Question

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 bodys breathing and heart rate d. the digestive system when food is broken down for nutrients

Explanation:

The nervous system, specifically the brain, plays a crucial - role in regulating the body's breathing rate and heart rate, which are key to maintaining homeostasis with the respiratory system. The excretory system deals with liquid waste and is not directly related to respiratory - homeostasis. The skeletal system is mainly for support and protection and not directly involved in this context. The digestive system is about breaking down food for nutrients and not directly related to respiratory - homeostasis.

Answer:

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