The Structure of Living Things
The Structure of Living ThingsUnit 8 Any living thing
OrganismA body part that is made up of smaller parts that work together to do a certain job. Organ
A group of organs that work together to do a job for the body.
Organ System
The organ in the human body that processes information. BrainThe human bodys largest organ that covers the outside of the body.
Skin
A hard organ that has a spongy layer inside that may help support the body or protect other organs. BonesAn organ made of bundles of long fibers that can contract and work with bones to help you move.
Muscles
A hard outer covering, found in many types of animals, that supports and protects the body. Exoskeleton The large organs that supports the respiratory system that brings oxygen from the air and into the body and releases carbon dioxide.
Lungs
A muscular organ that pumps blood through the rest of the circulatory system. HeartA bag like organ in which food is mixed with digestive juices and squeezed by a muscle.
StomachA large organ that makes a digestive juice called bile. Liver
A large organ that makes digestive juice and insulin.
Pancreas
Organs in the human excretory system that removes waste materials for the blood. KidneyOrgan in the excretory system that stores and releases urine.
Bladder
The nervous system is made up of these tiny cells.Aids in passing information to the brain. Nerve CellsChains of nerve cells that carries information to and from the brain.
Nerves
A rope like bundle of nerves that runs along your backbone.Main pathway for information to travel to and from the brain. Spinal CordThe back of the eye that detects light.
Retina
Taste BudsBumps on the tongue that sense chemicals in food. Passes vibrations (sounds) to tiny hairs attached to nervesPart of the ear
Cochlea
The inner layer of the skin. It contains hair follicles, sweat glands, bloods vessels, and nerve endings. DermisThe outer layer of the skin.It is thin in some places and thick in others.
Epidermis
Connect bones to joints.LigamentsA place where two or more bones meet.Some joints move and others do not (skull)
Joint
Provides cushion to the ends of bones and forms flexible parts like ears and nose. CartilageAllows air to pass from your nose to your lungs.
Trachea
Brings air from the trachea to the lungs. BronchiAllows air to flow from the bronchi to the aleveoli.
Bronchioles
Tiny sacs that make up most of the lungs. AlveoliCarry oxygen throughout your body
Red Blood Cells
Fight foreign objects (viruses, diseases, bacteria, etc)White Blood CellsCarries nutrients and blood cells throughout the body.
Plasma
Stops bleeding by sticking together and forming clots.
Think scapsPlatelets
Are blood vessels that carry blood away from the heart to different parts of the body. ArteriesBlood vessels that brings blood back to the heart from the lungs and body.
Veins
Are tiny blood vessels with very thin walls that connects arteries and veins. Oxygen and nutrients can pass through the thin walls to the body.CapillariesA long tube that begins in your throat.It moves food from your mouth to your stomach.
Esophagus
Long tube that digests food and absorbs nutrients your body needs from the digested food. Anything not absorb is sent to the large intestines. Small IntestineA large tube that soaks up water and mineral and leaves only waste. Solid waste passes out of your body.
Large Intestines
Is a way to measure how much energy your body will get from food.CaloriesA source of energy
Carbohydrates
Builds muscleThe only source of energy your brain uses.ProteinsUsed to make important chemical signals and to store energy.
Fats
Contains information about the food you eat.Nutrition LabelIs toxic and made of broken down protein.
Ammonia
Takes urine from the kidneys to the bladder. UretersA small tube that takes the urine from the bladder to outside the body.
Urethra
