Time for an abnormal section 001(1) Click the link Links to an external site. to activate your virtual microscopy page. You should see your two normal liver sections, which you can use for comparison. Below them, click on section 001(1) and examine the section. Below are some fragments of text that, together, make up a description for this section. Indicate if you think each are architecture, constituent components, non-constituent components, or interpretation: 1. The section shows a piece of liver. Architecture 2. Central veins, and portal triads can be seen clearly in normal lobular arrangement Architecture 3. The portal triads consist of a bile duct, portal vein and hepatic arteriole though at times these features are indistinct Constituent components 4. The central veins are clearly visible Constituent components 5. The hepatic cords and sinusoids are not clear Constituent components 6. There is widespread vacuolation of the cytoplasm of the hepatocytes. This ranges from many small vacuoles within an eosinophilic cytoplasm in hepatocytes near the central vein; to large vacuoles completely filling and distending the cytoplasm and pushing the small dense nucleus to the side in hepatocytes closer to the portal triads. Constituent components 7. Within the connective tissue of the portal triads there are many individual cells with a small dense round basophilic nucleus and little cytoplasm (lymphocytes). Non-constituent components 8. Widespread periportal hepatic lipidosis Interpretation 9. Reversible cell injury and mild periportal inflammation Interpretation

Step-by-Step Analysis
We will evaluate each statement and decide which category best fits for that item, using the given answer keys as a guide while explaining why that category is appropriate or inappropriate.
1. 'The section shows a piece of liver.' — Architecture
This describes a description of the overall structure visible in the section, not a specific cellular part or feature. Architecture refers to the general arrangement or framework of the tissue (e.g., liver as an organ, lobular layout, overall tissue plan). Treating this as architecture is appropriate because it sets the context of what is being viewed rather than detailing a particular component.
2. 'Central veins, and portal triads can be seen clearly in normal lobular arrangement' — Architecture
Here the statement emphasizes the presence of major organizational features (central veins and portal triads......Login to view full explanationLog in for full answers

The best place to view the primary pathological process in action is generally on the edge of the lesion- in the middle it will often be confused by secondary changes, such as necrosis and haemorrhage. Normal lung to left of image. On right note infiltration of alveolar spaces by cells. Note different sizes and shapes of cells (pleiomorphism), some binucleated cells, some joined and others not (degrees of de-differentiation) Name the labels for the section below: A: Cells within alveolar spaces , B: Cells forming a line , C: Alveolar wall .
In one area, there is a raised, dome-like lesion. The mass is well demarcated and doesn’t extend into the subcutis. The lesion is covered by a thin layer of epidermis, which has become ulcerated and shows superficial infiltration by individual round cells with a lobulated nucleus (neutrophils) and plump spindle-shaped mesenchymal cells (likely fibroblasts and vascular endothelial cells in repair). Label the features: A: Collagen Fibres , B: Neutrophils , C: Mesenchymal cells (fibroblasts or endothelial cells)
The remainder of the section appears more dense. Here some areas are highly cellular, while others appear as amorphous pink material with some nuclear debris. There is also marked distension of blood vessels. Name the labels below: A: Highly cellular area , B: Nuclear fragments/ debris , C: Amorphous pink material
