Academic analysis:

Sweating and urination are ways in which the human body produces and excretes metabolic waste, and are closely related to students' lives. The content of this section can be analyzed and studied based on students' own examples.

During teaching, attention should be paid to guiding students to pay attention to water and salt balance and maintain their own health.

The importance of excretion to human life activities;

Route of excretion.
