With each heartbeat, blood flows through the kidneys. Each kidney contains up to a million filtering units called nephrons. Each nephron is made up of tiny capillary loops called a glomerulus. Millions of glomeruli (plural of glomerulus) filter urea, other waste and excess water from the blood.
The areas between the pyramids are called renal columns. The kidneys are regulatory organs which filter the blood to remove waste products, salts and water which are then secreted from the kidneys as urine. The main functional unit of the kidney is the nephron, and there are over a million nephrons in each kidney.he areas between the pyramids are called renal columns.
