What function does the Excretory system perform?

  1. Controls the steady circulation of blood through the body

  2. Breaks down foods into nutrients and wastes

  3. Purifies the body by eliminating waste matter

  4. Affects growth, development, and sexual functions

The correct answer is: Controls the steady circulation of blood through the body

While the excretory system plays a crucial role in eliminating waste matter from the body, its primary function is not purification. Rather, the excretory system is responsible for controlling the steady circulation of blood through the body by filtering out waste products and excess substances, such as water, electrolytes, and urea, from the blood to form urine. This process helps maintain the body's overall balance and functioning.
