How does the Excretory System Work?

The Excretory system works by transferring unwanted fluids outside of the body.

How does it work with other body systems?

The Excretory system works with both the circulatory and the endocrine systems. The interaction between the circulatory system and excretory system is the blood from the circulatory system flows to the kidneys urea, and uric acid are removed from most of the blood and the water is returned to the body. The endocrine system is a major controller of the excretory system. As levels of compounds and fluids are monitored, kidney function must be constantly altered to provide the best internal environment for your cells. `

Fun Facts:

Most humans pee 3,000 times per year with a regular lifestyle that doesn't require pushing fluids.

In the course of just 1 day, your blood will pass through your kidneys an average of 300 times.

Your skin will shed up to 40,000 skin cells every minute in order to replenish itself.

When you put all of the solid waste together, the average person uses toilet paper to clean up after 305 pounds of waste.

The average person breathes more than 6 million times over the course of their average life.

Diseases

Renal failure and sepsis are both diseases that happen in the excretory system.
