About 150 l of plasma filters into the renal tubules each day, but only 1-2 l of urine is formed. what happens to the rest of the plasma fluid?

The rest of the plasma fluid is reabsorbed into the blood stream. This comprises of the nutrients and water. The unwanted materials i.e. solutes, water etc do concentrate to form the urine and the other filtrated products are therefore reabsorbed.

explanation:

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
