科学家认为猴子的早死与垂直运动有关。研究认为,由于垂直运动,所有脏器的位置都不同程度地升高了。心脏要推动血液循环,除了要克服血液在血管内运行时产生的磨擦力外,还要克服血液重力,增加了“泵”血的难度,使心脏不得不加倍消耗能量,而促使其早衰。另一方面,直立行走时,下肢属主要活动器官,血液会更多地分配到下肢,而心脏和心脏以上的器官血液供应相对减少,大脑供血更是不足。因此,科学家认为,人类
Scientists believe that premature death in monkeys is related to vertical movement. The study concluded that due to vertical movement, the position of all organs increased to varying degrees. Heart to promote blood circulation, in addition to overcome the blood friction in the blood vessels within the operation, but also to overcome the blood gravity, increase the “pump” blood difficult, so the heart had to double the energy consumption, and promote its premature aging. On the other hand, when standing upright, the lower extremity, which is the main organ of activity, distributes more blood to the lower extremities, while the blood supply to organs above the heart and heart is relatively reduced. Therefore, scientists think that humans
