Flashcards in Biology Exam Deck (65):
What is atrophy
wasting away of body tissue or an organ, especially as a result of the degeneration of cells.
What is hypertrophy
An enlargement of an organ or tissue in response to an increase in the size of its cells
What is hyperplasia
the enlargement of an organ or tissue caused by an increase in the reproduction rate of its cells, often as an initial stage in the development of cancer.
What is metaplasia
abnormal change in the nature of a tissue
What is dysplasia
the presence of cells of an abnormal type within a tissue, which may signify a stage preceding the development of cancer
What is apoptosis
the death of cells which occurs as a normal and controlled part of an organism's growth or development
What is necrosis
the death of most or all of the cells in an organ or tissue due to disease, injury, or failure of the blood supply.
Define and describe Pharmacodynamics in detail
Pharmacodynamics is the branch of pharmacology concerned with the action of drugs on the body or on microorganisms within or on the body; and how the drug binds to receptors.
Define and describe Pharmacokinetics in detail
Pharmacokinetics is the scientific study of how the body processes drugs and is normally broken down into 4 stages: Absorption, Distribution, Metabolism and excretion.
What is Bioavailability
The proportion of the administered dose which reaches the systemic circulation.
What is Therapeutic Range or Therapeutic index
The difference between the level of a drug in the blood to be effective and the level where the drug becomes toxic.
What is the definition of commensal microorganisms
A microorganism that lives harmlessly (usually) on the skin
What is Aetiology
The scientific study of the causes of disease.
