopoiesis is a form of hematopoiesis in which white blood cells (WBC, or leukocytes) are formed in bone marrow located in bones in adults and hematopoietic organs in the fetus. White blood cells, indeed all blood cells, are formed from the differentiation of pluripotent hematopoietic stem cells which give rise to several cell lines with ...

  9. Leukocyte extravasation - Wikipedia

    en.wikipedia.org/wiki/Leukocyte_extravasation

    Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response.. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the circulatory system (extravasation) and towards the ...
