6At one end is a cup-like structure called the Bowman's capsule At one end is a cup-like structure called the Bowman's capsule. It encloses a knot of capillaries called the glomerulus. These capillaries are leaky and small molecules get filtered out and end up inside the Bowman's capsule. This process is called ultrafiltration.If nothing else happens then the materials, such as water and urea, will end up going all the way through the nephron, down the ureter, through the bladder and out of the body.However, sometimes the body needs to grab back chemicals such as water and glucose which are still useful. This happens when they move out of the fluid in the nephron back into the capillary network that twists around the nephron.This process is called reabsorption. Reabsorption means that the useful chemicals are taken back into the blood out of the nephron. They do not end up in the urine and are not lost by the body.
