​Body systems work together for…Regulation of Internal Environment (Homeostasis)

​

​

• Circulatory - regulates body temperature (e.g., an increase in body temperature causes blood vessels near the skin surface to dilate and release heat)

• Endocrine - regulates concentration of sugar in the blood (e.g., a high concentration of sugar in the blood triggers release of the hormone insulin which causes cells to take in sugar)

• Excretory - regulates level of water in the blood (e.g., a low level of water in the blood triggers retention of water by the kidneys)

• Integumentary - regulates body temperature (e.g., an increase in body temperature causes the skin to make and release sweat to cool the body)

• Nervous - regulates body responses (e.g., processes internal and external stimuli and sends signals throughout the body to coordinate and execute both the voluntary and involuntary processes that maintain homeostasis)

• Respiratory - regulates level of carbon dioxide in the blood (e.g., a high concentration of carbon dioxide triggers faster breathing)

Open Ended

IN YOUR OWN WORDS, describe how one of your body systems helps maintain homeostasis/ regulates your internal environment.

​Body systems work together for…Nutrient Absorption

​

​

• Circulatory - transports nutrients and oxygen to body cells, which enables cells to generate ATP via cellular respiration and transports cellular waste (carbon dioxide) away from cells

• Digestive - breaks down food ingested into smaller particles so it can be absorbed and used by cells

• Endocrine - controls the rate at which body cells utilize nutrients for energy through hormones (e.g., insulin, glucagon)

• Excretory - eliminates waste

• Muscular - moves food through the digestive tract

• Nervous - controls eating and drinking behavior and the muscles used for eating and elimination of wastes

• Respiratory - exchanges oxygen and carbon dioxide with the external environment

• Skeletal - stores mineral reserves

IN YOUR OWN WORDS, describe how your body systems work together to make sure that your cells get the nutrients that they need.

​Body systems work together for… Defense Against Injury or Illness

​

​

• Circulatory - transports white blood cells to fight infection

• Integumentary - acts as a barrier to prevent pathogens from entering the body

• Immune/Lymphatic - fights disease and infection

• Nervous - stimulates defense mechanisms against infection, like increasing body temperature (e.g., fever)

• Skeletal - produces white blood cells
