The large intestine.
The kidneys belong to the urinary system. They are vital organs responsible for filtering waste products from the blood to form urine, regulating blood pressure, and maintaining electrolyte balance in the body.

Ammonia is the waste product in the body that contains one part nitrogen and three parts hydrogen.
The skin excretes waste by persperation or sweeting and letting the salts out by opening the pores.
The kidney filters the blood, removing excess potassium and urea and expelling it out through the ureters and finally the urethra. The kidney's other main function is reabsorb water, glucose, amino acids, and salt. It regulates all those levels in the body.

The circulatory system does all this but the blood and plasma are the "part" that you are talking about. The hemoglobin carries the oxygen and some of the waste gas called carbon dioxide but the plasma carries the rest. The plasma is the liquid part of the blood.
If you mean what body system it's a part of the Digestive System
The circulatory system is the system in the body that is responsible for the transportation of materials throughout the body. Red blood cells move through the circulatory system deliver oxygen and water to the cells in the body and takes away waste products.
The urinary system removes waste products, excess ions, and water from the body by filtering the blood in the kidneys to produce urine. Urine travels from the kidneys to the bladder through the ureters and is then expelled from the body through the urethra during urination.
The Pores
It could be seen that way as they are part of "shipping and receiving". The vacuoles are the trash bins. The colon removes water but also dumps waste that the body can't use. So both could be true.
The kidneys are responsible for removing waste products, including urea, from the blood and creating urine. Urea is a byproduct of protein metabolism and is filtered by the kidneys to be excreted from the body.

the kidney, which is part of the excretory system.
Humans have nine major organ systems. The Excretory System removes waste materials from the body. The Endocrine System secrete hormones.
The kidneys filter nitrogenous waste products from the blood and excrete them in the form of urine. This process helps maintain the body's balance of water, salts, and other substances.
