Tema 1

Question 1

CORPORAL LIQUIDS

Answer 1

intracellular: inside cells
extracellular or internal environment: where we find the cells
-intersticial
-plasma

Question 2

internal environment

Answer 2

constantly renewed by blood flow, so the communication between the external environment and cells is effective
has to be maintained in an equilibrium

Question 3

homeostasis
-values that have to be maintained

Answer 3

maintenance of the constant values of the internal envorinmnet due to the coordinated action of physiological processes

-osmotic pressure
-partial pressure of O2 and CO2
-temperature

Question 4

homeokinesis

Answer 4

capability of modifying the REFERENCE values to adapt better to different circumstances
for example: exercise and fever

It represents the dynamic equilibrium of the internal environment

Question 5

feed-back systems

Answer 5

cycle of events where a giben value or condition is monitorised and feedback is sent to the control centre, which produces a response

it is formed by 3 elements : receptor, control centre + effector

negative: opposite response to the stimulus
positive: increases the stimulus

Question 6

stimulus

Answer 6

alteration that changes the set values of a condition
