WordPress show only one category, excerpts only, on a page

I have a page set up to show only posts from one category, which I’m calling using the php query_posts function. How to I make it so that the posts are displayed as excerpts only, not as full articles?

Here’s the code I’m using on the page:

<?php query_posts('category_name=news&showposts=10'); ?>
<?php while (have_posts()) : the_post(); ?>
<?php endwhile;?>

*incorporated WordPresses excerpt function:

<?php query_posts('category_name=news&showposts=10'); ?>
<?php while (have_posts()) : the_post(); ?>
    <?php the_excerpt(); ?>
<?php endwhile;?>

Now I’m seeing first a list of the excerpts that I want followed by a repeat of the posts in the entirety…
