人体胸廓的前后、左右和上下径有节律地扩大与缩小,完成呼吸运动,主要是肋间肌和隔肌活动的结果。为表示两者之间的关系,我们将“肋骨运动和呼吸运动的关系”演示模型作了改进,设计制作了呼吸运动演示模型,增强了教学的直观性,效果很好。 The front and rear, left and right, and upper and lower diameters of the human thorax are rhythmically expanded and contracted to complete respiratory movements, mainly as a result of intercostal and diaphragmatic activities. In order to show the relationship between the two, we have improved the demonstration model of “the relationship between ribs and respiratory movements”, designed and produced a demonstration model of respiratory movements, enhanced the intuitiveness of teaching, and achieved good results.
