This brings to mind a memory from my childhood. My dad’s a fisherman, and when I was little I’d sometime go on really short trips with him on his longliner. I was catching cod, with a single line. I’d have a cod on the hook on one side of the boat, then I’d have to haul the line over to the other side, then go back and haul it to the other side. Over and over, until the fish was out.
When the cod was caught, it was quickly filleted and put on ice. The organs would be removed and, usually, thrown overboard for the seagulls to eat. I was just taking everything in when I saw something sliding along the deck. It was moving, on its own! Upon closer inspection, I realized it was a cod’s heart, still beating strong. I was not disgusted, but thoroughly intrigued.
A fish’s heart is the simplest of vertebrate hearts. It has two chambers - one atrium, and one ventricle. In comparison, our heart is four-chambered. Blood enters the atrium, where it flows into the muscular ventricle. The ventricle pumps it through a very elastic section called the conus. After the conus, it exits the aorta and travels through the body, then through the gills where it’s oxygenated again. A fish’s blood travels in a single circuit.
My heart will go onnnnnnn
Agh. The future stresses me out!
I’m going into something biology-related, that’s for sure.
But while I like the observational aspect of biology, I think I’d enjoy the experimental side, too.
I’ve always liked engineering and the adoption of patterns or chemicals found in living things to create new technology or improve existing technology.
There’s so much offered in university that it’s really hard to decide what way to head.
It’s like someone removed your fetters and told you to run along one of any of the hundreds of equally beautiful paths ahead of you.
What to do? If you’re a person who finally decided what to specialize in, please tell me how you came to what you did. Please?
