妖媚婷儿 勾引
【写在临了】
许多科普读物,王人说小肠是最长的器官。但其实,果真最长的器官是血管。诚然中学生物讲义并莫得提到血管是器官,但却让咱们知说念了器官的界说:由两种或两种以上不同类型的组织构成,足下一定的功能,承担生物体内一定的使命。
血管其实十足合适这么的界说妖媚婷儿 勾引,组织学上,血管由不同组织类型的齐心层或“被膜”构成:
内膜包括内皮细胞层,以及和相对较薄的撑抓结缔组织层。中模包括中间的肌肉/弹性层,包含平滑肌和不同比例的弹性组织,外膜主如果外层的纤维结缔组织层。诚然神经组织常常在血管中不分解,但用于养息平滑肌功能和养息痛觉。
因此在医学上,血管和胃、肠、膀胱、肾脏等里面具有较大空闲的器官,称为管状器官。
是以,最长的器官并不是小肠,而是血管。
