Cellular physiology Flashcards
Fluid compartment of the body percentage
Liquid (water) =
Solid =
Liquid (water) = 60 %
Solid = 40%
Fluid compartment of the body percentage
Intracellular fluid =
Extracellular fluid =
Intracellular fluid = 40%
Extracellular fluid = 20%
Fluid inside the cell is called?
intracellular fluid
Fluid compartment of the body percentage
Blood plasma =
Interstitial fluid =
Blood plasma = 5%
Interstitial fluid = 15%
Fluid outside the cell is called?
Extracellular fluid
Which fluid in the body is in Constant motion?
(due to circulation)
Extracellular fluid
In steady-state balance, what is Set point?
The normal range
Intracellular fluid contains?
Organelles
Protein
Other macromolecules
What is homeostasis?
Maintenance of nearly constant conditions in the internal environment of the body
Extracellular fluid contains large amounts of? (ions, etc)
Na, Cl, HCO3, other nutrients,
Fatty acids, Amino Acids
Abundant ions in the intracellular fluid
K
Mg
PO4
Examples of waste products in the extracellular fluid
Urea, Carbon dioxide
Lactic Acid, Creatinine
In steady-state balance, what is Sensors?
aka sensory organs
They detects changes or deviations from the set point and forms message or impulses for information regarding the changes
In steady-state balance, it executes the command or action to change or control the deviations from the set-point
Effector organs
In steady-state balance, it is your ability to respond to a stimuli whether you have high or low sensitivity
Sensitivity of the system
