Explain the major organs and functions of the integumentary system?
Major organs: Skin, Hair, Sweat glands, and Nails
Functions: Protects against environmental hazards, Helps regulate body temperature, Provides sensory information
Explain the major organs and functions of the skeleton system?
Major Organs: Bones, Cartilages, Associated ligaments, Bone marrow
Functions: Provides support and protection for other tissues, stores calcium and other minerals, Forms blood cells
Explain the major organs and functions of the muscular system?
Major Organs: Skeletal muscles and associated tendons
Functions: provides movement, Provides protection and support for other tissues, Generates heat that maintains body temperature
Explain the major organs and functions of the nervous system?
Major Organs: Brain, Spinal cord, Peripheral nerves, Sense organs
Functions: Directs immediate responses to stimuli, Coordinates or moderates activities of other organ systems, Provides and interprets sensory information about external conditions
Explain the major organs and functions of the cardiovascular system?
Major Organs: Heart, Blood, Blood vessels
Functions: Distribute bloods cells, water and dissolved materials, including nutrients, waste products, oxygen, and carbon dioxide and distributes heat and assists in control of body temperature
Explain the major organs and functions of the endocrine system?
Major Organs: Pituitary gland, Thyroid gland, Pancreas, Suprarental glands, Gonads (testes and ovaries), and endocrine tissues in other systems
Functions: 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
Explain the major organs and functions of the lymphatic system?
Major Organs: Spleen, Thymus, Lymphatic vessels, Lymph nodes, Tonsils
Functions: Defends against infection and disease, Returns tissue fluids to the bloodstream
Explain the major organs and functions of the respiratory system?
Major Organs: Nasal cavities, Sinuses, Larynx, Trachea, Bronchi, Lungs, Alveoli
Functions: Delivers air to alveoli (sites in lungs where gas exchange occurs), Provides carbon dioxide from bloodstream, Produces sounds for communication

Major Organs: Teeth, Tongue, Pharynx, Esophagus, Stomach, Small intestine, Large intestine, Liver, Gallbladder, Pancreas
Functions: Processes and digests food, absorbs and conserves water, absorbs nutrients, stores energy reserves
Explain the major organs and functions of the urinary system?
Major Organs: Kidneys, Ureters, Urinary bladder, Urethra
Functions: Excretes waste products from the blood, Controls water balance by regulating volume of urine produced, stores urine prior to voluntary elimination, regulates blood ion concentrations and pH
