Throughout the years we have learned a lot about how our bodies function and why they do the things they do, scientists have been VERY wrong in the past and some medical procedures have been very unsuccessful, and looking back we are all collectively like wow we were so dumb. But how do we know for sure we are correct now? Like how did we learn that the ovaries producs eggs that become fertilized by sperms and how on earth was this discovered and tested? How do we know its our thyroid that regulates hormones that effect other parts of the body?

It was illegal for a very long time to study dead bodies, so we had to make do with what we could see on the outside. For a century or more, doctors followed a text from a physician named Galen, who was really wrong but was so respected that nobody wanted to go against the teachings.
Even when dead bodies were illegally examined, you can’t see the body’s workings in motion. Even then, we didn’t have the right diagnostic tools like a microscope until pretty recently.
With the invention of antibiotics, imaging, and sedation, it’s much easier to see the inside of a body and how it works while keeping the body alive. We are still learning things that disprove old beliefs.
