Excretory system

Components of the excretory system

• Kidneys,
• ureter (ureter),
• bladder (vesica urinaria),
• urethra (urethra).

Kidneys

The kidney is a paired organ whose function is the formation of primary urine and subsequent adjustment into definitive urine. By eliminating waste substances and metabolites, it serves to maintain Homeostasis and Acid-base balance. The endocrine function of the kidneys ensures the maintenance of water in the body and the regulation of blood pressure.

Ureter

paired tubular organ, urinary transport through the ureter is not a passive process - it is ensured by contractions of the muscular layer of the ureter
