functions of integumentary system - protection, body temperature regulation, cutaneous sensation,
metabolic functions, blood reservoir, excretion

components of integumentary system - skin, hair, nails, sweat glands, oil glands, mammary glands

, Functions of the skeletal system - support, storage of minerals and lipids, blood cell production,
protection, leverage

components of skeletal system - All Bones, Joints, Cartilage, Ligaments

Functions of the muscular system - movement, posture, joint stability, heat production

components of muscular system - skeletal muscles

Functions of the nervous system - Generates action potentials (nerve impulses) to regulate body
activities; detects changes in body's internal and external environments, interprets changes, and

chemical composition of blood;

Components of the Urinary System - kidneys, ureters, bladder, urethra
