Section 2

Question Answer
Integumentary systemprotects against environmental hazards, regulates body temperature and provides sensory info.
Skeletal systemprovides support and protection for tissues, stores calcium and other minerals, and forms blood cells.
Muscular systemin charge of movement, protecting and supporting tissues, and is main source of heat generation.
Nervous systemcoordinates activities of organ systems, and provides and interprets sensory information about external conditions.
Endocrine systemadjusts metabolic activity and energy use, and controls changes during development.
Cardiovascular systemdistributes blood cells, water, nutrients, waste, and gases. Also distributes heat and assists in controlling body temp.
Lymphatic systemdefends against infection and disease.
Respiratory systemdelivers air to alveoli, provides oxygen to bloodstream, and removes carbon dioxide from blood stream. Also has role in producing sound.
Digestive systemdigests food, absorbs nutrients and conserves water.
Urinary systemexcretes waste products from blood, controls water balance, and regulates blood ion concentration and pH
Reproductive systemproduction of sex cells and hormones, and development of embryo.
