The puborectalis forms a sling-like formation around the rectum called the anorectal angle.

耻骨直肠肌与直肠形成类似吊索的结构，叫做肛肠角。

Both of these problems make the anorectal angle more acute and it becomes difficult to expel waste.

这种情况大多是因为分娩或是人体老化，两者都会使肛肠角更小，粪便也会难以排出。

With your buttocks firmly on the toilet seat, you can elevate your feet on a stool and lean forwards with a straight back, which straightens the anorectal angle and eases the passage of waste.

臀部应牢坐在马桶上时，你可以把脚抬放在小凳子上，向前倾让背挺直，这样会挺直肛肠角让排便更通畅。
