Step 1: Understanding the Concept:
This matching question tests the understanding of standard medical and pathological terminology used to describe postmortem changes, lesions, and clinical signs in animals.
Step 2: Detailed Explanation:
Let us define each term to find its correct match:
- Livor mortis (A): This is a postmortem change characterized by the settling of blood in the dependent parts of the body due to gravity, causing a reddish-blue discoloration of the tissues. This process is also known as Postmortem hypostasis. This matches with (III).
- Pyosalpinx (B): This is a pathological condition characterized by the accumulation of pus in the fallopian tube or oviduct, usually resulting from an untreated infection. This matches with (I).
- Hematemesis (C): This is a clinical sign characterized by the vomiting of blood, which may appear bright red or dark brown (resembling coffee grounds) due to gastric acid exposure. This matches with (II).
- Hemoptysis (D): This is a clinical sign characterized by the coughing up of blood or blood-stained sputum from the respiratory tract. This matches with (IV).
Combining these individual linkages, the matching sequence is (A) - (III), (B) - (I), (C) - (II), (D) - (IV).
Step 3: Final Answer:
The matching sequence is represented by option (C).
