The digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After food is chewed and swallowed, it goes down the esophagus and enters the stomach, where it is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesn't need or can't digest is turned into waste and is eliminated from the body. 

Urinary System 

The urinary system eliminates waste from the body, in the form of urine. The kidneys remove waste from the blood. The waste combines with water to form urine. From the kidneys, urine travels down two thin tubes called ureters to the bladder. When the bladder is full, urine is discharged through the urethra.

The digestive system and Excretory System are the different mechanisms of the body, equipped with tissues and organs to carry out different functions.

What are the similarities in the excretory and digestive systems?

The digestive system is involved in the breakdown of complex food substances into small pieces, which can be absorbed and digested by the human body.

The excretory system is involved in the elimination of toxic and harmful substances from the body through a series of reactions.

The systems of the human body work similarly as the digestive system discards the undigestable and unhealthy food substances, which are then further eliminated by the excretory system running parallel.

Thus, the systems of the human body function collectively for the metabolism of food products.
