Mae'r modelau system wrinol 3d yn system o organau sy'n ffurfio, cronni ac ysgarthu wrin mewn pobl. Mae'n cynnwys pâr o arennau, dau wreter, bledren ac wrethra. Nebridium yw analog infertebratau.

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).

Mewn bodau dynol, mae'r bledren yn organ cyhyrog gwag wedi'i leoli'n retroffitol yn y pelfis. Mae'r bledren yn gwasanaethu cronni wrin. Mae gallu'r bledren ar gyfartaledd yn 500-700 ml ac mae'n agored i amrywiadau unigol mawr. Mae maint y bledren yn amrywio yn ôl ei gynnwys ymestynnol. Yn absenoldeb clefyd, gall y bledren ddal 300 ml o wrin yn ddiogel ar gyfer oriau 2-5.

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.
