The ceca are home to millions of microscopic organisms.

是数百万微生物的家园。

This is called the cecum and this worm-like structure coming off of it is known as the appendix.

这被，从脱的蠕虫状结构被阑尾。

Hanging off from the cecum is the appendix, a small organ with no clear function.

一个没有明确功能的小器官-阑尾，悬挂在上。

The ascending colon, extending from the cecum to the upper abdominal area.

升结，从延伸到上腹部。

When chyme hits the cecum, it's met by trillions of bacteria that colonize the large intestine - they're collectively called the gut microbiome.

一旦食糜进入，便立即与数以万亿计的细菌接触；这些细菌定植于大，它们统道微生物。

Extending from the end of the ileum to the anus, it is divided into four parts: cecum, colon, sigmoid colon and rectum.

大从回末端延伸到肛门，并分四个部分：，结，乙状结和直。

Occasionally, the diverticulum can invert and stick back into the intestine, allowing it to serve as a lead point that again drags the ileum into the cecum.

憩室偶尔会翻入腔内，成套叠的起点，把回拽入。

Now all you have to do is invert the stump into the cecum and simultaneously pull up on the purse strings, but be careful not to...break them.

现在你要把剩下的残余反转进，并且同时把它拉起来打个结，但是要小心，不要… … 把它们碰破了。

So! Once the chyme has worked through your small intestine, it passes through the ileocecal valve and hits the cecum, the first part of the large intestine, where, congratulations, your food is now officially feces!

所以！一旦食糜通过你的小，它就会穿过回瓣，到达，大的第一部分，恭喜你，你的食物现在正式变成粪便了！
