Hypothermia
Prolonged exposure to cold temperatures, Cold water immersion, Inadequate heating, Medical conditions, Alcohol and drug use
What are causes of hypothermia
This term describes the body's condition when it cannot dissipate heat effectively, leading to an abnormally high body temperature
What is hyperthermia
This condition results from an imbalance between water intake and output, leading to too little water in the body
What is dehydration
What is the part of the brain that controls thermoregulation
What is the hypothalamus
What percentage of the body is composed of water
What is 60%
Shivering, Vasoconstriction, Increased metabolic rate
What are temperature-rising mechanisms
his severe form of hyperthermia can occur during intense physical activity in hot environments and requires immediate medical attention
What is heatstroke
These organs play a vital role in maintaining water balance by filtering blood and adjusting the volume and composition of urine
What are the kidneys
The four major processes of thermoregulation
What is, sweating, shivering, vasoconstriction and vasodilation
What is the normal body temperature
What is 36.5–37.5°C
Shivering, Cold, pale skin, Fatigue and drowsiness, Slurred speech, Clumsiness and lack of coordination, Confusion and memory loss, Slow, shallow breathing, Weak pulse, Loss of consciousness
What are symptoms of hypothermia
This is the body's primary mechanism for cooling itself down, which can become insufficient in extreme heat conditions, leading to hyperthermia
What is sweating
This term refers to a state where the intake of water matches the output, maintaining a stable water balance in the body
What is water equilibrium or homeostasis
This protects the organs from extreme temperature changes
What is brown adipose tissue
The condition in which there is too much water in the body due to excess consumption of liquids or other factors
What is overhydration
This part of the body is typically affected first in cases of hypothermia, leading to numbness and potential frostbite
What are the extremities
This group of individuals is particularly vulnerable to hyperthermia due to their impaired ability to regulate body temperature
Who are the elderly
Water produced as a by-product of dehydration synthesis and aerobic respiration
What is metabolic water
This gland, situated atop each kidney, produces hormones involved in both thermoregulation and water balance regulation, such as aldosterone
What is the adrenal gland
This physiological response in mammals involves the contraction of blood vessels near the body surface to conserve heat when exposed to cold temperatures
What is vasoconstriction
The body's core temperature drops below this critical point in severe hypothermia, often resulting in unconsciousness
What is 28 degrees celsius
The most common symptoms of heat exhaustion
What is profuse sweating
This hormone, released by the posterior pituitary gland, helps regulate water balance by increasing water reabsorption in the kidneys
What is antidiuretic hormone (ADH)
These specialized cells in the skin help regulate body temperature by constricting or dilating blood vessels in response to changes in environmental temperature
what are thermoreceptors
What is Piloerection
