Could you please help me with my choosing a major?

<p>Hello I'm new here. I am an international student from PRChina, preparing for the college application in the US and planning to enroll in 2012. I'm determined to study natural science, especially biology. But major is a problem. Now I have considered and searched some like biology, biochemistry, medicine, biomedical engineering, human biology, neuroengineering, neuroscience, anatomy, and %#@$#%... but they still seem to be a dreadful mess.
First, I know they have relationships with each other but have difficulty figuring them out (eg. I thought neuroscience should be a subsidiary discipline of human biology, but it does study animal's nervous systems, doesn't it? So it's not merely human biology...);
Second, I do not really know what a biomedical engineering student will study in college, and what a biomedical engineer will do after graduation.
I appreciate every help you offer.</p>

<p>My ideal major and career:
1. deal with nature, animal or human body; never think of botany (I always hate remembering the structure of a stem, a flower, a seed and a leaf).
2. do some research, fieldwork or in labs.</p>

<p>Thank you again!</p>

<p>anyone? maybe it’s night in US?</p>

<p>Biology would be the main science affiliated with nature, so anything affiliated with that (i.e. bioengineering, bio-chemical engineering) would have to do with nature as well.</p>
