问题 填空题

某人的尿液中有血细胞和蛋白质,说明其肾脏发生病变的部位是______.

答案

当血液流经肾小球和肾小囊壁时,除血细胞和大分子的蛋白质外,血浆中的一部分水、无机盐、葡萄糖和尿素等物质被过滤进入肾小囊腔形成原尿,当原尿流经肾小管时全部的葡萄糖、大部分的水和部分无机盐被肾小管重吸收,而剩下的水和无机盐、尿素等形成了尿液;尿液中出现红细胞、蛋白质、葡萄糖属于不正常现象,可能是由于肾小球发生病变导致其通透性增大,可能使部分血细胞和大分子蛋白质进入原尿.
故答案为:肾小球

I can still remember the first day when I met my best friend. I hid behind my mother and she hid behind her grandmother,   1  to look at each other. But we soon lost the  2  and started playing with each other. In the 7th grade, I first lost touch with her. She was   3  family problems and I deserted her to be with the “cooler people”.   4  of my new friends like her as much as I did  5  they knew she had “problems”. However, every summer we would   6  sit at each other’s house and watch soap operas and talk about everything we liked.

It was last year when I   7   the problem. I guessed I was just too busy to catch up in high school to realize she   8  someone there for her. Well, she made a new “best friend” and so did I. Then I didn’t know why, but she started cutting herself!

She was diagnosed with clinical depression(抑郁症). I was very  9   at first, but with the late night calls, we still stayed in   10 . I wanted to be there for her since her new best friend   11  deserted her, since people were calling her   12 , and I knew I still   13 her like a sister.

Yesterday she came   14  me and said this, “I never knew what a best friend was   15  you were the only person that would stop me from cutting; the only person that ever made me feel better about myself and my  16 . You don’t know this but I was trying to kill myself one night when you   17  me and I was crying. I   18  you so much, and you didn’t even know you were   19  me.”

We both cried. And I guess a kind of lesson from my life so far is to never   20  your friends.
