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

意味着磷酸腔内，最终通过液排出。

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

最后是一层管腔柱状细胞，位于管腔内或腺体中央。

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

不过，些血管也可以舒张，即血管舒张，以扩大管腔直径，让更多的血液流过。

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

时，钙仍然腔内，但甲状旁腺激素也会影响远曲小管，增加对钙的再吸收。

5.But in this case, the sperm develop on the outer edge of the tubule, and progress inward toward the lumen.

但是种情况下，精子小管的外缘发育，并向内腔前进。

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

意味着磷酸了管腔内，最终通过液排出体外。

7.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、双腔管、带发声阀的管、金属管等。

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

水份较少时，管腔中钾离子浓度就会相应升高。

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

，钙仍然腔内，但是甲状旁腺激素也会影响远曲小管增加钙的再吸收。

10.They can put out up to 100 lumens per watt.

它们可以输出高达每瓦 100 流明。机翻

11.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。机翻

12.We call these luminescent substances, from the ancient Roman word, lumen, which means light.

我们称些发光物质为古罗马词“lumen”，意思是“光”。机翻

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

导致通过其内腔或中空中心的血流减少。

14.A narrow lumen means less blood and oxygen gets delivered to the kidney, resulting in ischemic injury to the nephron's glomerulus.

管腔狭窄意味着对肾的供血供氧减少，导致肾单位中肾小球的缺血性损伤。

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

内膜和中膜的细胞，都能从管腔内的血液中获取所需的营养物质。

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

碳酸氢能够中和酸性的食糜，还能提高肠腔内的pH值；也可以提高消化酶的活性。

17.But the other kind — the type B's — get pushed down the tubule toward the lumen, and turn into primary spermatocytes.

但是另一种，B 型，则是沿着细管进入管腔，然后变成初级精母细胞。

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

动脉内壁或者说内膜产生撕裂，血流随之进入管壁的假腔中。

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

此外，些利剂也允许更多的水保管腔内，造成管腔内相对低的钾浓度。

20.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​​共可产生高达 48,000 流明的光，配有多达 27 个 LED 灯。机翻
