    Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...

  4. Neutrophil extracellular traps - Wikipedia

    en.wikipedia.org/wiki/Neutrophil_extracellular_traps

    NETs formed in blood vessels can catch circulating bacteria as they pass through the vessels. Trapping of bacteria under flow has been imaged directly in flow chambers in vitro and intravital microscopy demonstrated that bacterial trapping occurs in the liver sinusoids and lung capillaries (sites where platelets bind neutrophils).

  5. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).

  6. Phagocyte - Wikipedia

    en.wikipedia.org/wiki/Phagocyte

    TNF-α is an important chemical that is released by macrophages that causes the blood in small vessels to clot to prevent an infection from spreading. [132] If a bacterial infection spreads to the blood, TNF-α is released into vital organs, which can cause vasodilation and a decrease in plasma volume; these in turn can be followed by septic ...

  7. Endothelium - Wikipedia

    en.wikipedia.org/wiki/Endothelium

    The endothelium is a thin layer of single flat cells that line the interior surface of blood vessels and lymphatic vessels. [1] Endothelium is of mesodermal origin. Both blood and lymphatic capillaries are composed of a single layer of endothelial cells called a monolayer. In straight sections of a blood vessel, vascular endothelial cells ...

  8. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body. They also take waste and carbon dioxide away from the tissues. [2] Some tissues such as cartilage, epithelium, and the lens and cornea of the eye are not supplied with blood vessels and are termed avascular.

  9. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    Bacterial microcompartments are widespread, organelle-like structures that are made of a protein shell that surrounds and encloses various enzymes. provide a further level of organization; they are compartments within bacteria that are surrounded by polyhedral protein shells, rather than by lipid membranes. These "polyhedral organelles ...
