The respiratory system supplies oxygen to the blood in the body, while removing carbon dioxide. which system directly interacts with the respiratory system to maintain homeostasis?
a
the excretory system when it sends out liquid waste as urea

b
the skeletal system when oxygen and glucose around the ribs are absorbed

c
the nervous system when the brain regulates the body's breathing and heart rate

d
the digestive system when food is broken down for nutrients

The correct answer is A the excretory system when it sends out liquid waste as urea

Explanation:

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.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
