Ph at the arterial end of a capillary is 32 mm hg, and ph at the venous end is 24 mmhg. the plasma colloid osmotic pressure across the entire capillary bed is 25mm hg. across the entire length of the of the capillary, which of the following will most likely occur?

net filtration

net absorption

net filtration and net absorption

neither filtration nor absorption

Net Filtration and Net Absorption

Explanation:

Given:

Pressure head at the arterial end of a capillary, ΔP₁ = 32 mm Hg

Pressure head at the venous end, ΔP₂ = 24 mm Hg.

plasma colloid osmotic pressure across the entire capillary bed, Δπ = 25mm Hg

Now,

At the arterial end

Net filtration pressure =  ΔP₁ - Δπ = 32 - 25 = 7 mm Hg

Here, The positive value of net filtration depicts that the net filtration will take place.

also,

At venous end

Net filtration pressure =  ΔP₂ - Δπ = 24 - 25 = -1 mm Hg

Here, The negative value of net filtration depicts that the net absorption will take place.

Hence,

The correct answer is Net Filtration and Net Absorption

no , per capita income is not a true measure of the development because: -it only tells us about average income not how income is distributed among the people.it only give us an idea of the economic aspect.it is only at the qualitative basis.moreover, income is not only the way of development other factors are also as much as important as income.
