The respiratory system play an important role in the the transport of oxygen and carbon dioxide in and out of the body thus maintaining the homeostasis of oxygen carbon dioxide ratio in our body which is very very important in maintaining the normal body physiology.
On the other hand the excretory system maintaintain homeostasis by interaction with respiratory system.Excretory system helps in the removal of waste material such as urea,ammonia and uric acid from our body through urine.The accumulation of waste products can hamper the normal body physiology.Thus excretory system also helps in maintaining the homeostasis of our body.
