Definition of contractility in US English:



Physiology Biology
  • See contractile

    • ‘Activation of the adrenergic system triggers the release of catecholamines, which stimulate contractility, heart rate, and blood pressure and promote myocyte hypertrophy.’
    • ‘Studies performed in undernourished patients without respiratory disease have suggested that malnutrition may impair skeletal muscle contractility.’
    • ‘Decrease myocardial oxygen demand by decreasing heart rate, systolic blood pressure, and contractility.’
    • ‘Hypercapnia can also decrease respiratory muscle contractility, leading to a vicious circle of carbon dioxide retention.’
    • ‘The muscular layers create vein contractility, which maintains venous tone.’
