Maintain the balance
Thermoregulation, blood-glucose levels, and hydration status are all examples of this.
Negative feedback loops
The storage form of glucose.
Glycogen
The maximum amount of oxygen your body can use
VO2 max
The initial freezing of the superficial skin tissue.
Frostnip
Blood circulation between the heart and the lungs.
Pulmonary circulation
The brain, brainstem, and spinal cord are all part of this
The central nervous system
The widening of blood vessels, caused by the relaxation of the smooth muscle in the wall of the blood vessel.
Vasodilation
The respiratory system enables the exchange of gases between the body and ____________.
External environment
The hearts response to heat acclimatization includes a ________ heart rate and an __________ stroke volume.
Decreased heart rate
Increased stroke volume
Blood redistributes to this tissue type during exercise.
Muscle tissue
Activates the "fight-or-flight" response
Sympathetic nervous system
A hormone, secreted by the pituitary gland, that regulates the fluid and electrolyte balance in the blood by reducing urine production.
Antidiuretic hormone
Air moved in a single breath
Tidal volume
A desensitization of the normal response to cold
Habituation
Cardiovascular capacity generally does this with age
declines
The activation of this system results in slow but long-term changes in the body.
Endocrine system
Specialized cells located in muscles, tendons, joints, and the inner ear that provide information about body position, muscle length and tension, position and movement of joints, and help maintain balance.
Proprioceptors
Influences respiratory efficeiency
Fitness level
Heat acclimation protocols improve this homeostatic function.
Thermoregulation
Blood pumped per beat
Stroke volume
Hormones that are fat-soluble and can easily pass through cell membranes to interact with the receptors and elicit a response. Examples include testosterone, Estrogen (oestrogen), and progesterone.
Steroid hormones
The total volume of air breathed in one minute, calculated by multiplying tidal volume by respiratory rate.
Minute ventilation
Total air breathed per minute
Minute ventilation
These 3 factors influence your body's ability to cope with cold exposure.
Body composition, body size, and training status
Platelets, erythrocytes, leukocytes, and plasma
Components of blood
