Answer to Question 1

Perfusion refers to the flow of oxygenated blood through a tissue. Ischemia results when there is too little perfusion, causing an oxygen deficit. Infarction is complete lack of perfusion and a complete lack of oxygen. Necrosis, or tissue death, results from a period of oxygen starvation due to no perfusion.

Answer to Question 2

The combining form phagia means to eat or swallow. The combining form phasia refers to the ability to speak. Contextual clues for dysphagia would be difficulty swallowing, difficulty eating, or a reference to an upper GI tract disorder. Dysphasia is a neurological disorder caused by a brain lesion, not a problem localized to the upper GI tract. Dysphasia often follows a stroke (cerebrovascular accident) or other type of brain injury. Contextual clues for dysphasia might include CVA, stroke, cerebral hemorrhage, or a reference to a neurological disorder.
