Nephrons - The First Time I Loved Biology

I don't love piss play but I love the kidneys. They were the first time I fell in love with biology. Kidney beans are kind of like upping your rib cage weirdly. And you know one time he got in grade school hit by a football really hard playing because he was like trying to be masked and I peed blood for a full time. Oh my god you got red pee because that didn't tell anyone. But it's super like I just think that's why I love them even to start like they're filtering our blood that's so freaking cool.
