（圖2）以血液循環系統方面來說，牠的心臟必須要抵受比其他動物更高的壓力才能把血液輸送到腦部裡頭。688Please respect copyright.ＰＥＮＡＮＡz33JVwEGHq

同時間，牠亦必須配備完善的機制來調節仰頭吃葉或低頭飲水所帶來的急劇血壓轉變。688Please respect copyright.ＰＥＮＡＮＡNZ0YfiGrLe

若然調節失衡的話，很大機會對其他器官構成威脅及傷害。688Please respect copyright.ＰＥＮＡＮＡVjeIbWDaBz

（圖3）研究發現，長頸鹿的FGFRL1基因出現7道沒能在其他動物(包括人類)尋覓得到的變異。688Please respect copyright.ＰＥＮＡＮＡGUC2ITI80U

有科學家把老鼠的FGFRL1基因轉換成長頸鹿的版本，並為老鼠們注射會引致高血壓的藥物。688Please respect copyright.ＰＥＮＡＮＡTzrkDccpxz

正常老鼠的上下壓在藥物影響下錄得了顯著上升，但擁有長頸鹿版本的老鼠其上下壓並沒有出現顯著的上升。688Please respect copyright.ＰＥＮＡＮＡYJOlxQUa1R

（圖4）最為神奇的是，正常老鼠在藥物的影響下所出現的心肌纖維化徵狀，並沒有出現在長頸鹿版本的老鼠身上。688Please respect copyright.ＰＥＮＡＮＡwRlL8R2N1k

科學家正在嘗試拆解長頸鹿FGFRL1基因版本對心臟等方面所影響的機制，若果能透徹亦剖析整套機制，或許可用作建構抵禦高血壓或其他心臟問題的藥物。688Please respect copyright.ＰＥＮＡＮＡXUb4ktxRrX
