为了使学生更好地理解尿的形成过程。可就地取材作一套尿的形成简易装置。具体方法是: 做一块演示板,大小如下图所示。在木板中央挖一小孔(能放入漏斗上口一部分)。将肾小囊(漏斗上口)和肾小管(漏斗颈)用细铁丝固定在木板上。另一分液漏斗固定在左上角,其中装红墨水(示血液)。分液漏斗下连入球小动脉(胶管)。肾小球(输液管弯曲而成)一端与入球小动脉相连,另一端与出球小动脉相连。
In order to enable students to better understand the urine formation process. Local materials can be used as a simple device for forming urine. The specific method is: Make a demo board, the size is as shown in the figure below. Drill a small hole in the center of the board (can be placed in the upper part of the funnel). Kidney sac (upper funnel) and renal tubule (funnel neck) were fixed on the wood with a thin wire. Another separatory funnel is fixed in the upper left corner with red ink (shown blood). Under the separatory funnel was connected to the arterioles (pipes). The glomerulus (the infusion tube is bent) is connected at one end to the afferent arteriole and at the other end to the arteriole.
