What removes liquid and solid wastes from the body?
The anus removes all the waste from the body that couldn't be digested. This can be shown during excretion.
The excretory system removes liquid and solid wastes from the body.
The most important organs of the excretory system are the kidneys (for removal of liquid wastes) and the large intestine (for solid wastes).
The urinary system
The major organs for removing liquid waste are the kidneys, which filter the blood.
After filtration, wastes such as urea, salts, and excess water pass into the collecting ducts.
The urine passes to the ureter and the urinary bladder, which leaves the body through the urethra.
The digestive system
After the stomach and small intestines have removed the nutrients from food, the material that could not be digested passes into the large intestine.
Bacteria in the large intestine further break down this material,
The large intestine removes solid waste and some water in the form of feces, which pass out of the body in a process called defecation.
