答案

(1)导管 激素 毛细血管 血液循环 内分泌 (2)甲状腺 甲状腺激素可以调节人体的新陈代谢,促进生长发育(3)6卵巢 雌性 (4)5胰岛

题目分析:(1)人体内有许多腺体,其中有些腺体没有导管,它们的分泌物直接进入腺体内的毛细血管,并随着血液循环输送到全身各处,这类腺体叫做内分泌腺.如1垂体、2甲状腺、3胸腺、5胰岛、4肾上腺、6性腺(男性的是睾丸和女性的是卵巢)等.有些腺体如汗腺、唾液腺、肝脏等,它们的分泌物可以通过导管排出去,这类腺体叫做外分泌腺。(2)2甲状腺能分泌甲状腺激素,可以调节人体的新陈代谢,促进生长发育。(3)6是女性的卵巢,能产生卵细胞和分泌雌性激素,雌性激素能维持女性的第二性征,使身体发生很大的变化,进入青春期后的中学生,身体发生了明显变化,女学生的变化主要是由6卵巢分泌的雌性激素调节的结果。(4)多饮、多尿、多食,且日渐消瘦、四肢无力,是糖尿病的症状,是5胰岛分泌的胰岛素不足引起的,胰岛素能调节糖的代谢,促进血糖合成糖元,降低血糖的浓度。
