Anatomy
A scientific discipline that deals with the processes or functions of living things
Physiology
Basic unit of all the plants and animals
Cell
A collection of cells with similar structure and function, and the substances between the cells
Tissue
The group of organs classified as a unit because of common function, or set of functions
Organ system
Any living thing
Organism
Some of the chemical changes that occur in tissues, consisting of the breakdown of molecules to produce energy and the buildup of molecules which require energy
Metabolism
The ability of an organism to sense a change in the external or internal environment, and adjust to those changes
Responsiveness
The acquisition of specialized structures and functions different from the original structure and function
Differentiation
Existence and maintenance of a relatively constant environment within the body with respect to functions and the composition of fluids and tissues. The process by which we maintain stable internal environment.
Homeostasis
A normal range around which homeostatic variables are maintained
Setpoint
The processor regulates, most homeostatic variables, working to reduce the deviation from the setpoint
Negative feedback
The smallest particle into which an element can be divided using chemical methods. Composed of neurons, protons, and electrons.
Atom
Association between two atoms formed when the outmost electrons are transferred or shared between atoms
Chemical bond
Chemical bond resulting from the attraction between ions of opposite charge
Ionic bond
A chemical bond forms were two atoms share one or more pairs of electrons
Covalent bond
Two or more atoms, chemically combined to form the structure that behaves as an independent unit
Molecule
Separation of positive and negative ions when they dissolve in water and are surrounded by water molecules
Dissociation
Positive and negative ions that conduct, electricity and solution
Electrolyte
Processed by which atoms or molecules interact to form or brief chemical bonds
Chemical reaction
The energy currency of the cell
ATP
Substance taking part in a chemical reaction
Reactants
A substance produced in a chemical reaction
Products
State created by a chemical reaction proceeding in opposite directions at equal speed
Equilibrium
Any substance that is a proton donor or any substance that releases hydrogen ions
Acid
A chemical that resists changes in pH, when either an acid, or a base is added to a solution containing the buffer
Buffers
Protein molecules that increase the rate of a chemical reaction without being permanently, altered. And organic catalyst.
Enzyme
An organic molecule made up of one or more monosaccharides, chemically bound together sugars, and starches
Carbohydrates
Substance, composed principle of carbon, oxygen, and hydrogen. Generally soluble and nonpolar solvent. Fats and cholesterol.
Lipid
Large molecule, consisting of long sequences of amino acids linked by peptide bonds
Proteins
Major, consisting of many nucleotides chemically bound together. Dioxide ribbon, nucleic acid and ribbon nucleic acid.
Nucleic acid
Specialized part of a cell performing one or more specific functions
Organelles
Inside a cell
Intracellular
Outside a cell
Extracellular
Passive membrane transport. Movement is driven by the concentration gradient.
Diffusion
Special name for diffusion of water across the selectively permeable membrane. Water moves by osmosis from an area of high concentration to an area of low water concentration
Osmosis
Dissolve substance in a solution
Solute
Liquid that holds another substance and solution
Solvent
