The human excretory system helps remove waste from the body. Important parts and their functions are:
1. Kidneys: Filter waste and excess water from the blood to make urine, and help regulate fluid balance and blood pressure.
2. Ureters: Tubes that carry urine from the kidneys to the bladder.
3. Urinary bladder: Stores urine until it's ready for release.
4. Urethra: Tube that carries urine from the bladder out of the body.
5. Renal artery and renal vein: Artery brings blood to the kidneys for filtration, vein carries filtered blood away.
6. Cortex and medulla: Parts of the kidney that contain nephrons to filter blood and produce urine.
7. Pelvis: Funnel-shaped area in the kidney that collects urine before it goes to the bladder.
In conclusion,the excretory system helps maintain balance in our bodies by removing waste and regulating water and electrolyte levels.
