func skeletal
to provide structure and support movement + protection
nervous func
to coordinate + control body functions through electrical signals. Receive coordinate and respond to stimulus
muscular func
to support movement and transport
urinary func
to maintain fluid balance within the body and excrete wastes out of the body
endocrine func
to coordinate body function through synthesis and secretion of regulatory molecules (hormones)
Digestive function
To ingest and process foodstuffs for distribution and use by cells, elimination of waste (defection-absorption of nutrients)
Immune system function
To defend against foreign invaders e.g pathogens
Function of integumentary system
To protect from external environment
Cardiovascular system function
To transport materials between cells
(Nutrients & wastes)
Reproductive system function
To perpetuate species
Lymphatic system
To collect excess fluid from cells & return to the bloodstream immune function
Respiratory system function
To take in oxygen and provide a site for gaseous exchange of oxygen in which carbon dioxide is produced between internal and external environments
