integumentary function

protect against environmental hazards

skeletal function

• provide support

• protect tissues

• store minerals

• form blood cells

muscular function

• produce movement

• provide support

• generate heat

nervous function

• respond to stimuli

• coordinate the activities of other organ systems

endocrine function

direct long term changes in other organ systems with hormones

cardiovascular function

transport nutrients, hormones, wastes, gasses, and more

• supply oxygen and nutrients to the whole body

lymphatic function

• defend against infection and disease

• return fluid to the bloodstream

respiratory function

• delivers air to sites where gas exchange occurs between the air and circulating blood

• produces sound

digestive function

• processes food and absorbs nutrients (carbs, fats, proteins, minerals, and water)

urinary function

• eliminates excess water, salts, and wastes

• controls pH

reproductive function

• produces sex cells and hormones

• supports encryption development from fertilization to birth (F)
