Why do capillaries need to be thin walled?

Answer

To allow effective diffusion of nutrients and oxygen to the cells and also diffusion of waste and carbon dioxide from the cells

Explanation.

-Capillaries are small vessels that are only one cell thick; which is an adaptation that allows them to undertake their function effectively.

-The function of capillaries is to allow food and oxygen to diffuse to cells while waste is diffused from cells.

-Therefore; they need to be thin walled for these functions.

-If the capillaries did not have thin walls, the gases could not diffuse through, which would be difficult to carry out their functions.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
