Question

Ultrafiltering units of kidney are known as

• A. Vena Cava
• B. Glomerulus
• C. Nephron
• D. Tubule

Answer 1

The correct option is B Glomerulus

The first step in making urine is to separate the liquid part of your blood (plasma), which contains all the dissolved solutes, from your blood cells. Each nephron in the kidneys has a microscopic filter, called a glomerulus that is constantly filtering the blood. Blood that is about to be filtered enters a glomerulus, which is a tuft of blood capillaries (the smallest of blood vessels). The glomerulus is nestled inside a cup-like sac located at the end of each nephron, called a glomerular capsule. Glomerular capillaries have small pores in their walls, just like a very fine mesh sieve. The physical characteristics of the glomerular capillary wall determine what is filtered and how much is filtered into the glomerular capsule.

So the correct option is 'glomerulus'.
