Central cavity. Urine formed after blood purification is deposited here. This cavity is connected to the ureter, so urine flows directly into the bladder.

The nephron is the functional unit found within the kidneys. Each kidney consists of millions of microscopic nephrons, each with a rich blood supply.

The nephron is the functional unit located outside the kidneys. Each kidney consists of 100 microscopic nephrons, each with a rich blood supply.

Each nephron contains the following structures:

A mass of capillaries surrounded by Bowman's capsule.

It takes blood away from the glomerulus.

The structure consisting of Bowman's capsule and glomerulus

• There are three basic kidney processes:

Urine formation: • Filtration of plasma from the glomerular capillaries into Bowman's space.

Urine formation: • Filtration of plasma from the efferent arteriole capillaries into Bowman's space.

The process that moves from the tubular lumen to the capillaries surrounding the tubules is called ____)

The process by which blood moves from the capillaries surrounding the tubules to the tubular lumen is known as ____)

Less than 1% of albumin molecules leak from Bowman's capsule. Those that do leak are removed by exocytosis in the proximal tubule.

Less than 2% of albumin molecules leak from Bowman's capsule. Those that do leak are removed by exocytosis in the proximal tubule.
