应该是食物进到胃里，消化了，经小肠和大肠，大肠里有一层象绒毛一样的东东，这些东东的作用可大了，它把经过胃消化后的食物里的营养都吸收了，然后把废物送到排泄系统，废水进膀胱，shi进肛门。:blink:
所以我们总是说肠胃咋滴、肝胆咋滴。。。。，这些都是有紧密相关滴，当胃不好，就影响到消化，消化不好，就加重肠的工作等等、、、、
年轻人不注重这些，到年纪大了，就知道了。
偶胡说八道一通，不知对不对。:blowzy:
学问真大啊，这个科普通俗易懂，长这么大才终于明白原来食物是这么消化的。

There is no egg in eggplant, nor ham in hamburger; neither apple or pine in pineapple. And while no one knows what is in a hotdog, you can be pretty sure it isn't canine. English muffins were not invented in England nor French fries in France. Sweetmeats are candies, while sweetbreads, which aren't sweet, are meat.
We take English for granted. But if we explore its paradoxes, we find that quicksand can work slowly, boxing rings are square, and guinea pig is neither from Guinea nor is it a pig.
And why is it that writers write, but fingers don't fing, grocers don't groce, and hammers don't ham? If the plural of tooth is teeth, why isn't plural of booth, beeth? One goose, 2 geese. So one moose, two meese? Is cheese the plural of choose? One mouse, 2 mice. One louse, 2 lice. One house, 2 hice? If teachers taught, why didn't preachers praught?
If a vegetarian eats vegetables, what does a humanitarian eat? Why do people recite at a play, and play at a recital? Ship by truck or car and send cargo by ship? Have noses that run and feet that smell? Park on driveways and drive on parkways?
How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can the weather be hot as heck one day and cold as heck another?
If a house burns up, it burns down. You fill in a form by filling it out and an alarm clock goes off by going on. You get in and out of a car, yet you get on and off a bus. When the stars are out, they are visible, but when the lights are out, they are invisible.
And why, when I wind up my watch, I start it, but when I wind up this essay, I end it?
English is a weird language ... it doesn't know if it is coming or going!!!
War never determines who's right. War only determines who's left.

No wonder the English language is so very difficult to learn:
We polish the Polish furniture.
He could lead if he would get the lead out.
A farm can produce produce.
The dump was so full it had to refuse refuse.
The soldier decided to desert in the desert.
The present is a good time to present the present to the President.
At the Army base, a bass was painted on the head of a bass drum.
The dove dove into the bushes.
I did not object to the object.
The insurance for the invalid was invalid.
The bandage was wound around the wound.
There was a row among the oarsmen about how to row.
They were too close to the door to close it.
The buck does funny things when the does are present.
They sent a sewer down to stitch the tear in the sewer line.
To help with planting, the farmer taught his sow to sow.
The wind was too strong to wind the sail.
After a number of Novocaine injections, my jaw got number.
I shed a tear when I saw the tear in my clothes.
I had to subject the subject to a series of tests.
How can I intimate this to my most intimate friend?
I spent last evening evening out a pile of dirt.

有关数学的几个小故事：
小的时候读过一个故事，名叫《效率专家爸爸》。他们家里养了12个孩子，是美国人。爸爸教他们早上起床扣扣子。为了训练他们的速度，爸爸做了一个测试，让孩子们从上往下扣，和从下往上扣，看看哪个速度快，很有趣味。
另一个故事是生产易拉罐饮料的。美国工厂的生产线上发现，成品里总有一些空罐子，找不到是什么规律。大工厂里的工程师们绞尽了脑汁，也想不出解决的办法，花了不少钱，用了很多的时间。同样的事发生在中国的南方乡镇企业，工程师也是束手无策，结果他们那个没读过多少书的厂长来了，拿着一个功率很大的电风扇，对着易拉罐们一吹， 哗啦啦，问题迎刃而解。这跟爱迪生让助手测算灯泡容积的故事很类似。
1923 年，福特公司有一台大型电机发生了故障，全公司所有工程师会诊了两三个月，也没有找出毛病在哪儿， 不得已， 公司邀请了专家斯泰因梅茨。 斯泰因梅茨在这台大型电机旁边搭了帐篷，整整检查了两昼夜，仔细地听电机发出的声音，反复进行各种计算，最后用梯子上上下下测量了一番， 就用粉笔在这台电机的某个地方划了条线作记号，然后对福特公司的经理说：“打开电机， 把作记号地方的线圈减少十六圈， 故障就可排除。”工程师们半信半疑地照办了，结果电机恢复了正常， 大家都为之一惊。 事后，斯泰因梅茨向福特公司要一万美金作为酬劳。有人嫉妒地说：“画一条线就要一万美金，这简直是勒索。”斯泰因梅茨听后一笑，提笔在付款单上写道： “用粉笔画一条线，一美元；知道在哪里画线，九千九百九十九美元！” （来自百度空间http://hi.baidu.com/tlycuhkwfjbmozq/item/374ad90d44c7fdea35990280）
数学里的故事，真是奥妙无穷。
