In medicine, a stool model refers to a representation or simulation of human feces. It is commonly used for medical education and training purposes. Stool models can be made of various materials and come in different shapes and sizes, representing different types of stool.

A healthy stool is typically firm, moist, and easy to pass. It should have a brown color, although slight variations in color can be normal. Changes in stool color can indicate underlying health conditions, so it is important to pay attention to any unusual or persistent changes in your stool.

Understanding stool models and being aware of the characteristics of a healthy stool can help you monitor your digestive health and detect any potential issues.
