Ok, how exactly does the kidney clean the blood and make urine?
The kidney contains many types of specialized cells. One functional unit of a kidney is called a nephron. Each kidney has around a million nephrons, and every nephron has 2 parts:
- Glomerulus (filter)
Step 1 The glomerulus receives circulated blood and acts as a filter. Water, electrolytes and urea pass through but large proteins such as albumin* are blocked.
Step 2 The tubule then reabsorbs the water and electrolytes your body needs.Excess material is eliminated and passes as urine. Healthy kidneys will adjust your elimination of water and electrolytes.
