人体静脉的意义和功能 静脉负责将血液从各个器官输送回心脏，而动脉则将富含氧气和营养物质的血液从心脏输送到身体的各个部位。 很多静脉，尤其是手臂和腿部的静脉，都有单向阀。 这些阀门由两个边缘相接的瓣膜组成。 顺着心脏方向流动的血液会使这些瓣膜打开，就像一对只朝一个方向移动的旋转门。 如果重力或肌肉收缩试图逆转血流，或者血液试图在静脉内积聚，这些瓣膜就会自动关闭，防止血液倒流。 因此，这些瓣膜有助于血液回流到心脏，在血液流向心脏时打开，在可能出现逆流时关闭。 (https://veinscarolina.com/a-discussion-about-venous-reflux-with-vein-specialist-dr-david-draughn/) 人体深静脉及其重要作用 位于身体深处的静
