I am wondering if the biometric information collected by Apple's Health app stays local on my iPhone, or if it's being sent to Apple?

Unless you choose to backup your data to iCloud, none of your data will be sent to Apple. Even if you do choose to backup your data to iCloud, that data is encrypted - meaning only you can access it.
Apple’s privacy policy is here and you can request Apple send you all the data they have and inspect the health data yourself to know how / when / what was collected based on how you set up your accounts and sync options combined with how iOS is programmed.
However, you also decide what 3rd party apps, if any, you want to have access to your health data. These can be set via the Health app directly or via Settings > Privacy > Health. So make sure you check their privacy policy if this concerns you!
To quote Apple directly:

In a nutshell, only you (or anyone who knows your passcode or has a fingerprint set on your iPhone) have control of your health data.
