If you are on A+ it is the Excretory System. Well, actually it's the Excretory System where-ever you go.
Blood delivers oxygen and nutrients to the body cells, and it removes waste and takes it to the kidneys where it is filtered from the blood and passed to the bladder. From there, it is passed out of the body through urinating.
The excretory system eliminates liquid waste from the body. This system includes the kidneys, which filter waste from the blood to produce urine, and the bladder, which stores the urine until it is expelled from the body through the urethra.
The digestive system is responsible for processing food and extracting nutrients from it, while the excretory system is responsible for removing undigested food and liquid waste from the body through the process of defecation.

Blood delivers oxygen and nutrients to the body cells, and it removes waste and takes it to the kidneys where it is filtered from the blood and passed to the bladder. From there, it is passed out of the body through urinating.
The filtrate is the liquid that passes through the filter paper and contains the substances that have been filtered. The residue is the solid material that remains on the filter paper after the liquid has passed through.
Urine contains waste products and excess substances that the body needs to eliminate, such as water, salts, and urea. These components are filtered from the blood by the kidneys and passed out of the body through the urinary system as urine.
Waste products like urea, creatinine, and excess ions are filtered out of the blood by the kidneys and passed on to the bladder as urine to be excreted from the body.
