The red droplets represent fat in the tissue which is typical of fatty degeneration in the liver. By using frozen sections the tissues do not have to be dehydrated throu...)

'''No...)

- 16:56, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2FattyChange5.jpg (This higher-power photomicrograph of the centrilobular area gives the appearance of fatty tissue, as indicated by many empty spaces. Very few normal liver cells can be seen in this slide. A few more normal-appearing hepatocytes are present at the left ...)

- 16:55, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2FattyChange3.jpg (Another low-power photomicrograph illustrates again the pale, washed-out appearance of this tissue. Notice the numerous holes throughout the tissue. There are accumulations of inflammatory cells (arrows) around portal tracts.)

- 16:53, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2FattyChange1.jpg (This gross photograph of liver tissue illustrates the yellowish color of the liver parenchyma. The yellow color indicates high fat content in this tissue. Compare this with the normal dark red color of liver.)
- 16:38, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Calcification2.jpg (This low-power photomicrograph of the patient's lung illustrates large, open alveolar spaces. The pleural surface is the curved surface at the top.)
- 16:36, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Calcification8.jpg (This gross photograph affords a closer view of the same aortic valve. Note the nodularity and thickening of this valve due to fibrosis and dystrophic calcification.)
- 16:36, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Calcification7.jpg (A closer view of this same aortic valve (arrow) illustrates the nodularity and thickening of this valve. This valve would be extremely stiff and almost entirely immobile. This particular example of dystrophic calcification is associated with a degenera...)

Unlike metastatic calcification, dystrophic calcification does not require an increase in serum calcium levels. This is a gross specimen of a heart with dystrophic calcifica...)

- 16:34, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Calcification4.jpg (This high-power photomicrograph of a blood vessel shows calcium deposits in the vascular wall (1) and proteinaceous material (2) (from edema) within some of the alveoli. The smooth muscle in the vessel wall has been almost completely replaced by calciu...)
- 16:33, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Calcification3.jpg (A higher-power photomicrograph shows a blood vessel cut in longitudinal section (1). Several of the alveoli are filled with a pink-staining proteinaceous fluid (2) indicative of pulmonary edema. The alveolar septa and the wall of the blood vessel have ...)
- 16:32, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Calcification1.jpg (This is a gross photograph of the cut section of the patient's lung showing evidence of severe metastatic calcification. The lung tissue has a rough, firm appearance with open airways.)
- 16:12, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Atrophy10.jpg (This gross photograph shows a normal brain (left) and a brain from a geriatric patient (right). Note the decreased size, the narrowed gyri, and the widened sulci of the brain from this octogenarian. What is the cause of atrophy in this case?)
- 16:11, 19 August 2013 Peter Anderson (talk | contribs) uploaded File:IPLab2Atrophy9.jpg (The two kidneys in this slide are from the same patient. One kidney (1) is relatively normal, although increased in size due to compensatory hypertrophy. The other kidney (2) is very small with only rudimentary nodules of renal parenchyma. This kidney ...)

The increased pressure produced hydronephrosis (arrow) in one kidney. What is the cause of atrophy in this case?)

This atherosclerotic narrowing of the renal artery causes reduced blood pressure in the kidney whose artery is affect...)
