The function of the excretory system is

• the elimination of carbon dioxide from the blood

• the elimination of waste produced by the chemical processes in our body

• the production of urine

• the absorbtion of urine into blood

The kidneys

• filter blood and produce urine

• produce ammonia from amino acids and release it into blood

• absorb water from the cells

• store urine

The ureter

• transports urine from the kidneys to the bladder

• transports urine from the bladder to the kidneys

• transports urine out of the body

• transports blood to the kidneys

The urinary bladder

• produces urine

• temporarily stores blood before filtration

• stores urine before micturition

• filters urine

The urethra

• transports "clean" blood to the circulatory system

• transports urine out of the body

• transports "dirty" blood to the kidneys

• transports urine out of the kidneys

The excretory system helps balancing the levels of fluids and salts in blood and body
