Organ Systems and Functions

integumentary system

skin and structures such as hair, nails, sweat and oil glands

integumentary system function

regulate body temperature, eliminate some wastes, detects sensations, protects

skeletal system

bones and joints of the body and their associated cartilages

skeletal system function

support and protect body, assist in movement, produces blood cells, stores mineral and lipids

muscular system

specifically skeletal muscle tissue

muscular system function

powers movements of the body, stabilizes body position, generates heat

cardiovascular/circulatory system

blood, heart, and blood vessels

cardiovascular/circulatory system function

pumped blood carries O2/nutrients to cells and CO2 away, regulates pH, helps defend against disease, mend damaged blood vessels

lymphatic/immune system

lymph, lymphatic vessels, and structures containing lymphatic tissue such as spleen, thymus, and tonsils

lymmphatic/immune system function

returns proteins and plasma to cardiovascular system, matures WBCs, produces antibodies, transports fats from GI to cardiovascular system

nervous system

brain, spinal cord, nerves, and sense organs

nervous system functions

regulate body activities in response to internal and external stimuli, interpret stimuli and respond thru muscular contractions or glandular secretions

endocrine system

hormone producing glands such as the pituitary, thyroid, and pancreas

endocrine system function

regulate body activities thru hormones (chemicals transported in blood to target cells)

respiratory system

lungs and the airways leading into and out of them

respiratory system function

transfer oxygen from inhaled air to blood and carbon dioxide from blood to exhaled air, helps regulate blood pH 

digestive system

organs of the GI tract (mouth, esophagus, stomach, intestines) and accessory organs (salivary glands, pancreas, liver gallbladder)

digestive system function

physical and chemical breakdown of foods, absorbs nutrients, eliminated solid wastes

urinary system

kidneys, ureter, urinary bladder, urethra

urinary system function

regulate volume and chemical composition of blood (fluid + electrolytes) eliminate metabolic wastes (nitrogen/urea), maintain pH and calcium balance in body, secrete hormones regulating RBC production

reproductive system

gonads (testes/ovaries), uterus, vagina, ductus deferens, epididymis, and penis

reproductive system function

produce games and release hormones that regulate reproduction, transport and store gametes
