Integumentary system
protects against environmental hazards; helps control body temperature
Skeletal system
Provides support; protects tissue; stores minerals; forms blood
Muscular system
Allows for locomotion; provides support; produces heat
Nervous system
Directs immediate response to stimuli, usually by coordinating the activities of other organ systems
Endocrine system
Directs long-term changes in activities of other organ systems
Cardiovascular system
Transports cells and dissolved materials, including nutrients, wastes, and gases
Lymphatic system
Defends against infection and disease; returns tissue fluid to the bloodstream
Respiratory system
Delivers air to sites where gas exchange can occur between the air and circulating blood
Digestive system
Processes food and absorbs nutrients
Urinary system
Eliminates excess water, salts, and waste products
Reproductive system
Produces sex cells and hormones
