  2. Lipid-laden alveolar macrophage - Wikipedia

    en.wikipedia.org/.../Lipid-laden_alveolar_macrophage

    [2] [9] Lipid-laden alveolar macrophages have been reported in cases of vaping-associated pulmonary injury. [10] [1] [11] The lipid-laden macrophage index (LLMI) can be calculated by counting 100 macrophages in a BAL specimen treated with a lipid stain and scoring each macrophage from 0 to 4 based on the amount of lipids present in the cell.

  3. Foam cell - Wikipedia

    en.wikipedia.org/wiki/Foam_cell

    Foam cells, also called lipid-laden macrophages, are a type of cell that contain cholesterol. These can form a plaque that can lead to atherosclerosis and trigger myocardial infarction and stroke. [1] [2] [3] Foam cells are fat-laden cells with a M2 macrophage-like phenotype.

  4. Kupffer cell - Wikipedia

    en.wikipedia.org/wiki/Kupffer_cell

    Kupffer cells, also known as stellate macrophages and Kupffer–Browicz cells, are specialized cells localized in the liver within the lumen of the liver sinusoids and are adhesive to their endothelial cells which make up the blood vessel walls. Kupffer cells comprise the largest population of tissue-resident macrophages in the body.

  5. Alveolar macrophage - Wikipedia

    en.wikipedia.org/wiki/Alveolar_macrophage

    Micrograph showing hemosiderin-laden alveolar macrophages, as seen in a pulmonary hemorrhage. H&E stain. An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of the alveoli in the lungs, but separated from their walls.

  6. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    The digestive system has a complex system of motility and secretion regulation which is vital for proper function. This task is accomplished via a system of long reflexes from the central nervous system (CNS), short reflexes from the enteric nervous system (ENS) and reflexes from GI peptides working in harmony with each other. [4]

  7. Goblet cell - Wikipedia

    en.wikipedia.org/wiki/Goblet_cell

    Goblet cells are simple columnar epithelial cells, having a height of four times that of their width. The cytoplasm of goblet cells tends to be displaced toward the basal end of the cell body by the large mucin granules, which accumulate near the apical surface of the cell along the Golgi apparatus, which lies between the granules and the nucleus.

  8. Giant cell - Wikipedia

    en.wikipedia.org/wiki/Giant_cell

    Giant cells are also known to develop when infections are present. They were first observed as early as the middle of the last century, but it is not fully understood why these reactions occur. In the process of giant cell formation, monocytes or macrophages fuse together, which could cause multiple problems for the immune system. [citation needed]

  9. Stomach - Wikipedia

    en.wikipedia.org/wiki/Stomach

    In the human digestive system, a bolus (a small rounded mass of chewed up food) enters the stomach through the esophagus via the lower esophageal sphincter. The stomach releases proteases (protein-digesting enzymes such as pepsin ), and hydrochloric acid , which kills or inhibits bacteria and provides the acidic pH of 2 for the proteases to work.
