What is the force that causes filtration of the blood by capillaries in the kidneys to occur?

Renal ultrafiltration is the known force to cause blood by capillaries in the kidneys to occur.

it would lead to upper respiratory infections and pneumonia.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
