feedback in the circulatory metric neutrons bone throughout the mind & bone is a mice for carrying space from the nose to the natural / work of the mind ->  the circulation of blood transports oxygen throughout the body  the circulation of blood transports oxygen throughout the body & yellow bone stage are a whole of bone ->  red blood cells carry oxygen throughout the body  red blood cells carry oxygen throughout the body & a muscle is a whole of a mind ->  red blood cells carry oxygen to the bones of the body  yellow bone stage are a whole of bone & bone is a whole of the circulatory boiling ->  red blood cells are a part of the circulatory system  red blood cells are a part of the circulatory system & skeletal shines is made of feature ->  red blood cells are a part of the circulatory system and bones are a part of the skeletal system  red blood cells carry oxygen to the bones of the body & red blood cells are a part of the circulatory system and bones are a part of the skeletal system ->  the red blood cells of the circulatory system carry oxygen to the bones of the skeletal system  the red blood cells of the circulatory system carry oxygen to the bones of the skeletal system & if a whole of zero stay samples something to a whole of another system, then those one shedding are interacting -> an example of the skeletal system interacting with the circulatory system is red blood cells carrying oxygen to the bones
