4. Integumentary system: skin, hair and nails
5. Immune system: the system that fights off disease; composed of leukocytes, tonsils, adenoids, thymus, and spleen.
6. Lymphatic system: structures involved in the transfer of lymph between tissues and the blood stream, the lymph and the nodes and vessels that transport it.
7. Musculoskeletal system: movement with muscles and human skeleton (structural support and protection with bones, cartilage, ligaments, and tendons).
8. Muscular system: the system that moves the body with muscles, ligaments, and tendons.
9. Nervous system: collecting, transferring and processing information with brain, spinal cord, peripheral nerves, and nerves
10. Reproductive system: the sex organs; in the female; ovaries, fallopian tubes, uterus, vagina, mammary glands, and in the male; testes, vas deferens, seminal vesicles, prostate, and penis.
11. Respiratory system: the organs used for breathing, the pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
12. Skeletal system:the system that holds the body together and gives it shape; composed of bones, cartilage, and tendons.
13. Urinary system: kidneys, ureters, bladder and urethra involved in fluid balance, electrolyte balance and excretion of urine.
14. Vestibular system : contributes to our balance and our sense of spatial orientation.
