Digestive &Circulatory
blood carries digested nutrients from food to the body
nervous &circulatory
brain stem controls heart rate
Excretory& Circulation
The kidneys clean the blood and control the amount of salt, water, and other substances in the blood
musculoskeletal & circulatory
Oxygen-rich blood is delivered to muscles during exercise
circulatory and respiratory
Oxygen is delivered to the cells in the body
SQ

weathering
digestive & respiratory
oxygen is inhaled and helps provide energy to the stomach muscles for digestion
nervous & respiratory
brain monitors respiratory volume and gas levels
excretory & respiratory
Carbon dioxide is released from the body
Muscoskeletal & respiratory
The diaphragm is a muscle that allows involuntary breathing to occur
Chemical signals are carried through the body in the bloodstream to help the speed of digestion
respiratory& digestive
oxygen is delivered to stomach muscles to aid in digestion
SQ
