3.1 Tolerance Limit of organisms Flashcards
What is tolerance limit?
The minimum and maximum amounts of any given factor a species can tolerate.
What is tolerance range?
The difference between the minimum and maximum tolerance limits.
What is Thermoregulation?
The process by which humans and other animals maintain an internal temperature within tolerance limit.
What is osmolarity?
The relative concentrations of water and solutes in cells and tissues.
What is osmoregulation
The process by which humans and other animals maintain osmolarity within tolerance limits.
What does it mean if someone is hypoglycemic?
It means that their glucose levels are below tolerance limit and have difficulty functioning due to cells not receiving enough glucose to maintain respiration.
What does it mean if someone is hyperglycemic?
It means that their glucose levels are above tolerance limit, resulting in excessive urination, thirst and hunger.
Why is glucose important for respiration?
As it is the primary substrate for respiration in animals and most other living things.
How does CO2 relate to the body?
It is a product of aerobic respiration in tissue cells that diffuses into the blood.
Is the CO2 concentration below or above tolerance limit when hypocapnia and respiratory alkalosis occur?
Below tolerance limit.
Is the CO2 concentration below or above tolerance levels when hypercapnia and respiratory acidosis occur?
Above tolerance limit.
What is chemoregulation?
The regulation of blood pH which changes due to the presence of absence of respiratory CO2 in the blood.
What is the equation of aerobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
What is the tolerance range of temperature for Humans?
between 36-38 °C
What happens to someone who is hypoglycemic if untreated?
If untreated may lose consciousness.
