vasodilatation and increased permeability lasting for several days in an area of inflammation indicatewhich of the following
1)thrombosis
2)release of histamine
3)hageman factor activation
4)formation of granulation tissue
5)endothelial cell damage and disruption

spontaneous bleeding seen in acute leukemia is because of
1)infections
2)thrombocytopenia
3)vascular fragility
4)hypoprothombinemia

complication of pepetic ulcer that account for majority of death
1)bleeding
2)perforation
3)obstruction
4)malignancy

immunologic injury that involves activatin of a complement as an important event in producing damage to the tissues is seen in
1)immune complex mediated hypersensitivity
2)antibody_dependent cell mediated cytotoxicity

to determine bacteriological purity of meteropolitan water supplies ,sanitation engineers routinely check for
1)e coli
2)salmonella typhi
3)giardia lamba
4)entamoeba histolytica
4)shigella dysenteriae

which of the following is classified as an endogenous infection

2)dysentry
3)gas gangrene

hope this helps...pls post the right ans if im wrong...

Most common cause for papillary muscle hypertrophy ??!

inhalation of mycobacterium cause
a.attach to pnemocytes
b.phogoctytosis of mycobac
c.phoycytosis after humoral activation
d.growth of normal flora along with myco

hydrolyis of what causes reduce free energy
ADP
cAMP
creatine phosphate
GTP
 
mouthwash contains 0.05%of fluoride what is the value in ppm
5
50
500
5000
how do u calculate this

not very confident though!!!
 
blood velocity is lowest in which of the following vessels
vein
venule
artery
arteriole
cappilary
 
answer is veins...confident.

1) First approach

Simple equation to calculate Velocity

Velocity(flow) is Inversely proportional to Cross sectional area..

Cross sectional area(not to be confused with radius)
Greatest - capillaries
Lowest - Aorta
Highest to lowest cross sectional area - Capillaries>arterioles(venules)>Arteries(veins)>Aorta

So lowest velocity is in Capillaries and Highest in Aorta.

Put this facts into above equation...If still in doubt refer simple diagram in kaplan medical usmle physio pg 78.

2) Second approach is logic..If u beleive Oxygen and co2 are exchanged at capillary level with varios organs/tissues and blood vessel....Then it has to hav the slowest velocity to aid that...How else would the exchange take place?

Plz feel free to correct..

:thumbup:

Velocity is lowest in capillaries
Viscosity is highest in capillaries (also related to temperature and hematocrit)
Blood pressure is lowest in veins.
