Answer 1

ammonia accumulation

Step-by-step explanation:

Answer 2

Coagulative necrosis

Step-by-step explanation:

• When cell death occurs due to ischemia or infarction then this is termed as Coagulative necrosis.
• During this type of necrosis, cell death occurs in a localized area due to lack of oxygen and other nutrients.
• When a two year old swallows watch batteries then these batteries becomes trapped in the digestive system and inside the digestive tract , the positive and negative terminals of the battery gets bridged by the mucosa leading to the production of the electrical current and increase in the pH of the mucosa.
• All these condition leads to coagulative necrosis due to which the kidney gets affected and heart failure occurs .
