**Question:** Last organ to be dissected during autopsy in asphyxial death is

A. Brain
B. Heart
C. Lungs
D. Liver

**Core Concept:**
Autopsy is a post-mortem examination of a body to determine the cause of death or identify any underlying medical conditions. In asphyxial death, the primary cause is respiratory failure due to lack of oxygen. The sequence of organ involvement during asphyxia involves the respiratory system first, followed by the cardiovascular system, and finally the central nervous system.

**Why the Correct Answer is Right:**
In asphyxial death, the primary cause is respiratory failure. As the respiratory system is the first to be affected, it makes sense that the last organ to be dissected would be the most distal organ in the respiratory pathway. In this case, the correct answer is **D. Liver**, which is the most distal organ in the respiratory pathway. The liver is not directly involved in respiratory function.

**Why Each Wrong Option is Incorrect:**

A. **Brain (Cerebrum):** Although the brain is involved in respiratory control, it is not the last organ to be dissected during autopsy in asphyxial death. The brain is more directly linked to the respiratory system than the liver, which makes option C incorrect.

B. **Heart (Cardiovascular System):** Although the cardiovascular system is involved in asphyxial death, the heart is not the last organ to be dissected during autopsy. The heart is more directly linked to the respiratory system than the liver, making option B incorrect.

C. **Lungs (Respiratory System):** The lungs are the primary site of injury in asphyxial death and are the first organs affected. Therefore, they are not the last organ to be dissected during autopsy. This makes option C incorrect.

**Clinical Pearl:**
During autopsy, the order of examination should be followed according to the sequence of organ involvement in asphyxial death. This helps in obtaining a more accurate understanding of the cause of death and the sequence of organ involvement.

**Correct Answer Line:**
Correct Answer: D. Liver
