Purple Group Cycle 4 Week 5 Year 2
Digestion
Liver
It takes the raw materials absorbed by the intestine
It breaks down and secretes many drugs.
It processes nutrients absorbed from the small intestine
Stomach
The stomach is a hollow organ
Cells in the lining of the stomach create a strong acid
holds food while it is being mixed with enzymes
Gallbladder
releases bile into the duodenum
helps absorb and digest fats
The gallbladder stores and concentrates bile
Esophagus
receives food from your mouth
Located in your throat
esophagus delivers food to your stomach
Colon
Stool is stored in the sigmoid
waste left over from the digestive process, is passed through the colon
6-foot long muscular tube that connects the small intestine to the rectum
Mouth
Digestion starts here
The beginning of the digestive tract
Saliva in the mouth mixes with food to begin the process of breaking it down
Pancreas
It makes insulin
It puts insulin directly into the bloodstream
Enzymes in the pancreas break down protein, fats, and carbohydrates
Rectum
8-inch chamber
When anything goes into the rectum, it sends a message into the brain
receives stool from the colon
Small intestine
Contents of the small intestine start out semi-solid, and end in a liquid form
Made up of three segments
Anus
2-inch long canal
The anus is surrounded by sphincter muscles
The anus is the last part of the digestive tract
Elements
a part or aspect of something abstract, especially one that is essential or characteristic.
there are 118 elements
theories changed through time
periodic table
there are 18 groups
alkaline earth metals.

Transition Metals
Basic Metals
In the periodic table of the elements, each numbered column is a group.
to find the atomic number you have to
The number of protons in the nucleus of an atom determines an element's atomic number.

The Six Classes
Minerals
Fats
Carbohydrates
Carbohydrates is a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals
Trace Elements
Proteins
They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes
Vitamins
bonding
Ionic Bonds- Formed by an attraction between positive and negative ions. There is no charge on bonded atoms
Bonding Basics- And atom that gains one or more electrons will have a negative charge. An atom that loses one or more electrons will have a positive charge. An atom that gains or loses one or more electrons is called an ion. A positive ion is called a cat ion, and a negative ion is called an an ion.
Covalent Bonds- When atoms share one or more electrons to form a bond. Each atom is left with a complete outer shell. A covalent bond forms between two non-metals
Atoms

the symbol for the element surrounded by dots
Chemical bond
the force of attraction that holds two atoms together as a result of the rearrangement of electrons between them
valence electrons
electrons that have the highest energy level
an atom is made up of
electrons
Nucleus
Protons
netrons
How to find
netrons
Negative charge
Subtract the atomic number from the atomic mass
Protons
atomic number
electrons
The numbers of electrons in an atom is the same as the atomic number of the elements
Measuring matter
Your weight is a measure of the force of gravity on you
Volume is the amount of space that matter occupies
Volume= Length x Width x Height
mass is the measurement of the amount of matter in the object
International System of units is used to measure the properties of matter
Density relates the mass of a material in a given model
Density= Mass/volume
mass does not change with location
reactions
physical change
anything that alters the form or appearance
chemical change
a change in matter that produces a new substace
