During an autopsy, the lungs, liver, and brain are examined for signs of disease or damage. Common lung findings include congestion, inflammation, and fluid in the air sacs, which can result from infections, heart failure, or toxins. The liver is checked for inflammation, fatty liver disease, cirrhosis, and cancer from factors like viruses, alcohol, or medications. The brain is assessed for swelling, tissue death from lack of blood flow, and bleeding, as well as conditions such as Alzheimer's, Parkinson's, and multiple sclerosis that cause specific pathological changes.

2. • The Lungs
• During an autopsy, the lungs are carefully examined for any
pathological changes. Common findings include congestion,
inflammation and fluid accumulation in the air sacs. These changes
can be caused by a variety of factors, such as infections, heart failure,
or exposure to toxic substances.

3. • The Liver
• During an autopsy, the liver is examined for any signs of disease or damage.
Some common pathological changes that may be observed in the liver are
• Inflammation
• fatty liver disease
• Cirrhosis
• liver cancer.
These changes can be caused by a variety of factors, including viral infections,
alcohol abuse, and certain medications. Inflammation of the liver, also known as
hepatitis, can be caused by viruses such as hepatitis A, B, and C. Fatty liver
disease occurs when there is an accumulation of fat in the liver cells, which can
lead to inflammation and scarring. Cirrhosis is a condition in which the liver
becomes scarred and unable to function properly. Liver cancer can also develop
as a result of chronic liver disease or other factors.

4. • The Brain
During an autopsy, the brain is carefully examined for any signs of
disease or injury. Common pathological changes that may be observed
include
1. cerebral edema is the swelling of the brain due to excess fluid
accumulation.
2. cerebral infarction which is the death of brain tissue caused by a lack
of blood flow.
3. Hemorrhage or bleeding within the brain.
In addition to these changes, there are also a variety of diseases and
conditions that can affect the brain, such as Alzheimer's disease,
Parkinson's disease, and multiple sclerosis. These conditions are
characterized by specific pathological changes that can be identified
during an autopsy. For example, Alzheimer's disease is associated with
the accumulation of beta-amyloid plaques and neurofibrillary tangles in
the brain, while Parkinson's disease is characterized by the loss of
dopamine-producing neurons in the substantia nigra region of the brain.
