Student-Focused Heart Anatomy Article

I need a clear, engaging article that explains why the heart is described as a hollow, muscular organ and how that structure supports its function. The piece should be pitched to high-school and early college students, so scientific accuracy must be paired with approachable language, relatable examples, and concise definitions of any technical terms. Here is what I expect: • 1,200–1,600 words organised under logical sub-headings • Simple line or labelled vector diagrams that reinforce key points (original artwork only) • Credible references formatted in APA or MLA style so teachers can treat the article as a classroom resource You are free to use standard anatomy texts, peer-reviewed journals, and reputable medical websites, but every claim must be backed up by a citation. If you like working in Google Docs or Microsoft Word, that’s fine—just share edit access so I can leave comments. Before we wrap up, I’ll review a draft to confirm tone and depth are on the right track. Once approved, you hand over the final document and image files.
