Functions

The excretory system is in charge of getting rid of waste in your body. Your kidneys, bladder, and urethra are important organs in regulating and removing extra liquid. These organs work with the circulatory system.

Major Organs

Kidneys - First, blood carries nutrients and water to your kidneys. Next your kidneys act as a filter deciding what nutrients your body needs and what it doesn’t need. The nutrients and extra water your body doesn’t need are sent to your bladder.

Bladder -Your bladder acts as a storage tank for extra water and nutrients. Then, you remove the extra water and nutrients when you pee.

Interactions with Other Systems

Ever wonder how your circulatory system gets rid of things it doesn't use? Let's find out! The circulatory system works very closely with the excretory system to excrete unused nutrients and waste products of chemical reactions in your body. The blood filters through the kidneys. The 'clean' blood goes back into your body, and the waste removed is removed from your body in the form of urine.
