Sistem urin model 3d adalah sistem organ yang membentuk, menumpuk, dan mengeluarkan urin pada manusia. Terdiri dari sepasang ginjal, dua ureter, kandung kemih dan uretra. Analog invertebrata adalah Nefridium.

The kidneys are the organs of a bean-shaped form, measuring 10–12 cm in length, 5–6 cm in width, and 3–4 cm in thickness, located in the retroperitoneal space, near the lumbar spine. The kidneys are surrounded by perinephral fat; up and several anterior to the kidneys are the adrenal glands. The kidney performs many functions – the concentration of urine, the maintenance of electrolyte and acid-base homeostasis. The kidney secretes and reabsorbs (reabsorbs) electrolytes (sodium, potassium, calcium, etc.) under the control of local and systemic hormones (renin-angiotensin system).

Pada manusia, kandung kemih adalah organ berotot berongga yang terletak retroperitoneal di panggul. Kandung kemih berfungsi untuk menumpuk urin. Kapasitas kandung kemih rata-rata 500-700 ml dan tunduk pada fluktuasi individu yang besar. Ukuran kandung kemih bervariasi tergantung pada isi peregangannya. Jika tidak ada penyakit, kandung kemih dapat dengan aman menahan 300 ml urin selama 2-5 jam.

The final part of the excretory system is the urethra (urethra). The urethra differs in men and women – in men it is long and narrow (22-24 cm long, up to 8 mm wide), and in women – short and wide. In the male body, ducts that carry sperm also open into the urethra.
