As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). If the blood speed in

Semenov [28]

Answer:

$A_2 = 2.5\ cm^2$

Explanation:

given,

velocity factor = 4

Cross-sectional area of venules(A₁) = 10 cm²

cross sectional area of capillaries(A_2) = ?

continuity equation = Q = AV

now,

$\dfrac{A_1}{A_2} = \dfrac{V_2}{V_1}$

$\dfrac{10}{A_2} =4$

$\dfrac{10}{4} =A_2$

$A_2 = 2.5\ cm^2$

hence, the area of capillaries is equal to 2.5 cm₂

I believe the answer to your question is “Lithosphere plate boundaries”

The planet Earth is covered by a layer formed by land and rocks called the earth's crust or lithosphere. This crust is not smooth and uniform, but rather irregular and composed of tectonic plates, also called lithosphere plates. These plates are not fixed as they are under the magma (high temperature molten rock).

Hope this helps!:)
