Organ Systems Flashcards
Skeletal system
Bones, cartilage, associated ligaments, bone marrow
Provides support and protection for other tissues, stores calcium and other minerals, forms blood cells
Muscular system
Skeletal muscles and associated tendons
Provides movement, provides protection and support for other tissues, generates heat that maintains body temperature
Nervous system
Brain, spinal cord, peripheral nerves, sense organs
Directs immediate responses to stimuli, coordinates or moderates activities of other organ systems, provides and interprets sensory information about external conditions
Endocrine system
Pituitary gland, thyroid gland, pancreas, suprarenal glands, gonads, endocrine tissues in other systems
Directs long-term changes in the activities of other organ systems, adjusts metabolic activity and energy use by the body, controls many structural and functional changes during development
Cardiovascular system
Heart, blood, blood vessels
Distributes blood cells, water, and dissolved materials, including waste products, oxygen, and carbon dioxide; distributes heat and assists in control of body temperature
Lymphoid system
Spleen, thymus, lymphatic vessels, lymph nodes, tonsils
Defend against infection and disease, return tissue fluids to the bloodstream
Respiratory system
Nasal cavities, sinuses, larynx, trachea, bronchi, lungs, alveoli
Delivers air to alveoli, provides oxygen to blood stream, removes carbon dioxide from bloodstream, produces sounds for communication
Digestive system
Teeth, tongue, pharynx, esophagus, stomach, small intestine, large intestine, liver, gallbladder, pancreas
Process and digest food, absorb and conserve water, absorb nutrients, stores energy reserves
Urinary system
Kidneys, ureters, urinary bladder, urethra
Excretes waste products from the blood, controls water balance by regulating volume of urine produced, stores urine prior to voluntary elimination, regulates blood ion concentration and pH
Reproductive system (male)
Testes, epididymides, ductus deferens, seminal vesicles, prostate gland, penis, scrotum
Produces male sex cells, suspending fluids, and hormones; sexual intercourse
Reproductive system (female)
Ovaries, uterine tubes, uterus, vagina, labia, clitoris, mammary glands
Produces female sex cells and hormones, supports developing embryo from conception to delivery, provides milk to nourish newborn infant, sexual intercourse
Integumentary system
Skin, hair, sweat glands, nails
Protects against environmental hazards, helps regulate body temperature, provides sensory info
