“キリンは心臓と頭が２メートル近く離れていおり、そこに血液を巡らせるには強烈な血圧をもつ必要がある。キリンの最高血圧は平均260mmHg、最低血圧が平均160mmHgである。ちなみに人間では最高血圧は平均120mmHg、最低血圧が平均80mmHgである。キリンは水を飲むとき前足を横に広げて頭を下げるが、このとき頭に一気にたくさんの血液が流れてこないように、頚動脈の内壁に一連の血液逆流防止弁が備わっている。” キリン (via suyhnc) (via yellowblog) (via bardiche-side-b) (via nagas-it) (via nagas) (via reretlet) (via saitamanodoruji) (via inumoto) (via yellowblog)
