When an artery constricts, we call it vasoconstriction.

当动脉收缩时,我们称之为血管收缩。

生活小窍门

If you were to put yourself into a cold environment, we would experience in our vasculature, something known as vasoconstriction.

如果你把自己放在一个寒冷的环境中,我们的血管系统就会出现一种叫做血管收缩的现象。

全球10大刺激冒险

Blood shift is related to peripheral vasoconstriction.

血液转移与外周血管收缩有关。

精选英语短文

In another heat-preserving response -- called vasoconstriction -- blood vessels temporarily narrow.

在另一种称为血管收缩的保温反应中, 血管会暂时变窄。

心血管

During vasoconstriction, the artery gets smaller and offers increased resistance.

在血管收缩过程中,动脉变小,阻力增加。

医学专业英语:心血管内科学

Likewise, mild hypocapnia might be beneficial treatment as a temporary measure when treating cerebral edema, but hyperventilation could cause cerebral vasoconstriction.

同样,轻度低碳酸血症作为治疗脑水肿的临时措施可能是有益的治疗,但过度通气会导致脑血管收缩。

Osmosis-解剖与生理

Likewise, if you wanted to raise body temperature, vasoconstriction reduces blood flow, which means less heat gets lost through the surface of the skin.

同样,如果你想提高体温,血管收缩会减少血液流动,通过皮肤散失的热量会相应减少。

Crash Course 解剖生理学篇

Changes in diameter can be temporary, like during vasoconstriction or vasodilation — when the diameter increases or decreases, allowing more or less blood through.

直径的变化可能是暂时的,比如在血管收缩或舒张期间——直径增加或减少,允许或多或少的血液通过。

心血管

When an artery is in a state of vasoconstriction, the lumen of the artery gets smaller and blood flow decreases.

当动脉处于血管收缩状态时,动脉管腔变小,血流减少。

Crash Course 解剖生理学篇

And you know what else? While low blood pH does things like change the shape of your hemoglobin to deliver oxygen, high pH causes vasoconstriction.

你知道还会发生什么吗?虽然低血液 pH 值会改变血红蛋白的形状来输送氧气,但高 pH 值会导致血管收缩。

Crash Course 解剖生理学篇

This allows them to contract or relax through vasoconstriction and vasodilation, which we've talked about a lot in terms of the nervous system's stress response.

这使它们能够通过血管收缩和舒张来收缩或放松,我们已经就神经系统的压力反应谈了很多。

心血管

In this case, the cardio regulatory center responds to the low blood pressure by causing an increased heart rate and causing vasoconstriction.

在这种情况下,心脏调节中心会通过引起心跳加快和血管收缩来应对低血压。

Peripheral vasoconstriction is when blood vessels in the extremities constrict, moving blood from the limbs to oxygen sensitive organs like the heart, lungs, and brain.

外周血管收缩是指四肢的血管收缩,将血液从四肢转移到对氧敏感的器官,如心脏、肺和大脑。

心血管

The reverse is also true, if the radius of the vessel is reduced in half by vasoconstriction, then the blood flow would reduce by 16 fold.

反之亦然,如果通过血管收缩将血管半径缩小一半,那么血流将减少16倍。

Osmosis-血液肿瘤

Normally, after a cut and damage to the endothelium, or inner lining of blood vessel walls, there's an immediate vasoconstriction or narrowing of the blood vessel which limits the amount of blood flow.

正常情况下,血管壁内层的内皮细胞受到损伤后,血管会立刻收缩变窄,减少血流量。

Osmosis-心血管

Normally, the process starts with damage to the endothelium, or inner lining of blood vessel walls, after which there's an immediate vasoconstriction or narrowing of the blood vessel which limits the amount of blood flow.

通常,这一过程开始于血管内皮损伤,之后立即发生血管收缩,或者说通过收缩血管来限制血流量。

Osmosis-生殖

Also use of certain drugs are risk factors, like cocaine and methamphetamine because these can cause significant vasoconstriction of the placental blood vessels and an abrupt increase in blood pressure, increasing the risk of an abruption.

危险因素还有使用某些药物,如可卡因、脱氧麻黄碱,因为它们会导致胎盘血管的收缩和血压的突然升高,增加胎盘剥离的风险。

Crash Course 解剖生理学篇

That smooth muscle tissue is regulated in part by the nerve fibers of the autonomic nervous system, which can decrease the diameter of the lumen by contracting this middle layer during vasoconstriction, or expand it by relaxing during vasodilation.

平滑肌组织部分由自主神经系统的神经纤维调节,自主神经系统可以在血管收缩时通过收缩中间层来减小管腔直径,或者在血管舒张时通过放松来扩大管腔直径。
