ELI5: Does your body keep taking in water when you get wounded underwater?

Lets say you got shot or something and then fell into a big (or small) body of water. Would a bunch of water fill up in your body causing you to die or?? Sorry if this seems like a stupid question but I've always wondered how dangerous it would be to be underwater with a wound.

No question is stupid. People who say that a question is stupid are the stupid ones themselves.

Anyway, no, water wouldn't fill into your body. Your heart is constantly pumping blood throughout your body, meaning that it's generating pressure to move all of your blood around (this is referred to as one's blood pressure). If you get a major wound, the heart will still continue to pump blood, but since the blood has an opening to escape from, and it's constantly being pumped under pressure, it's going to want to move out of the wound quite quickly to an area of less pressure. This means that instead of water moving into the wound, the wound would instead push water away from it, with blood.
