Respiratory and Urinary System of Avian-Video课程教案、知识点、字幕

各位同学 大家好

我是来自中国农业大学的曹静

今天我们来学习家禽的解剖特征

家禽的呼吸系统

由鼻 咽 喉 气管 鸣管(鸣泡) 支气管

肺和气囊等器官组成

家禽的鼻腔狭窄

鼻孔位于上喙基部

两侧鼻腔由鼻中隔所隔开

鼻中隔大部分由软骨所构成

鼻腺位于鼻腔后部及眼球上方

输出管沿鼻骨内面向前 开口于鼻前庭

水禽的鼻腺相对较发达

特别是在海洋生活的禽类

鼻腺有分泌盐分的作用 也称为盐腺

气管为喉的直接延续

由软骨环作为支架 与食管伴行

位于颈的腹侧 在颈的下半部偏至右侧

进入胸腔后 在心基的背侧分为两支

分叉形成鸣管

鸣管是禽的发声器官

位于胸腔入口后方

鸣管由气管和支气管的软骨环

以及鸣骨构成支架

鸣骨呈楔形 位于支气管杈的顶壁

将鸣腔一分为二

在支架上具有两对弹性薄膜

为内 外鸣膜

二者之间形成一狭缝

当禽呼气时 空气震动鸣膜而发声

公鸭的鸣管由软骨环做支架

在左侧形成一膨大的骨质鸣泡

家禽的肺呈鲜红色

左右两肺略呈扁平的四边形 不分叶

位于胸腔背侧部

两肺的背面嵌入肋间

表面有较深的肋压迹

腹侧面覆以膜质的肺膈

家禽的支气管

在肺内形成相互连通的管道

而不形成支气管树

气囊是家禽所特有的器官

是支气管黏膜的肺在外面的延伸

囊壁较薄 气囊共有9个

1个锁骨间气囊 1对颈气囊

1对胸前气囊 1对胸后气囊和1对腹气囊

颈气囊 锁骨间气囊和胸前气囊

共同组成了前气囊

胸后气囊和腹气囊共同组成后气囊

这张图片是我们在解剖鸡时

所观察到的腹气囊

它晶莹剔透

气囊壁是由一层透明的结缔组织膜所构成

血液供应相对比较少

因此 它不具有气体交换的作用

那么气囊的功能主要是做为贮气装置

同时参与肺的呼吸

那么还对于机体的体温调节 减轻体重

调节重心 共鸣也起到共同的作用

家禽的泌尿系统包括肾和输尿管

没有膀胱

肾较大 狭长

位于腰荐骨两旁和髂骨的骨窝内

分前 中 后三部

没有脂肪囊 也没有肾纤维膜

家禽的肾没有肾门

肾的血管和输尿管直接从肾表面进出

输尿管为较直而细的管道

从每一个肾的中部走出

沿肾的腹侧面向后伸延

开口于泄殖道顶壁的两侧

而且家禽的肾也没有肾盂和肾盏
