actually this question is absurd
considereing all choices, i would go for stomach.(pancreas exclusion being a gland) (me between b and e)

stomach has high cell turn over and gets replinished too ,we sometimes take smoked food too .......

what is everyones opinion on this question?

i found this online so voted against pancreas,i am not sure of the answer but

"Smoking has been identified as the single most significant independent risk factor associated with familial pancreatic carcinoma.

just for information i would lke to add the following----

RENOVASCULAR HYPERTENSION -----is a secondary form of high blood pressure caused by a narrowing of the renal artery.
--Renal hypertension is the most common form of secondary hypertension
--There are two forms of renovascular hypertension--
1- atherosclerotic renovascular hypertension ---deposits narrow the artery, disrupting blood flow seen with men .
2-Renovascular hypertension caused by fibromuscular dysplasia In fibromuscular dysplasia, cells from the artery wall overgrow and cause a narrowing of the artery channel.seen with women

Narrowing of the renal artery reduces the flow of blood to the kidney,the kidney produces the protein renin. Renin is released into the blood stream. Through a series of steps, renin is converted into an enzyme that causes sodium (salt) retention and constriction of the arterioles. In addition to atherosclerotic and fibromuscular dysplasia, narrowing of the renal artery can be caused by compression from an injury or tumor, or by blood clots.

1- osteosarcoma
2-Prevotella intermedia is an obligatory anaerobe, black-pigmented, gram-negative rod that is frequently associated with periodontal disease: adult periodontitis, acute necrotizing ulcerative gingivitis, and pregnancy gingivitis. This organism is also involved in extraoral infections such as nasopharyngeal infection and intra-abdominal infection .It is found in plaque .

i guess the answer here is ----d-immediately b4 periodontal disease.
correct me if i am wrong.

ans -puberty

hey friend i cant give u the content which has copyright issues , search for it and you find it .
strept salivarius dominates(98%) -0 to 6 months
then mutants and sanguis in 6to 9months depending on tooth eruption because it needs gingival crevice
infants oral flora is similar to the mother .

bacteriodes and spirochetes comes late in life in puberty (teenage).prevotella was considered a subclass of bacteriodes melaninogenicus ,now known as prevotella intermedia .

I double checked ,prevotella is seen in eop(early onset peridontitis) and adult peridodontitis ,true , ,if we want to isolate it u have to go to a pathological site in the body , just to prove these r normal habitats in mucosal surface i am quoting this from a reputed site .


Anaerobes that are part of the indigenous flora of the oral cavity can be recovered from various infections adjacent to that area, such as infectious cervical lymphadenitis,subcutaneous abscesses and infected burns in proximity to the oral cavity; infected human and animal bites paronychia; tonsillar and retropharyngeal abscesses chronic sinus infection. chronic otitis media; periodontal abscess ,infectious thyroiditis. aspiration pneumonia,empyema and bacteremia associated with one of the above infections.The predominant anaerobes recovered from these infections are species of anaerobic gram-negative bacilli (including pigmented Prevotella and Porphyromonas , Prevotella oralis and other Prevotella species, and Fusobacterium ) and gram-positive anaerobic cocci ( Peptostreptococcus species), which are all part of the normal flora of the mucosal surfaces of the oral, pharyngeal, and sinus cavities .

as u said " if it is immediately before periodontal disease " ,imagine just before periodontal patho, prevotella comes and camps and cause this!!,where does prevotella come from then?

so u decide which is good for you!!!

as far as i know stomach has the highest turn over rate (replinishing capacity)

so i thought it wont be , well stomach and urinary bladder seems so narrow i would go for stomach .


another doubt which cause the highest mortality in peptic ulcer ?
