Components: skeletal muscle
Functions: movement, stabilize body, generate heat
Components/Functions of Nervous System
Components: brain, spinal cord, nerves, special sense organs (eyes and inner ear structures)

Liver, gall bladder, pancreas (secrete substances into the tract)
Functions: collectively break down food, absorb nutrients, eliminate wastes
Components/Functions of Urinary system
Components: kidneys, ureters, urinary bladder, urethra
Functions: produces/eliminates urine, eliminates wastes, regulates production of red blood cells
Components/Functions of Reproductive system
Components: gonads (testes, ovaries) and sex associated organs (fallopian tubes, uterus, vagina, mammary glands / epididymis, ductus deferens, seminal vesicles, prostate, and penis
Functions: produces/stores gametes (sperm/oocytes), produces hormones
Components/Functions of Endocrine system
Components: hormone producing glands/cells
Functions: produce hormones to regulate body activity, respond to changes in body’s internal/external environments
