Question

CASE STUDIES CELLULAR INJURY AND ADAPTATION 4. These kidneys are from a patient who had atherosclerosis of the right renal artery. The right kidney is the smaller one seen below. The left kidney is larger than normal. What adaptations occurred in each of these kidneys and why? 5. The image below shows the cortex in dark red. Describe the changes in the cortex that 1. Renal infarcts seen on the image below. They are pale and wedge shaped. 2. Define infarct and explain the appearance of the infarct in the kidney 3. What type of necrosis occurred? occurred. Why is the cortex important? A70-216 Cortex is outlined in dark red A70-216 Infarcts shown with outline 6. Below are images from a stroke patient. The damaged tissue is outlined in yellow. What process is occurring in this area? EEA

Answer 1

2) answer :

Infarction is tissue death ( necrosis ) due to inadequate blood supply to the affected area .

it may be caused by artery blockages , rupture , mechanical compression or vaso constriction .

The resulting lesion is referred to as an infarct .

• The images given above showing infarct appearing pale and wedge shaped due to occlusion of renal artery lead to ischemic changes in the kidney .

3)ischemic coagulative necrosis .

4) due to atherosclerosis of right renal artery blocked the blood supply to the right kidney lead to shrinkage of right kiney appeared in above image .

Due to right kidney failure , the left kidney is doing renal functioning and adaptation is made here to maintain normal renal function.

5) answer : dark red colour is due to the haemorrhagic infarct .

Hemorrhagic infarcts commonly caused by occlusion of veins ,with red blood cells entering the area of the infarct ,or an artery occlusion of an organ with collaterates or dual circulation .

6) answer :

The given image shows that the patient is having ischemic stroke .

There is a necrosing of tissue due to decreased or no blood supply to that particular part of the brain.
