"We are gonna use REAL Human skin " Me:Ah yes my favourite

Summary: So a tatoo isn't just some drawing on your skin, all your cells (macrophages/white blood cells) in your skin are actually constantly working to contain the ink on the same spot because the cells can't get rid of it but don't want it to spread either.

I remember a cadaver I had the opportunity learn from years ago. They had multiple tattoos on their body. Remember our TA pulling the skin back so we could see the tattoo on dermis. What we didn't expect was seeing evidence of the tattoo ink embedded in the muscle layer. It wasn't all of the tattoo but you could definitely make out the basic shape of the tattoo.

I served in the US Navy from 1964-1968 but never got a single tattoo. As a Hospital Corpsman (Medic) I learned a bit about what injecting ink into you skin can do and avoided them, even when I was a bit drunk.

I swear this guy just explained more to me than teachers ever did about the human anatomy

Would love to see what happens when you get stretch marks.

This video answered so many questions and explained very clearly! Could you do a video on how laser removes the tattoo? That would be interesting!

This a very educational video. I've been tattooing for 27 years now and I found it awesome.

My mother donated her body to science out of nowhere. I’m watching these to try to come to terms and get more comfortable with it.

Why can't Life Science at school be like this though😭so practical and easy to understand

I liked this video and have seen others that you've done. I'm a professor in a school of nursing, and I appreciate how you can explain A&P in a way that makes sense to a lay person - also appreciate the cadavers. One thing I was hoping you would touch on in this one is the heavy metals that are in all tattoo inks - each color has a predominance of a specific heavy metal. They have been linked to increased sensitivity in general in people, including joint replacements when they become necessary - that good ol' well-meaning inflammatory process.

me waiting for him to actually tattoo the skin

Whenever I see body parts that belonged to an actual person, I always ask myself "how did they die? Why did they choose to donate their body? What was their life like? What kind of person were they?"

Your videos are all so informative and interesting. You do an amazing job explaining things in an engaging, easy-to-understand way. I’m not in the medical field; I just like learning new things. Thank you for taking the time to put this content out there.

The way he explains things is so cool. I just got my first tattoos and now I'm scared xd but i did learn a lot here. Love this channel.

"Don't worry, I can handle criticism. I have pretty thick skin." The skin in question: 14:35

This guy seems so happy and passionate about educating people! His demeanor makes me want to keep watching

You are a fabulous, natural teacher. I always learn something when I watch your videos

My tattoos have blown out and I always felt it was bc of the locations where my skin is thinner. Now I know, another great video. Honestly, I can't get enough of this channel atm!!
