Organ Systems Flashcards
Integumentary system
Forms the external body covering
Composed of the skin,sweat glands, oil glands, hair and nails
Protects deep tissues from injury and synthesizes vitamin D
Skeletal system
Composed of bone, cartilage, and ligaments Protects and supports body organs Provides the framework for muscles Site of blood cell formation Stores minerals
Muscular System
Composed of muscles and tendons
Allows manipulation of the environment, locomotion, and facial expression
Maintains posture
Produces heat
Nervous System
Composed of the brain, spinal column, and nerves
Is the fast-acting control system of the body
Responds to stimuli by activating muscle and glands
Organ Systems
Cardiovascular Lymphatic Respiratory Digestive Excretory Reproductive Endocrine Muscular Nervous Integumentary Skeletal
Digestive and respiratory Systems
In contact with the external environment take in nutrients and oxygen
Nutrients and Oxygen
Distribute by the blood
Urinary and Respiratory Systems
Metabolic wastes are eliminated
Necessary life functions
Metabolism
Excretion
Reproduction
Growth
Homeostasis
The ability to maintain a relatively stable internal environment in an ever-changing outside world
Internal environment of the body is a dynamic state of equilibrium
Chemical, thermal and neural factors interact to maintain homeostasis
Homeostatic control mechanisms
The three independent components of control mechanisms are
-receptor
control center
effector
