NUR 303 UMaine Exam 1 With
Complete Solution
Osmosis - ANSWER a process by which molecules of a solvent tend to pass
through a semipermeable membrane from a less concentrated solution into a
more concentrated one, thus equalizing the concentrations on each side of
the membrane
Diffusion - ANSWER Diffusion is the net passive movement of particles
(atoms, ions or molecules) from a region in which they are in higher
concentration to regions of lower concentration
Hydrostatic Pressure - ANSWER the pressure at a given point in a fluid at
rest; due to the force of gravity
Endocytosis - ANSWER the intake of material by a cell from without, by
invagination of the cell membrane to form a vacuole.
Exocytosis - ANSWER a process by which the contents of a cell vacuole are
released to the exterior through fusion of the vacuole membrane with the
cell membrane.
Phagocytosis - ANSWER the ingestion of bacteria or other material by
phagocytes
Pinocytosis - ANSWER the ingestion of liquid into a cell by the budding of
small vesicles from the cell membrane.
Hypertrophy - ANSWER the enlargement of an organ or tissue from the
increase in size of its cells.
, Metaplasia - ANSWER abnormal change int he nature of a tissue
Ischemia - ANSWER an insufficient blood supply to an organ or part of the
body
Atrophy - ANSWER to decrease in size or wasting away of a body part or
tissue
Dysplasia - ANSWER abnormal growth or development of a tissue or organ
Apoptosis - death of cells that occurs as a normal and controlled part of n
organism's growth or development
Macrophages - a type of white blood cell that engulfs and digests cellular
debris, foreign substances, microbes, cancer cells, and anything else that
does not have the types of proteins specific to healthy body cells on its
surface in a process called phagocytosis
Self-antigens ANSWER any molecule or chemical group of an organism which
acts as an antigen in inducing antibody formation in another organism but to
which the healthy immune system of the parent organism is tolerant
Delayed hypersensitivity - ANSWER hypersensitivity (as in a tuberculin test)
which is mediated by T cells and in which the typical symptoms of
inflammation and induration appear in an individual previously exposed to
an antigen after an interval of 12 to 48 hours following a subsequent
exposure
Anaphylaxis - ANSWER an acute allergic reaction to an antigen to which the
