Abstract in brief
- Giraffes have a remarkable cardiovascular system with high blood pressure (around 200 mm Hg) to ensure proper blood flow to the brain when their long necks are lifted, which is essential for maintaining cerebral perfusion.
- Their blood vessels, heart, and kidneys are specially adapted both structurally and functionally to handle this extreme blood pressure, preventing damage and ensuring efficient circulation.
- When giraffes stop to drink and then lift their heads, their blood flow and pressures in arteries and veins change significantly, highlighting the unique ways their bodies manage blood pressure during movement.

I've always been fascinated by this animal model, especially regarding CBF regulation. Probably my postdoc supervisor's fault (Niels Secher). Nice read !
Physiology is so AMAZING.
Happy Friday to giraffes and non-giraffes alike!

@verofiamenghi @drmiketodorovic giraffe CV physiology is the best. not just BP, but how they've adapted everything for their height. a nice review here: https://t.co/HWN3CU3CRd
Luckily we have an excellent view of the adaptations that allow giraffes to maintain cerebral perfusion. https://t.co/KlqxPSuegF
@ChrisMinson Indeed! Stroke volume is low, but heart rate is not High, so cardiac output is low. We still struggle with the vonsequences for exercise tolerance and VO2max. And total resistance is very high. Read more here: https://t.co/XejicrT5Sj https://t.co/Vl5km072rD

Ever wonder why giraffes don't get periph edema? Or, if their hearts are large enough to withstand a systemic BP of 200mmHg? How does the kidney withstand this BP? How is the brain circulation protected when giraffe's lower their head to drink?
