对成人肝位置的描述，错误的是（）

A.大部分位于右季肋区和腹上区

B.其最高点右侧相当于右锁骨中线与第5肋的交点

C.其最高点左侧相当于左锁骨中线与第5肋间隙的交点

D.下界可超过肋弓下缘，但一般不超过2cm

E.平静呼吸时，肝上、下移动幅度为2～3cm

答案

参考答案：D

解析：肝脏主要位于右季肋区和腹上区，大部分肝为肋弓所覆盖，仅在腹上区、右肋弓间露出并直接接触腹前壁，肝上面则与膈及腹前壁相接。从体表投影看，肝上界在右锁骨中线第5肋骨，右腋中线平第6肋骨处；一般认为，成人肝上界位置正常的情况下，如在肋弓下触及肝脏，则多为病理性肝肿大。肝的位置常随呼吸改变，通常平静呼吸时升降可达2～3cm，站立及吸气时稍下降，仰卧和吸气时则稍升。

If you look into the bag for the one that is left, you will be able to      which stone I picked.” This      tells: Sometimes we can think about things in a      way.
