- Excretory sytem does the removal of waste products and this system must function properly in order to maintain homeostasis.
- Digestive system helps maintain its homeostasis by changing the PH from the saliva.This makes an acidic environment that helps break down food really fast and protects your body from bacteria.
- The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells.
Just so you know, The release of hormones into the blood is controlled by a stimulus.
