Reply to comment by Hagenaar in How do giraffes breathe? by NimishApte

Apparently, a giraffes BP is 280/180mmHg

Regarding the headrush, they don't

Edit:

Giraffe's have basically a vascular sponge in their brain, which dampens BP spikes when moving the head. Also, their arteries have valves as well.

Right. But where are we measuring that bp? I'd assume body as there's no need to have that much pressure at the brain.

At heart level as always. At head level it's apparently at 75mmHg while a humans at headlevel being 60mmHg

I also have a sponge in my brain. But that's another story. I dampen tictock videos and ignore all of them.
