EXCRETORY SYSTEM
A passive biological system that removes excess, unnecessary materials from an organism, so as to help maintain homeostasis within the organism and prevent damage to the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and gaseous wastes, as urine and as a component of sweat and exhalation.  Removes metabolic and liquid toxic wastes as well as excess water from the organism, in the form of urine.

Component Organs
LUNGS
One of the main functions of this is to diffuse gaseous wastes, such as carbon dioxide, from the bloodstream as a normal part of respiration. Kidneys
Its primary function is to eliminate the waste from the bloodstream by prod Ureter
This is the muscular ducts that propel urine from the kidneys to the urinary bladder. In the human adult, the ureters are usually 25-30 cm (10-12 in) long. Urinary bladder
It is the organ that collects urine excreted by the kidneys prior to disposal by urination. It is a hollow muscular and distensible (or elastic) organ, and sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. Urethra

It’s a tube which connects the urinary bladder to the outside of the body. In humans, the urethra has an excretory function in both genders to pass.

Urine formation
Within the kidney, blood first passes through the afferent artery to the capillary formation called a glomerulus and is collected in the Bowman’s capsule, which filters the blood from its contents—primarily food and wastes. After the filtration process, the blood then returns to collect the food nutrients it needs, while the wastes pass into the collecting duct, to the renal pelvis, and to the ureter, and are then secreted out of the body via the urinary bladder.

Excretion and Body Waste Products
Just as your living body cells need oxygen to burn food for fuel or energy, they must also give off waste products. The blood that brings food and...
