2.69 urtinary system

1. In the urinary system we have: 
• two kidneys- a left one and a right one, each with its own blood supply, carrying out the process of excretion, filtration, and osmoregulation. From each kidney there is a tube that leads to the bladder, which is called a ureter. 
• ureter-carries urine from the kidney to the bladder. 
• Bladder- the urine is conducted to the outside of the body to be excreted down a structure called the urethra, which either travels down through the vagina or the penis.
