Steps of excretory system can be classified into formation of urine in kidneys which again include three processes viz. ultrafiltration, reabsorption and renal secretion. Then it is followed by flowing of urine from kidney to urinary bladder via ureters. From urinary bladder during micturition the urine is expelled out through urethra.

What process that breaks down complex molecules of food into smaller particles is called what?
PROCESS: DIGESTIONFunctions of the digestive systemThe digestive system prepares nutrients for utilization by body cells through six activities, or functions.IngestionThe first activity of the digestive system is to take in food through the mouth. This process, called ingestion, has to take place before anything else can happen.Mechanical digestionThe large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.Chemical digestionThe complex molecules of carbohydrates, proteins, and fats are transformed by chemical digestion into smaller molecules that can be absorbed and utilized by the cells. Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules. Digestive enzymes speed up the hydrolysis process, which is otherwise very slow.MovementsAfter ingestion and mastication, the food particles move from the mouth into the pharynx, then into the esophagus. This movement is deglutition, or swallowing. Mixing movements occur in the stomach as a result of smooth muscle contraction. These repetitive contractions usually occur in small segments of the GI tract and mix the food particles with enzymes and other fluids. The movements that propel the food particles through the GI tract are called peristalsis. These are rhythmic waves of contractions that move the food particles through the various regions in which mechanical and chemical digestion takes place.AbsorptionThe simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.EliminationThe food molecules that cannot be digested or absorbed need to be eliminated from the body. The removal of indigestible wastes through the anus, in the form of feces, is defecation or elimination.
Does scientist recognize six kingdoms of organisms?
No, scientists do not recognize six kingdoms of organisms anymore. The current classification system known as the three-domain system divides all living organisms into three domains: Bacteria, Archaea, and Eukarya. These domains are further subdivided into various kingdoms, such as Animalia, Plantae, Fungi, and Protista.
