  2. White blood cell - Wikipedia

    en.wikipedia.org/wiki/White_blood_cell

    An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.

  4. 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. [1]

    about 7 μm – diameter of human red blood cells [88] 3–8 μm – width of strand of spider web silk [89] 5–10 μm – width of a chloroplast [90] 8–11 μm – size of a ground-level fog or mist droplet [91] [note 4] 7–12 μm – the diameter of human white blood cells; 8–10 μm – the diameter of human macrophages

  6. Monocyte - Wikipedia

    en.wikipedia.org/wiki/Monocyte

    With a diameter of 15–22 μm, monocytes are the largest cell type in peripheral blood. [ 2 ] [ 3 ] Monocytes are mononuclear cells and the ellipsoidal nucleus is often lobulated/indented, causing a bean-shaped or kidney-shaped appearance. [ 4 ]

  7. Lymphocyte - Wikipedia

    en.wikipedia.org/wiki/Lymphocyte

    A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...

  8. Peripheral blood mononuclear cell - Wikipedia

    en.wikipedia.org/wiki/Peripheral_blood...

    A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round nucleus. [1] These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei. In humans, lymphocytes make up ...
