Once that bolus of food gets swallowed through the pharynx it goes into the esophagus.

经咽部被吞咽后，就进了管。

The saliva helps to make the food compact down into a soft, warm ball, called a “bolus”.

在唾液的帮助下，物被压缩成柔软、温暖的小球，称为“”。

Bolus 1,000 milligrams of IV iron.

推一千毫克铁剂。

He's gotten 40cc per kilogram bolus through a sterile I.O. line.

经无菌髓内注射每公斤体重40毫升的药物。

The O.R. Can't wait.Alex, find burke and bolus a liter of saline, hang a unit of blood.

手术不能再拖了 Alex去找Burke 准备一升生理盐水 一个单位的血液。

Alright, as a quick recap, food is ingested through the mouth, chewed by the teeth, mixed with saliva and turned into a bolus.

得！快速回顾一下～物由口，由牙齿咀嚼，与唾液混合后形成。

Together, they perform what’s called peristalsis, which is a series of coordinated wave-like muscle contractions that helps squeeze the food bolus in one direction.

内环肌与外纵肌的活动共同形成了肠道的蠕动；肠蠕动就是指一系列协同进行的平滑肌的波状收缩，可以挤压，确保物向前移动。

The bolus is then moved by peristalsis through the esophagus and into the stomach, where hydrochloric acid is secreted and pepsin begins the digestion process.

在管的蠕动下被送胃内；胃内随即分泌胃酸，并在胃蛋白酶的作用下开始进行消化。

Working on it. - Run that bolus. Get me epi.

正在努力 -给他大剂量的 快把肾上腺素给我。

Now, the esophagus has a particularly thick muscularis externa that propels the bolus of food down to the esophageal sphincter , which opens, allowing the bolus to pass into the stomach.

管的肌层非常厚，这有助于管将推向管括约肌；管括约肌适时开放，以便进胃部。
