正常的脾脏隐藏在左侧第9、10及11肋之后,它必须至少增大50％始能摸到。 脾的正常功能在胎儿和新生儿中是造血,但到成人则无此作用。脾的红髓为红细胞和血小板的破坏场所,也是去除豪威尔氏体和成熟红细胞核的场所。白髓将淋巴细胞从循环中滤出,并可能具有重要的免疫功能。成年人行脾切除后除对肺炎球菌的感染增加易感性外,尚未观察到其它不良后果。 After the normal spleen is hidden behind the 9th, 10th and 11th ribs on the left, it must be increased by at least 50% before it can be touched. The normal function of the spleen is hematopoietic in fetuses and newborns, but not in adults. Spleen red pulp for the destruction of red blood cells and platelets, but also to remove Howell’s body and mature erythrocyte nucleus of the place. White pulp filters out lymphocytes from the circulation and may have important immune functions. In spite of increased susceptibility to pneumococcal infection in adults after splenectomy, no other adverse consequences have been observed.
