What are the major organs in the Skeletal system?
Bones, cartilages, tendons, ligaments, and joints
What are the major organs in the muscular system?
Muscles attached to the skeleton
What are the major organs in the Nervous system?
Brain, spinal cord, nerves, and sensory receptors
What are the major organs in the Endocrine system?

What are the major organs in the Reproductive system?
Male: testes, prostate gland, scrotum, penis, and duct system which carries sperm to body exterior
Female: ovaries, uterine tubes, uterus, mammary glands, and vagina
What is the purpose of the Integumentary system?
Protects deeper organs from mechanical, chemical, and bacterial injury, and from drying out
Excretes salts and urea
Aids in regulation of body temperature
Produces vitamin D
What is the purpose of the Skeletal system?
Body support and protection of internal organs
Provides levers for muscular action
Cavities provide a site for blood cell formation
Bones store minerals
What is the purpose of the Muscular system?
Primary function = contract or shorten, allows locomotion, grasping and manipulation of environment, and facial expressions
Generates heat
What is the purpose of the Nervous system?
Allows body to detect changes in its internal and external environment and to respond to such information by activating appropriate muscles or glands
Helps maintain homeostasis of the body via rapid transmission of electrical signals
