The proximal end of a nephron is closed.What is this modification

Answer 1

The proximal end of a nephron is closed. What is this modification? The proximal part of a neuron is closed and form Malpighian body to filter the blood collected from the blood vessels. Hence it is a structural adaptation of neuron for the formation of primary urine.

Answer 2

The modification which results in enclosure of the proximal part of the nephron is called the Malpighian body or the Malpighian corpuscle.

It consists of a cup-shaped end along with a glomerulus that encloses. The Malpighian body filters the collected blood and forms the primary urine.

The renal tubule and the renal corpuscle are the two pars of a nephron. Resorption, filtration and excretion are the main duties of the nephron.
