Interactions Between Systems

Nervous

(controls all other systems) Hypothalamus - maintains homeostasis by working with all systems

Digestive

1) w/ circulatory - absorbs deliver the digested nutrients to the cell 2) w/ muscular - control the contractions of many of the digestive organs to pass food along 3) w/ nervous - hypothalamus maintains homeostasis by triggering appetite (stomach growling), digest.

Excretory

1) w/ circulatory - filters waste out of blood 2) w/ lungs - removes excretory waste 3) w/ integumentary - removes excretory waste

Immune

1) w/ circulatory - transports WBC's to fight invaders 2) w/ lymphatic - has lots of WBC's to fight invaders, spleen filters bacteria/ viruses out of blood 3) w/ skeletal - WBCs made in bone marrow 4) w/ integumentary - prevents invaders from getting in

Endocrine

1) w/ circulatory - transports hormones to target organs 2) w/ nervous - maintain homeostasis, hormone release 3) w/ reproductive - controlled by hormones 4) w/ skeletal - controls growth of bones

Skeletal

1) w/ muscular - allows movement 2) w/ circulatory - produce blood cells 3) w/ immune - produce white blood cells 4) w/ circulatory & respiratory - protects its organs

Circulatory

1) w/ respiratory - delivers O2 from lungs to cells and drop off Co2 from cells to lungs 2) w/ digestive - absorb and deliver digested nutrients to the cells 3) w/ excretory - kidneys filter cellular waste out of blood for removal 4) w/ lymphatic - both transport things to and from cells 5) w/ immune- transport WBCs throughout body to fight disease 6) w/ nervous - brain controls heart beat 7) w/ endocrine - transports hormones

Muscular

1) w/ skeletal - allow movement 2) w/ digestive - allow organs to push food through 3) w/ respiratory - diaphragm controls breathing 4) w/ circulatory - controls pumping of blood (heart) 5) w/ nervous - controls all muscle contractions
