Body Systems and Disease Study Guide
Skeletal system - To support the body; to give the body shape; to work with the muscles to move the body
The skeletal system is made up of bones.
Muscular system - To maintain body temperature; to help the body move; to maintain posture
* Skeletal muscle – Voluntary; attached to the bones
* Smooth muscle – Involuntary; controls movements within the body; makes up the stomach
* Cardiac muscle - Involuntary; makes up the heart
Integumentary system – To cover and protect the body
* Skin - functions to cover the body, prevent water loss, and protect the body from infection.
Circulatory System - transports oxygen and other nutrients to cells, circulates blood through the body
* Heart - A muscular organ in the center of the chest that pushes blood throughout the circulatory system.
* Blood vessels – tubes that carry blood throughout the body
o Artery - A blood vessel with strong walls that carries blood away from the lungs.
o Capillary - A narrow blood vessel that connects arteries with veins.
o Vein - A blood vessel that carries blood back to the lungs.
Respiratory System -exchanges gases between the body and the external environment (brings in oxygen,
removes carbon dioxide)
* Trachea - A tube that carries air from the throat to the lungs.
* Lungs - Two large organs located in the chest and are the main organs of the respiratory system.
* Bronchi - The two large air tubes leading from the trachea to the lungs that convey air to and from the
lungs.
* Diaphragm - A muscular wall that expands and contracts the chest when you breathe.
Digestive System - breaks down food into nutrients the body can use and disposes of solid waste.
* mouth – chemical and mechanical digestion take place here
* esophagus – carries chewed food to the stomach
* stomach – chemical and mechanical digestion take place here.
* small intestine – most of the chemical digestion takes place here; where nutrients are absorbed
* large intestine – Water is removed from the undigested food.
* rectum – stores solid waste
* liver – produces bile
* gallbladder - stores bile
* pancreas – produces digestive juices
Urinary System - filters cellular wastes, toxins, and excess water from the body.
* Kidney – Remove wastes and extra water from the blood to form urine.
* Ureter – A tube that transports urine from a kidney to the bladder.
* Bladder – A sac-like organ that stores urine.
* Urethra – A tube that carries urine from the bladder to the outside of the body.
Nervous System - detects and responds to changes in the environment; transmits information throughout the
body.
* Brain – The main organ of the central nervous system. Controls and coordinates most of the body’s
activities.
* Spinal cord – A bundle of nerves that runs down the center of the back through the vertebrae which
protects it.
* Peripheral nerves – A network of nerves that branch out from the spinal cord and connect to the rest of
the body.
How the body systems work together:
* The urinary and digestive systems work together to bring food into your body and remove waste.
* The urinary and circulatory systems work together to clean blood and remove cellular waste.
* The circulatory and respiratory systems work together to remove carbon dioxide and supply oxygen.
* The digestive and circulatory systems work together to ensure that nutrients get to the cells of the body.
* The skeletal and muscular systems work together to help the body move.
