Answer: EITHER coronary insufficiency due to aortic defect OR front cortex damage due to hitting the desk when she tripped
Step-by-step explanation:
The heart should seem normal until you look at the aortic arch. It may have created discolored patches on the coronal arteries; this is typical, as it usually breaks into a lot of small pieces. If your teacher gave you the damaged brain, the death was due to her tripping and hitting her head on the table. It damaged the frontal lobe's cortex, causing her motor cortex to have edema and that killed her.
