An individual living thing
Contains skin, hair, fingernails and glands; protects the body, regulates body temperature, makes vitamin D and detects sensations
Contains bones, joints, and cartilage; supports and protects the body, attaches to muscle to aid in movement
Contains muscles; creates movement, posture, and body heat

Contains hormones and glands that produce them; regulates body activities
Contains blood, heart, and blood vessels; Pumps blood throughout the body to carry oxygen and nutrients
Contains lymph, vessels, spleen, thymus, lymph nodes, and tonsils; filters blood, protects against disease-causing microbes
Contains lungs, pharynx, larynx, and trachea; transfers oxygen and carbon dioxide between the body and environment
Contains gastrointestinal tract and accessory organs; breaks down of food and absorbs nutrients
Contains gonads and associated organs; produce gametes that unite to form a new organism
Contains kidneys, ureters, bladder; produces, stores, and eliminates urine
All of the chemical reactions that occur within an organism.
Biological processes which primarily break down large storage and other chemicals, often releasing energy in the process.
the building of complex organic molecules from simpler ones
Process by which organisms maintain a relatively stable internal environment.
A physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change.
A primary mechanism of homeostasis, whereby a change in a physiological variable triggers a response that counteracts the initial change.
Any abnormality of structure or function
Specific term for an illness characterized by a recognizable set of signs and symptoms
Subjective changes in body functions that are felt by the patient but not apparent to the observer (Ex. pain, nausea, anxiety)
Objective changes that a clinician can observe and measure (Ex. fever, high blood pressure, rash)
A standard position in which the body is facing forward, the feet are parallel to each other and the arms are at the sides with the palms facing forward.
Toward the head, or the upper part of a structure
Away from the head, or the lower part of a structure
Nearer to or at the back of the body

Away from the surface of the body
A positively charged particle in the nucleus of an atom
Electrically neutral particle that has the same mass as a proton and is found in an atom's nucleus.
A subatomic particle that has a negative charge and almost no mass
A charged atom
A chemical bond that involves sharing a pair of electrons between atoms in a molecule
Formed when one or more electrons are transferred from one atom to another
A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule.
A chemical reaction that releases energy
A reaction that requires energy
Chemical compounds that speed up chemical reactions by lowering the activation energy

A double stranded nucleic acid that forms the genetic code in the nuclei of body cells and regulates most of the cell's activities
A usually single-stranded nucleic acid that functions in protein synthesis
the organic process whereby the DNA sequence in a gene is copied into mRNA
Decoding of mRNA message into a polypeptide chain.
A selectively-permeable phospholipid bilayer forming the boundary of the cells
Control center of the cell
A property of biological membranes that allows some substances to cross more easily than others.
Movement of molecules from an area of higher concentration to an area of lower concentration.
Diffusion of water through a selectively permeable membrane
Movement of specific molecules across cell membranes through protein channels
Energy-requiring process that moves material across a cell membrane against a concentration gradient
A transport protein in the plasma membrane of animal cells that actively transports sodium out of the cell and potassium into the cell
Cellular uptake of biological molecules and particulate matter via formation of new vesicles from the plasma membrane.
Process by which a cell releases large amounts of material
An organelle that contains the centrioles and organizes microtubules during mitosis
Organelles at which proteins are synthesized.
Covered in ribosomes and is responsible for the synthesis and transport of proteins and glycoproteins.
ER that doesn't contain ribosomes; involved in lipid synthesis and breaking down toxic substances and stores calcium
Organelle that modifies and sorts proteins

Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals
An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
Splicing of RNA transcripts from the same gene in different ways, each of which produces a distinct protein
stage of interphase in which cell grows and performs its normal functions
A nondividing state in which a cell has left the cell cycle.
Cell grows and preps for mitosis
Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases
Mitosis (the division of DNA) and cytokinesis (the division of cytoplasm and other cellular material) occurs
Centrioles move away from each other pushed towards seperate ends, Nucleur membrane disintergrates,. chromotin form chromosomes Longest phase
