What does persistent diffuse uptake mean on a bone scan?
There is an increased level of metabolic activity of the bone throughout the body.
What is metabolic activity?
Metabolic activity is the activity in which the chemical transformations occur within the cells of living organisms. Metabolic activity is used to maintain an organisms life.
What does physiological increased uptake mean in a bone scan?
There is metabolic activity in the bone at levels expected through normal (physiologic) processes.
What is metabolic activity in a cell?
Metabolic activity is the constant flow of molecules through metabolic pathways that maintains an organism's life.
What is bio-activity?
metabolic activity of living organisms
What is an organisms chemical activity called?
metabolic activity
What is useful for viewing metabolic activity?
PET
Name three factors that can trigger vasoconstriction or vasodilation?
Can be triggered by the brain in response to changes in blood pressure. Can be triggered by increased metabolic activity like exercise and can be triggered by Alcohol and nicotine.
Which of the following is not used to determine metabolic activity?
turbidity
Where does most of the metabolic activity in a cell occur?
Most of the metabolic activity in the cell occur in the cell's cytoplasm, specifically in the mitochondria in eukaryotic (not bacterial or archaeal) cells.
What metabolic activity in plants produces sugars?
photosynthesis
Increased respiration due to increased activity is a homeostatic mechanism mainly due to?
Increased activity increases CO2 levels which are decreased by increased respiration and a normal pH maintained.
