在中学讲授肾小体与肾小管的构造时,只用褂图和黑板画进行演示,直观性不够强,所以学生往往得不到明确的印象。我们曾用玻璃制成肾小囊和肾小管形状(图1),制作过程简便,一般玻璃工厂都能代制;再以细小的红色塑料线代毛细血管,缠绕成球形为肾小球,锒进肾小囊内,并继续以网状塑料线缠于肾小管上(图2),同时在部分塑料线上,涂上蓝漆表示静脉,整个模型便制成。经过一段时期试用演示教学,由于是玻璃模型,能明显看到构造情况,学生易于了解,效果很好,特作介绍。
When teaching the structure of renal corpuscles and renal tubules in secondary schools, only demos and chalkboards are used for demonstration. The intuition is not strong enough, so students often do not get a clear impression. We used glass to make the kidney capsule and tubular shape (Figure 1), the production process is simple, general glass factory can be made on behalf of; then a small red plastic thread on behalf of the capillaries, wound into a ball for the glomerulus, hyperthyroidism Inside the renal capsule, it continues to wrap around the renal tubules with a mesh plastic line (Fig. 2). At the same time, a part of the plastic line was painted with blue paint to express the vein. The entire model was made. After a period of trial demonstration teaching, because it is a glass model, can clearly see the structure, the students easy to understand, the effect is very good, special introduction.
