• maintaining boundaries

• movement

• digestion

• metabolism

• excretion

• reproduction

• growth/development

integumentary

maintaining boundaries

• creates a boundary on the outside of the body to keep bad things out of the body, and separates the internal environment of the body from the outside

• prevents vital fluids from evaporating and leading to dehydration

muscular system

movement

• muscles can contract (get shorter and pull on the bones) which produces movement

nervous system

responsiveness/excitability

• if outside temp changes, nervous system detects it through outside stimulus and causes you to sweat

• body communicates through electrical impulses and hormones

• receptors detect change, control center dictates necessity of regulation, effector carries out the response

digestive system

digestion

• breaks down foods we digest so the body can use the energy and it can be absorbed by bloodstream

endocrine system

metabolism

• through thyroid hormone

  • thyroid hormones control basal metabolic rate - how fast your body burns energy at rest

respiratory system

excretion

• we breath in oxygen and excrete carbon dioxide since we do not need that gas

reproductive system

reproduction

• male produces sperm, female produces egg which is fertilized to create a baby

endocrine system (2)

growth development

• produces the growth hormone from the pituitary gland to aid the elongation of bones, growth of muscles, and increase of organ size
