Exempel på hur man kan använda VASOCONSTRICTION i en mening

• Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
• Renin (etymology and pronunciation), also known as an angiotensinogenase, is an aspartic protease protein and enzyme secreted by the kidneys that participates in the body's renin-angiotensin-aldosterone system (RAAS)—also known as the renin-angiotensin-aldosterone axis—that increases the volume of extracellular fluid (blood plasma, lymph, and interstitial fluid) and causes arterial vasoconstriction.
• Ergot alkaloids, the active compounds produced by the ergot fungus, can cause severe vasoconstriction, leading to symptoms like gangrene and convulsions.
• Many of these substances are neurotransmitters released by perivascular nerves of the autonomic nervous system Baroreceptors sense blood pressure and allow adaptation via the mechanisms of vasoconstriction or vasodilation to maintain homeostasis.
• It also implies local hypoxia in a part of a body resulting from constriction (such as vasoconstriction, thrombosis, or embolism).
• Angiotensin II binds to the type 1 angiotensin II receptor (AT1), which sets off a number of actions that result in vasoconstriction and therefore increased blood pressure.
• Vascular compliance is determined by the muscle tone in the smooth muscle tissue of the tunica media and the elasticity of the elastic fibers there, but the muscle tone is subject to continual homeostatic changes by hormones and cell signaling molecules that induce vasodilation and vasoconstriction to keep blood pressure and blood flow within reference ranges.
• As such, an increase in sodium chloride concentration would result in vasoconstriction of afferent arterioles, and reduced paracrine stimulation of juxtaglomerular cells.
• The toxicity of DOB is not fully known, although high doses may cause serious vasoconstriction of the extremities.
• AII causes arterial vasoconstriction and hypertension, resulting in an increase in afterload, increasing the resistance against which the heart works.
• A cold-stimulus headache is thought to be the direct result of the rapid cooling and rewarming of the capillaries in the sinuses leading to periods of vasoconstriction and vasodilation.
• Rizatriptan and other triptans can cause vasoconstriction, they are contraindicated in people with cardiovascular conditions.
• Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and anxiety.
• Vasodilation and vasoconstriction are complex phenomena; they are functions not merely of the fluid mechanics of pressure and tissue elasticity but also of active homeostatic regulation with hormones and cell signaling, in which the body produces endogenous vasodilators and vasoconstrictors to modify its vessels' compliance.
• Killip class IV describes individuals in cardiogenic shock or hypotension (measured as systolic blood pressure lower than 90 mmHg), and evidence of peripheral vasoconstriction (oliguria, cyanosis or sweating).
• The process of thermoregulation, occurs to protect vital organs from the cold temperatures, promoting increased blood flow and delivery of nutrients throughout the body via vasoconstriction and vasodilation of the blood vessels.
• Cool, clammy, and mottled skin (cutis marmorata) due to vasoconstriction and subsequent hypoperfusion of the skin.
• Stress and cold temperature induce an exaggerated vasoconstriction of the small arteries, arterioles, and thermoregulatory vessels of the skin of the digits.
• Hypoxic pulmonary vasoconstriction (HPV) occurs diffusely, leading to arterial vasoconstriction in all areas of the lung.
• Like most stimulants, caffeine causes vasoconstriction, so the vasodilation effects from concomitant histamine can counteract this.
