The process of moving nutreints from the intestines into the blood stream. - ANS-What
is metabolic absorption?
Peroxiomes - ANS-What uses oxygen to remove hyrdogen atoms in an oxidative
reaction?
digestive enzymes from lysosomes - ANS-During cell injury what is released that is
capable of cellular autodigestion?
metabolism of exogenous chemicals or drugs - ANS-Cellular Injury Chpt. 2 Power Point
A nurse knows that free radicals may be produced by
The cell nuclues (DNA) - ANS-Where is the genetic info containe in the cell?
phospholipids, cholesterol, proteinsm and carbohydrates - ANS-Cell membranes
contain which major chemical components
Aldosterone, insulin, and epinephrine - ANS-What allows potassium to diffuse in and out
of cells?
The cells response to escape and protect itself from injury - ANS-What is cellular
adaptation?
Produces abnormal proliferation of abnormal cells - ANS-Which of the following
statements is correct regarding pathologic hyperplasia ?
1.) Produces abnormal proliferation of abnormal cells.
2.) Is an adaptive mechansim that enables organ regeneration?
3.) Increases cell size
4.) May occur in response to growth factors.
Abnormal changes in the size, shape, and organization of mature cells. Does not
indicate cancer. ( Can also be called atypical hyperplasia) - ANS-What is dysplasia?
reversible change in which one adult cell type is replaced by another adult cell type -
ANS-What is metaplasia?
Is metabolized via the microsomal P-450 - ANS-Which of the following is true about
alcohol (ethanol)?
, 1.) Is metabolized via the microsomal P-450.
2.) Is primarily metabolozed and excreted by the kidneys.
3.) Increases activation of methionine, an essential amino acid.
4.) Can produce hypermagnesemia with chronic use.
Cellular Adaptation - ANS-What protects the cell from injury?
oxidative stress
radicals that cause membrane damage and
mitochondrial calcium overload
Mitochondrial permeability transition pose - ANS-What causes ischemic reperfusion
injury?
Tissue transplantation
Ischemic syndromes: myocardial, hepatic, intestinal, cerebral, renal, stroke - ANS-
Mechanism of cellular injury?
- ANS-In cirrhosis, what does cholesterol have to do with the erythrocytes?
Fish and healthcare equipment - ANS-What are two major sources of mercury?
A family of molecules released from platelets (tiny pieces of cells that are found in the
blood and that help the blood clot). Forms of platelet-derived growth factor help to heal
wounds and to repair damage to blood vessel walls. They also help blood vessels grow.
Also called PDGF. - ANS-What is platelet-derived growth factor?
Cell communication is the process by which a cell detects and responds to signals in its
environment. Cells communicate through their own language of chemical signals.
Different compounds, such as hormones and neurotransmitters, act like words and
phrases, telling a cell about the environment around it or communicating messages. -
ANS-What is cell communication? How does it occur?
Gout - ANS-What does excess urate (uric acid)cause?
proteins, carbs, lipids, vitamins, and minerals. - ANS-What essential nutrients are
required for normal cell function?
(Phagocytic cells- ability to ingest foreign particles)
Histamine
Antibodies
Lymphkines
Complement
Proteases - ANS-What are come examples of immunological and inflammatory
substances that lead to injury?
