How to Actually Understand Endocrine System (Step-by-Step)

Are you consistently losing points on Endocrine System because of confusing steroid hormones with peptide hormones? If so, you're making the exact same error as 80% of your class.

3. The Fatal Flaw to Avoid

The easiest way to lose points is confusing steroid hormones with peptide hormones. Mark this in your notes right now. When you review your test, specifically check your work for this error.
