Cardiovascular (7)

Cards (8)

  • Carbonic anhydrase

    Catalyzes carbon dioxide and water to carbonic acid
  • Active hyperaemia

    Increased blood flow during increased metabolic activity due to decreased oxygen and increased metabolites
  • Flow autoregulation
    Ability of an organ to maintain constant blood flow despite changes in perfusion pressure, restored by local dilation of blood vessels
  • Adrenaline
    Released from adrenal medulla, vasoconstrictor in most vascular beds but vasodilation in skeletal muscle predominates
  • Angiotensin 2

    Vasoconstrictor, part of renin-angiotensin system
  • Vasopressin
    Vasoconstrictor, released from posterior pituitary
  • Valsalva manoeuvre

    Attempting to forcibly exhale while keeping mouth and nose closed, used to evaluate heart condition and correct abnormal heart rhythms or relieve chest pain
  • Exercise
    Increases metabolic demand, increases blood flow to exercising muscles, increases heat production and increases blood flow to skin, increases cardiac output, affects blood pressure and pulse pressure
