3 parts of an atom
Proton- positive; in nucleus
Neutron- neutral; in nucleus
Electron- negative; outside nucleus
3 needs of living things
Food, water, oxygen, constant temperature
Amount of matter
Mass
Anything that has mass and volume
Matter
Approximately equal to the total of protons and neutrons
Atomic weight
Assemblage of all other groups of matter
Organism
Atoms that have gained or lost electrons and have a electrons and have a electrostatic charge
Ion

Cartilage cells
Chondrocytes
Cavity that contains the heart
Mediastinum
A chemical change caused by the breaking, forming or sharing bonds
Reaction
Cell parts:
Clear jelly like fluid in the cell that holds the organelles and it is the site for many chemical reactions
Cytoplasm
Combinations of proteins and carbohydrates that make fingernails and toenails
Glycoproteins
Combining two or more substances into a new substance
Synthesis
Compounds that contain carbon, hydrogen, and oxygen, and nitrogen
Proteins
Types of solutions:
The concentration of solutes inside the cell is the same as the concentration outside of the cell
Isotonic solutions
Types of solutions:
The concentration of solutes outside the cell is greater than the concentration inside of the cell
HypERtonic solution
Types of solutions:
The concentration of solutes outside the cell is lower than the concentration inside of the cell
HypOtonic solution
Cell parts:
Contains digestive enzymes to break down excess or worn out cell parts
Lysosomes
Cell parts:
Contains enzymes that are catalysts for liver and kidney functions
Peroxisomes
Cell parts:
Contains DNA for the cell
Chromatin
Cell parts:
The control center for the cell, it controls all of the activities of the cell
Nucleus
Types of systems:
Control/regulation of other systems
Nervous
Controlled by conscious thought
Voluntary

Matrix
Is one of the involuntary muscles
Cardiac or smooth muscles
Cell parts:
It controls what goes into and out of the cell
Cell membrane
Light and dark bands in skeletal muscle
Striations
A liquid droplet taken into the cell
Pinocytosis
List 2 characteristics of living things
Respond and reproduce
Located near blood vessels and release heparin and histamine
Mast cells
Lymph nodes, spleen, thymus, and tonsils
Lymphatic
Major component of blood and other body fluids
Water
Cell parts:
Makes proteins; they are sometimes called protein factories
Ribosomes
Makes up about 2/3 of the body’s weight
Water
Type of tissue:
The matrix is in layers
Bone
Means more than one layer
Stratified
Cell parts:
Modifies the proteins in the cell and sends them to correct organelle
Golgi apparatus
The molecules are bonded to a carrier molecule
Receptor mediated
Molecules are forced to move from higher pressure areas to lower pressure areas
Filtration
Most common, large star shaped cells that produce fibers in the matrix
Fibroblasts
