反刍动物
反刍动物
  简介
  反刍(chú)是指进食经过一段时间以后将半消化的食物返回嘴里再次咀嚼。反刍动物就是有反刍现象的动物,通常是一些草食动物,因为植物的纤维是比较难消化的。
  反刍动物属哺乳纲,偶蹄目,反刍亚目,如骆驼、鹿、长颈鹿、羊驼、羚羊、牛、羊等。由于这类动物都具有复杂的反刍胃,能反刍食物,故称反刍动物
  反刍动物的消化分两个阶段:首先咀嚼原料吞入胃中,经过一段时间以后将半消化的食物反刍再次咀嚼。反刍动物在解剖学的共同特征是均为偶蹄类。
  反刍动物的胃分为四个胃室,分别为瘤胃、网胃、重瓣胃和皱胃。前两个胃室(瘤胃和网胃)将食物和胆汁混合,特别是使用共生细菌将纤维素分解为葡萄糖。然后食物反刍,经缓慢咀嚼以充分混合,进一步分解纤维。然后重新吞咽,经过瘤胃到重瓣胃,进行脱水。然后送到皱胃。最后送入小肠进行吸收。
