The respiratory and circulatory systems work together to maintain homeostasis
The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues
The digestive system and the respiratory system share common anatomical structures.
The respiratory and circulatory systems must work together to produce energy in the form ATP needed for the cell to function.
Circulatory System
Pumps blood through Respitory system
The circulatory system also carries chemical signals from your endocrine system that control the speed of digestion.
The excretory system is a close partner with both the circulatory,blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system.
Carbon Dioxide
the air we breathe out has more carbon dioxide
Oxygen
The respiratory system works directly with the circulatory system to provide oxygen to the body
Digestive System
Digestive System works very closely with the circulatory system to get the absorbed nutrients distributed through your body.
The digestive system breaks food down into nutrients such as glucose.
