4: Pathophysiology Flashcards
Study of the disease and its causes.
Pathology
The physiology of disordered function.
Pathophysiology
A decrease in cell size resulting from a decreased workload.
Atrophy
An increase in cell size resulting from an increased workload.
Hypertrophy
An increase in the number of cells resulting from cell division caused by an increased workload.
Hyperplasia
Cell division with division of the nucleus; each daughter cell contains the same number of chromosomes as the mother cell. The process by which the body grows.
Mitosis
Replacement of one type of cell by another type of cell that is not normal for that tissue.
Metaplasia
A change in cell size, shape, or appearance caused by an external stressor.
Dysplasia
Oxygen difficiency.
Hypoxia
A blockage in the delivery of oxygenated blood to the cells.
Ischemia
The constructive phase of metabolism in which cells convert nonliving substances into living cytoplasm.
Anabolism
The destructive phase of metabolism in which cells break down complex substances into simpler substances with release of energy.
Catabolism
Swelling of a cell caused by injury to or change on permeability of the call membrane with resulting inability to maintain stable intra- and extracellular fluid and electrolyte levels.
Cellular swelling
Response in which an injured cell releases enzymes that engulf and destroy itself one way the body rids itself of damaged and dead cells.
Apoptosis
Cell death; a pathological cell change.
Necrosis: (Coagulative, liquefactive, caseous, Fatty)
The liquid part of the blood.
Plasma
Red blood cells which contain hemoglobin, which transports oxygen to the cells.
Erythrocytes
White blood cells, which play a hey role in the immune system and inflammatory (infection fighting) responses.
Leukocytes
Platelets, which are important in blood clotting.
Thrombocytes
Substances such as proteins or starches, consisting of large molecules or molecule aggregates that disperse evenly within a liquid without forming a true solution.
Colloids
The percentage of the blood occupied by red blood cells is called?
Hematocrit
A protein commonly present in plant and animal tissues.
Albumin:
(albumin works to maintain blood pressure and probides colloid osmotic pressure which prevents plasma loss from the capillaries)
