Title: NERVOUS SYSTEM


1
NERVOUS SYSTEM
  • STRUCTURES
  • Brain
  • Spinal Cord
  • Nerves
  • FUNCTIONS
  • Receives/relays info about activities w/in the
    body
  • Monitors/responds to external/internal changes

2
SKELETAL SYSTEM
  • STRUCTURES
  • Bones
  • Cartilage
  • Bursa sacs
  • Ligaments
  • FUNCTIONS
  • Supports/shapes the body
  • Protects the internal organs
  • Acts w/ muscles to produce movement
  • Provides reserves of minerals
  • Is the site of blood-cell formation

3
MUSCULAR SYSTEM
  • STRUCTURES
  • Muscles (striated, smooth, cardiac)
  • Tendons
  • FUNCTIONS
  • Allows movement of the body and within the body
  • Maintenance of body posture
  • Production of heat

4
INTEGUMENTARY SYSTEM
  • STRUCTURES
  • Skin
  • Hair
  • Nails
  • Sweat Glands
  • Sensory Receptors
  • Sebaceous Glands
  • Membranes
  • FUNCTIONS
  • Protects the body by serving as a barrier against
    infection and injury
  • Regulates body temperature
  • Provides protection against UV radiation
  • Serves as a gateway for sensationnervous system

5
DIGESTIVE SYSTEM
  • FUNCTIONS
  • Mechanical and chemical breakdown of food
  • Absorption of nutrients
  • Elimination of undigested waste products
  • STRUCTURES
  • Mouth
  • Pharynx
  • Esophagus
  • Stomach
  • Sm./Lg. Intestine
  • Rectum Anal Canal
  • Teeth Tongue
  • Salivary Glands
  • Pancreas
  • Liver Gallbladder
  • Appendix

6
RESPIRATORY SYSTEM
  • STRUCTURES
  • Nose/nasal cavity
  • Pharynx
  • Larynx
  • Trachea
  • Bronchi
  • Bronchioles
  • Lungs
  • Alveolar ducts
  • Alveolar sacs
  • Alveoli
  • FUNCTIONS
  • warms, moistens, filters air
  • ensures that oxygen is supplied to the body and
    carbon dioxide removed from the body

7
CARDIOVASCULAR SYSTEM
  • STRUCTURES
  • Blood
  • RBCs, WBCs, platelets, plasma
  • Heart
  • Blood Vessels
  • Arteries, veins, capillaries
  • FUNCTIONS
  • Transportation of blood (and therefore, oxygen,
    carbon dioxide, nutrients, hormones, etc.)
  • Regulation of body temperature
  • Immunity (defense)

8
LYMPHATIC SYSTEM
  • STRUCTURES
  • Lymph vessels, nodes, fluid
  • Thymus
  • Spleen
  • Bone Marrow
  • Tonsils
  • FUNCTIONS
  • Collects fluid lost by the blood and returns it
    to the circulatory system
  • Immunity (defense)

9
EXCRETORY SYSTEM
  • STRUCTURES
  • Skin
  • Lungs
  • Kidneys
  • Bladder
  • Ureters
  • Urethra
  • FUNCTIONS
  • Excretes waste products from the body
  • Maintains water, electrolyte, and acid-base
    balance

10
ENDOCRINE SYSTEM
  • STRUCTURES
  • Pituitary Gland
  • Pineal Gland
  • Hypothalamus
  • Thyroid Gland
  • Parathyroid Gland
  • Thymus
  • Adrenal Glands
  • Pancreas
  • Reproductive Organs
  • FUNCTION
  • Regulates activities of the body by producing
    hormones, which travel though the bloodstream,
    exerting their influence on target cells

11
REPRODUCTIVE SYSTEM
  • STRUCTURES
  • Male
  • testes
  • vas deferens
  • prostate
  • scrotum
  • penis
  • Female
  • ovaries
  • uterus
  • fallopian tubes
  • vagina
  • vulva
  • mammary glands
  • FUNCTIONS
  • Produces, stores, nourishes, and releases gametes
  • Development, nourishment, and birth of offspring
