Urea
digestive system
An annelid excretes solid waste through its anus. However, metabolic wastes are excreted by its nephridia, a pair of organs.
The Urinary System is the answer.
The urinary system primarily excretes waste products such as urea, creatinine, and uric acid. These waste products are formed from the breakdown of proteins and nucleic acids in the body. Additionally, the urinary system also eliminates excess water, electrolytes, and other metabolic waste products that are filtered from the blood by the kidneys.
There are several organs that are involved in the process of excretion; the pores of the skin that excrete oil and sweat, the lungs which excrete carbon dioxide, the rectum via the anal canal and anus that excretes feces, and the urinary tract which excretes urine via the urethra. Some anatomists consider the kidneys as the only excretory organ.
