honeycomb lung

There was one question from Semester 3 exam that I still remember until today. The question asks to describe 'honeycomb lung'. Most of us could not remember learning about 'honeycomb lung'. Apparently the answer was based on 2-3 slides and we need to listen to the explanation given by the lecturer. The question worth 10 marks and I tried my best to answer the question even though I hardly remember anything from the lecture.

My current rotation which is heart and lung reminds me of this unanswered question.

There are many lung diseases that will eventually end up in the same appearance during post-mortem. Honeycomb lung refers to the end stage of various diseases. There is even mnemonic for this term.
Histiocytosis X
Occupational disease (pneumoconiosis, farmer's lung)
NEurofibromatosis
(Y)idiopathic
COllagen vascular disease
Medicines
Bronchiectasis
Sarcoid
This is how honeycomb lung looks like. Pathologist ie the doctors that look cells under the microscope and do post-mortem have a tendency to associate food with dead human tissues.

ape beza urea dan urine?

-sambung soalan cikgu hayad..

hayad said...

urea is excess protein and will be excreted in urine form...

betoi kan doc? :p

urine is the liquid that is excreted by our bladder.

urea on the other hand is the waste product formed from certain biochemical reactions in our body. The main component involved in the formation of urea is protein. So, Hayad is right :)

oowwwhhhh...gitu..faham..faham...

dan cikgu, I did ask my science teacher similar questions.

budak kecik semua tanya soalan sama ek?

hafiz238 said...

urea ni memang dalam bentuk cecair dalam urine (air kencing). Nak tahu lebih lanjut, cuba tanya Cikgu Kimia.

Feel free to ask me any questions and I'll try my best to answer those questions :)
