Homeostasis - Tolerance Limits Of Organisms

Organisms —— most effectively within their ——

Organisms survive most effectively within their tolerance

factors for which organisms have a tolerance limit include..

Body temperature, CO₂ concentration, H₂O availability and blood glucose levels

conditions outside —— can have serious impacts on an ——, where the body begins to —— and ——

conditions outside the tolerance limit can have serious impacts on an organism, where the body begins to dysfunction and dysregulate

the tolerance limit refers to….

the tolerance limit refers to the conditions in which the organisms can withstand

the body temperature range for which humans can function most effectively within is…

the body temperature range for which humans can function most effectively within is 36-38 degrees celcius

hypothermia refers to…

hypothermia refers to low body temperature

hyperthermia refers to…

hyperthermia refers to high body temperture

the body temperture is regulated by…

the body temperature is regulated by the brain

hypotonic solution refers to… where cells——

hypotonic solution refers to low solute concentration, where cells begin to swell, and potentially rapture

hypertonic solution refers to… where cells——

hypertonic solution refers to high solute concentration, where cells begin to shrink, and potentially not function properly

acidosis is a condition that occurs when…

acidosis is a condition that ocurs when there is a high concentration of CO₂ in the bloodstream, leading to a decrease in blood pH levels

alkalosis is a condition that occurs when…

alkalosis is a condition that occurs when there is a low concentration of CO₂ in the bloodstream, leading to an increase in blood pH level.

blood pH is regulated by…

blood pH is regulated by the brain

high amounts of CO₂ can lead to ——, while low amounts of CO₂ can lead to ——

high amounts of CO₂ can lead to acidosis, while low amounts of CO₂ can lead to alkalosis

in the human body, the tolerance limit for blood pH is between ——

in the human body, the tolerance limit for blood pH is between 5% and 7%

hypoglycemia is a condition that occuers when—-

hypoglycemia is a condition that occurs when glucose levels in the blood are too low,

hyperglycemia is a conditon that occurs when—-

hyperglycemia is a conditon that occurs when glucose levels in the blood are too high

in the human body, the blood glucose tolerance limit is between

in the human body, the blood glucose tolerance limit is between 75-95mg/dL (dL = 100mL)

if the blood glucose level is beyond the tolerance limit, body can become ——

if the blood glucose level is beyond the tolerance limit, the body can become unconscious

the blood glucose levels are regulated by the hormones —— and ——, where —— increases the blood glucose level, and —— decreases the blood glucose level.

the blood glucose levels are regulated by the hormones, insulin and glucagon, where glucagon increases the blood glucose levels, and insulin decreases the blood glucose level.

state one reason why body temperature must be within its tolerance limit

If an organism body temperature goes above its tolerance limit, enzymes may begin to denature due to the extreme heat. This slows down metabolic activities as enzyme lose their structure and therefore function.

state one reason why blood glucose levels must be within its tolerance limit

if the blood glucose level where to go beyond its tolerance limit, then hyperglycemia would occur, where autoimmune diseases such as diabetes could be developed

state one reason why blood water levels must be within its tolerance limit

if the blood water levels were to rise beyond its tolerance limit, then osmolarity levels would decrease causing blood cells to swell and burst, reducing blood volume and therefore blood pressure. low blood pressure can lead to dizziness, and fainting.

state one reason why blood CO₂ levels must be within its tolerance limit

CO₂ is acidic, therefore CO₂ levels beyond the tolerance limit could lead to acidosis (low blood pH), this could lead to impaired conscious and potentially even death.
