The eyes and sweat glands are among several body parts studies have shown could be at risk, Moskowtiz said.
1. 主干是：The eyes and sweat glands（主） are （系）among several body parts（表） + 定语从句。
2. studies have shown could be at risk 是 “嵌入式” 定语从句，先行词是 parts。嵌入部分是 studies have shown，在studies 之前省略了关系代词 that（that 为定语从句的主语，在嵌入式定语从句中，作主语的关系代词也可省略。
3. 我举一个很简单的这个类型的例句：
He did something （that）she thought was really wrong. 他做了一件她认为确实错误的事。
she thought 是定语从句的嵌入成分，在此情况下，作主语的关系代词 that 也可省略。
如果没有 she thought，那么作从句主语的关系代词不能省略。He did something that was really wrong.

The eyes and sweat glands（主） are（系） among several body parts（表）（which） studies have shown could be at risk（复合定语从句，前面省略了which或that，内含从句studies have shown）, Moskowtiz said.（插入语）
which studies have shown could be at risk 此复合定语从句由which could be at risk, which studies have shown 糅合而成。
