  2. Endothelium-derived hyperpolarizing factor - Wikipedia

    en.wikipedia.org/wiki/Endothelium-derived...

    The endothelium maintains vascular homeostasis through the release of active vasodilators.Although nitric oxide (NO) is recognized as the primary factor at level of arteries, increased evidence for the role of another endothelium-derived vasodilator known as endothelium-derived hyperpolarizing factor (EDHF) has accumulated in the last years.

  3. Shock (circulatory) - Wikipedia

    Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system.Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1]

  4. Vasculitis - Wikipedia

    Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3]

  5. Atheroma - Wikipedia

    en.wikipedia.org/wiki/Atheroma

    An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [1] [2]The material consists of mostly macrophage cells, [3] [4] or debris, containing lipids, calcium and a variable amount of fibrous connective tissue.

  6. Endothelium-derived relaxing factor - Wikipedia

    en.wikipedia.org/wiki/Endothelium-derived...

    Nitric Oxide (NO), the principal EDRF. The Endothelium-derived relaxing factor (EDRF) is a strong vasodilator produced by cardiac endothelial cells in response to stress signals such as high levels of ADP accumulation or hypoxia.

  7. Livedo reticularis - Wikipedia

    en.wikipedia.org/wiki/Livedo_reticularis

    Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().

  8. Dental plaque - Wikipedia

    en.wikipedia.org/wiki/Dental_plaque

    Dental plaque is a biofilm that attaches to tooth surfaces, restorations and prosthetic appliances (including dentures and bridges) if left undisturbed.Understanding the formation, composition and characteristics of plaque helps in its control. [6]
