How do individual cells work together to form organs? For example, how does a heart cell know it’s a heart cell and know what to do?

Someone will chime in with a better answer than this but in the meantime
Every cell in your body (besides gamete’s if you found those) has your ENTIRE DNA in them. However, when they need to produce structures or cell specific things they only “read” the section of the DNA that pertains to them.
Basically you can think of your DNA as a book that contains all instructions for you that every cell has but they only read the chapter relevant to them.
Now I’m sure there’s a method to how they read just their segment of the DNA but I don’t know that and someone smarter than me will have to explain it. I don’t know how they know to only read **that** chapter.
