SKELETAL SYSTEM Major Structures:

Bones Cartilage Ligaments Tendons

Function Support the body Protects internal organs Allows movement Stores internal reserves Provides a site for blood

cell formation

MUSCULAR SYSTEM Major Structures:

Skeletal Smooth Cardiac

Function: Works with skeletal

system to produce voluntary movement

Helps to circulate blood and move food through the digestive system

Skin Hair Nails Sweat and oil glands

Function: Serve as a barrier against

infection and injury. Helps keep body

temperature Protect against UV

radiation

RESPIRATORY SYSTEM

Major Structures: Nose Pharynx Trachea lungs

Functions: Provides oxygen needed

for cellular respiration and removes excess carbon dioxide from the body

DIGESTIVE SYSTEM Major Structures:

Mouth Pharynx Esophagus Stomach Small and large intestine rectum

Function: Converts foods into

simpler molecules that can be used by the cells of the body

Absorbs food and eliminates wastes

EXCRETORY SYSTEM

Major Structures: Skin Lungs Kidneys Urinary bladder Urethra

Functions: Eliminates wastes

products from the body in ways that maintain homeostatsis

ENDOCRINE SYSTEM

Major Structures: Hypothalamus Pituitary Thyroid Pancreas Ovaries or Testes

Function Controls growth,

development and metabolism

Maintains homeostasis

REPRODUCTIVE SYSTEM

Major Structures: Males: Testes,

epdidymis, vas deferens, urethra and penis

Females: Ovaries, Fallopian tubes, uterus and vagina

Function Produces reproductive

cells In females nurtures and

protects developing embryos

LYMPHATIC/IMMUNE SYSTEM

Major Structures: White blood cells Thymus Spleen Lymph nodes Lymph vessels

Function Helps protect the body from

disease Collects fluid lost from blood

vessels and returns the fluid to the circulatory system
