Nephron model

Abstract

The invention relates to a nephron model which comprises a body, wherein the body is provided with a filter device and a reabsorption device; the filter device is mounted above the reabsorption device and comprises a filter inlet, a filter part and a filter outlet, and two ends of the filter part are communicated with the filter inlet and the filter outlet respectively; the reabsorption device comprises a receiving port, an absorption part and a discharging port, and two ends of the absorption part are communicated with the receiving port and the discharging port respectively; the filter outlet is communicated with the receiving port; the filter part comprises a plurality of through pipes and flow guide grooves of the through pipes; the absorption part comprises at least one conduit and a plurality of through holes formed in the bottom of the conduit. The nephron model can simulate the filter function of glomerulus and the reabsorption function of kidney tubules, the whole process of the nephron functions can be shown vividly in a class teaching process, and a student can know and master the nephron structure and functions.

Description

technical field [0001] The invention relates to the field of medical teaching instruments, in particular to a nephron model. Background technique [0002] In recent years, in teaching classrooms, especially in the section "Discharge of waste from the human body" in the second volume of junior high school biology, the structure and function of the nephron, which is an important and difficult knowledge, is often explained using multimedia courseware or inoperable models , but the teaching effect is often not very ideal, and students say that they have not mastered it deeply enough. [0003] The traditional nephron model is based on the principle of anatomy to make the kidney structure model. The structure is simple and rigid, and it only shows the kidney structure collectively, which fails to allow students to deeply understand the operation. Contents of the invention [0004] Based on this, it is necessary to provide a nephron model for the problems of inoperable exercises...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a nephron model for the problems of inoperable exercises for students, unsatisfactory classroom teaching and single structure, which also solves how to set up the filter inlet, filter part, filter outlet, receiving port, Outlets, several through pipes and their diversion grooves, at least one conduit and several through holes arranged at the bottom of the conduit, and technical issues of how these structures are connected
