Final answer:
Sammi's model accurately includes the major organs and depicts the process of nutrient absorption, but it could be improved by using materials that more closely resemble the properties of the digestive tract and representing the complexity of the capillaries.
Step-by-step explanation:
Sammi's model includes the major organs responsible for circulating blood as well as the major organs involved in digestion. This is a strength of her model because it accurately represents the interaction between the digestive and circulatory systems in the human body.
The model also depicts the process of nutrient absorption in a visual way, which is another strength. This helps to explain how nutrients are absorbed from the small intestine into the circulatory system.
However, the model does have some weaknesses. Cardboard and the tissue of the digestive tract have different properties, so using cardboard to represent the digestive tract may not accurately represent the actual interaction. Additionally, the model only includes one system (the digestive system) and does not show the complexity of the capillaries in the circulatory system, which is another weakness.
Overall, Sammi's model accurately includes the major organs and depicts the process of nutrient absorption, but it could be improved by using materials that more closely resemble the properties of the digestive tract and representing the complexity of the capillaries.
