1、名师精编优秀教案第三节人体概述学习目标：1.通过阅读文本、观看课件、观察图片，能举例说出组成人体的主要系统以及各系统的主要器官。2.通过分析骨的成分与骨地特性之间的关系，观看课件及相关素材，能举例说出人体各系统的主要功能以及各系统相互联系、相互协调，共同完成生命活动。学习重点：1.识别组成人体的器官和系统，举例说出组成人体的主要器官和系统。2.举例说出人体各系统的主要功能。3.举例说明人体的结构与功能相互统一。学习难点：1.举例说出组成人体的主要器官和系统。2.分析骨的成分与骨的特性之间的关系。课堂导学：一、人体的主要系统和功能：我们现在已经知道，精卵结合能孕育新生命。种族的延续是由生殖系统来
2、完成的。大家还记得男女生殖系统的组成及功能吗？引导学生阅读课本P15-P17人体的主要系统内容，播放课件及相关素材，回答下列问题：1.人体除了生殖系统外，还有哪些系统？组成怎么样？它们的功能是什么？2.观察肌肉和骨骼肌的挂图，回答运动系统有何功能？3.早上到第四节课时，有的同学已饿得饥肠辘辘，肚子咕咕叫，这是哪个系统发生的反应？4.吃葡萄时，葡萄籽被咽了下去，它们是怎样“旅行”的？名师精编优秀教案5.你知道去年上半年，可怕的流行病“非典”是哪个系统的疾病？6.为什么说人体是由各系统组成的统一体？能举例说吗？小结：人体是一个复杂、协调、统一的整体，在各个系统的合作下生命活动能够有序地进行，也使人
3、能够适应环境，在复杂多变的生物圈中生存并得到发展。二、骨的特性与骨的成分:不同系统都有一定的功能，结构与功能是相互统一的，而结构的特性又和结构的成分有关。引导学生阅读课本P17-P18讨论和实验内容，展开讨论及动手操作，播放课件及相关视频，根据长骨的结构与人体长高之间的关系回答下列问题：1.经常参加体育运动为什么能促进青少年身高的增长？2.骨在煅烧时有什么现象产生？最后变成什么颜色？3.把煅烧后的骨放在纸上，用镊子轻轻敲击，有什么现象？说明它含有什么成分？4.鱼骨在稀盐酸中有何变化？说明它含有什么成分？5.鱼骨在浸泡的过程中，你观察到有何种现象发生？6.煅烧的骨容易敲碎，而未锻烧骨不易敲碎？为
4、什么？小结：骨的成分包括无机物和有机物。无机物主要是钙盐，使骨脆硬；有机物主要是蛋白质，使骨柔韧。这两种成分使得骨既有一定的硬度又有一定的弹性。三、总结：1.人体的结构层次。细胞和细胞间质组成了人体的四种基本组织；各种组织有机地联系在一下起，形成各种器官；具有相关功能的器官又组成人体的各系统。2.骨的成分包括无机物和有机物。无机物主要是钙盐，使骨脆硬；有机物文档编码:CY10Z3B9D6R8 HM5R6H1Y2O7 ZL3D3G7M7N6文档编码:CY10Z3B9D6R8 HM5R6H1Y2O7 ZL3D3G7M7N6文档编码:CY10Z3B9D6R8 HM5R6H1Y2O7 ZL3D3G7M
