Having little water in the lumen, creates a relatively high potassium concentration in the lumen.

水份较少时，管中钾离子浓度就会相应升高。

Also, though, these vessels can relax or vasodilate, and the lumen's diameter increases, which allows more blood flow.

不过，这些血管也舒张，即血管舒张，扩大管直径，让更多的血液流过。

They can put out up to 100 lumens per watt.

它们出高达每瓦 100 流明。

Finally, there's an inner ring of luminal columnar cells, which are within the lumen or center of the gland.

最后是一层管柱状细胞，位于管腺体中央。

An equivalent CFL will get you way more, between 55 and 70 lumens per watt.

等效的 CFL 将为您提供更多，每瓦 55 至 70 流明。

This causes a decreased blood flow through its lumen, or hollow center.

这导致通过其中空中心的血流减少。

So this means that phosphate is left in the lumen and eventually gets sent out in the urine.

这意味着磷酸盐留在了管，最终通过尿液排出体外。

Bicarbonate helps neutralize the acidic chyme, and raising the pH in the intestinal lumen also helps digestive enzymes work more effectively.

碳酸氢盐能够中和酸性的食糜，还能提高的pH值；这也提高消化酶的活性。

Different varieties of tracheostomy tubes include cuffed, non cuffed, double lumen tubes, tubes with speaking valves, metallic tubes, and so on.

不同种类的气管造口管包括带套囊的管、没有套囊的管、双管、带发声阀的管、金属管等。

In addition, these diuretics also allow more water to remain in the lumen, creating a relatively low potassium concentration in the lumen.

此外，这些利尿剂也允许更多的水保留在管，造成管相对低的钾浓度。

This means that phosphate is left in the lumen and eventually gets sent out in the urine.

这意味着磷酸盐留在，最终通过尿液排出。

The CR Revelation lighting package can produce up to 48,000 lumens in total, with as many as 27 LED lights.

CR Revelation 照明套件总​​共产生高达 48,000 流明的光，配有多达 27 个 LED 灯。

Both the cells of the tunica intima and tunica media generally get the nutrients they need from the blood in the lumen.

膜和中膜的细胞，都能从管的血液中获取所需的营养物质。

Now, that calcium's still in the lumen, but parathyroid hormone also affects the distal convoluted tubule and increases calcium reabsorption.

这时，钙仍然在，但甲状旁腺激素也会影响远曲小管，增加对钙的再吸收。

A dissection is where the inner wall, or intima, gets a tear, and blood tracks into a false lumen in the vessel wall.

动脉壁者说膜产生撕裂，血流随之进入管壁的假中。

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，动脉管变小，血流减少。

Aldosterone increases sodium channels on the lumen side of the principal cell and sodium-potassium pumps on the basolateral side of the principal cells.

它增加主细胞面钠离子、钾离子通道和基底面的钠-钾泵的数量。

When the artery is in a state of vasodilation, the lumen of the artery gets bigger and blood flow increases.

当动脉处于舒张状态时，动脉管变大，血流增加。

As the mucosa and epithelium are destroyed, blood and serum may be released into the lumen, which contributes to blood seen on the stools.

因为粘膜和上皮组织受到了破坏，血液血浆流入当中，进而导致肉眼见的血便。

Now, that calcium's still in the lumen, though, but parathyroid hormone also affects the distal convoluted tubule and increases calcium reabsorption.

现在，钙仍然在，但是甲状旁腺激素也会影响远曲小管增加钙的再吸收。
