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

内和中细胞，都能从管腔内血中获取所需营养物质。

Increase in cAMP causes chloride channels on the cells to increase the secretion of chloride into the lumen while inhibiting the channels that let sodium and chloride back into the cell.

In the gut, there's a layer of smooth muscle just under the submucosa, which sits under the mucosa, which is the innermost layer of the gut nearest to the lumen.

在肠道，黏下之下有一平滑肌，黏下即位于黏下，而黏是肠道最内（离肠腔最近）。

Cortisol also helps to maintain the blood pressure by increasing the sensitivity of peripheral blood vessels to catecholamines- like epinephrine and norepinephrine, and this narrows the blood vessel lumen.

皮质醇也帮助维持血压，增加周围血管对如肾上素和去甲肾上素等儿茶酚胺敏感，这会缩小血管腔。

This will compress the structures within, and the first ones to feel the effect of compression are the veins because the pressure inside their lumen is normally low.

这会压迫其内部结构；最先受到影响是静脉，因为静脉内压力通常较低。

These are the glands that secrete the majority of the mucus into the lumen of the bronchi, helping to catch and filter out particles and pathogens.

So one hour of work translates into 20,000 more lumen hours of light that it did just in the time since this institution was founded.

因此，一小时工作转化成2万多光流明时，而这是在美国国家科学院成立以来这么短时间内做到。

Most of your blood vessels share a similar structure consisting of three layers of tissue surrounding the open space, or lumen, that actually holds the blood.

你大多数血管都有一个相似结构，由三组织组成，围绕着开放空间或内腔，实际上容纳血。

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

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

不同种类气管造口管包括带套囊管、没有套囊管、双腔管、带发声阀管、金属管等。

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

这时，钙仍然在腔内，但甲状旁激素也会影响远曲小管，增加对钙再吸收。

Anatomists call these layers " tunics, " and the innermost section is the tunica intima — which should be pretty easy to remember because, you know, it has like intimate contact with the lumen. It's like your circulatory underpants.

解剖学家称这些为束腰外衣，最里面部是内——这应该很容易记住，因为，你知道，它和内腔有亲密接触。就像你循环内裤。

Since this is continuously happening, the scar becomes bigger and bigger, and together with the edema, they turn the wall thicker, and the lumen through which the food passes becomes smaller - which is called esophageal stenosis.

由于这种情况不断发生，疤痕组织变得越来越大，并伴随水肿，它们会使壁变厚，食物通过腔变小，这就是食管狭窄。

So, the abnormally high levels of luminal sodium and chloride disrupt the osmotic balance between the intestines and surrounding tissue; and water, bicarbonate, and potassium rush into the lumen of the intestines as a result.

因此，异常高水平管腔钠和氯破坏了肠道和周围组织之间渗透平衡；水、碳酸氢盐和钾因而涌进肠腔。

In the bronchioles you've got the lumen, the mucosa which includes the inner lining of epithelial cells as well as the lamina propria, and the submucosa which is where the smooth muscle lives.

在细支气管内，有腔体、粘（包括上皮细胞内、固有），以及粘下，也就是平滑肌所在地方。

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食糜，还能提高肠腔内pH值；这也可以提高消化酶活。

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供血供氧减少，导致肾单位中肾小球缺血损伤。

Ulcerative colitis is a type of inflammatory bowel disease that tends to form ulcers along the inner-surface or lumen of the large intestine, including both the colon and the rectum.

溃疡结肠炎是炎症肠病其中一种类型，其主要表现为沿着大肠内面或管腔形成溃疡，这里所说大肠包括结肠和直肠。

In peristalsis, the smooth muscles of the walls of your digestive organs take turns contracting and relaxing to squeeze food through the lumen, or cavity, of your alimentary tract.

在蠕动中，消化器官壁平滑肌轮流收缩和放松，以将食物挤出消化道腔或腔。

In hypertension, the walls of arteries supplying the kidney begin to thicken in order to withstand the pressure, and that results in a narrow lumen.

在高血压下，供应肾动脉血管壁为了承受更高血压而增厚，造成血管腔狭窄。
