19. BODILY SYSTEM ROLES IN NUTRITION
1.Cardiovascular (heart, blood vessels,
blood)
Transport nutrients, gases, waste products;
regulates body temperature; involved with the
immune response
2. Digestive (mouth, esophagus, stomach,
intestines, liver, pancreas)
Digests and absorbs nutrients; eliminates
waste products
3. Endocrine (endocrine glands) Helps regulate metabolism, reproduction water
balance
4. Immune(wbc, lymph, spleen, thymus gland)Provides defense against foreign substances
5. Integumentary (skin, hairs, nails, sweat
glands)
Protects the body; regulates temperature, aids
in acid-base and water balance; production of
vitamin D

20. BODILY SYSTEM ROLES IN NUTRITION
6. Lymphatic (lymph vessels, nodes) Helps with fluid balance and fat absorption;
removes foreign substancs from the blood
7. Muscular (skeletal, cardiac and smooth
muscles)
Maintains posture; directs body movements;
produces body heat
8. Nervous (brain, spinal cord, nerves, sensory
organs, and receptors)
Controls intellectual function; detects
sensations and controls movements
9. Respiratory (lungs, and respiratory tract) Regulates gas exchanges and acid-based
balance
10. Reproductive Regulates sexual functions and reproduction

21. BODILY SYSTEM ROLES IN NUTRITION
11. Skeletal (bones, joints, cartilages) Main frame body support; aids with body
movements; stores minerals, produces blood
cells
12. Urinary (kidneys, urinary tract) Removes waste products; regulates fluid,
acid-based balance; aids with homeostasis
