Cardiovascular drift is the increase of heart rate that occurs during long periods of exercise with little or no work load.

# data[].attributes.body
this is the condition of have a body temperature above normal 37 degrees Celsius

# data[].attributes.body
Dehydration is the lack of water in your body, this can have negative effects on your body as your body requires water to survive.

# data[].attributes.body
Thermo receptor are receptors in your body which detect an increase or decrease in heat loss

# data[].attributes.body
Thermoregulation is the way your body reduces or increases heat loss to suit your surroundings

# data[].attributes.body
it is due to the body not being able to get enough oxygen to working muscle and organs,  to prevent this you should:
- Drink a lot of water
- Eat potassium rich foods
- Acclimate
- Don't do too much physical activity

# data[].attributes.body
It is a hormone that is produced by the body, it increases the synthesis of red blood cells

# data[].attributes.body
decreased partial pressure in aveolar air, decreased diffusion gradient to capillary blood,  decreased haemoglobin and o2 association, decreased o2 transportation to muscle tissue. This leads to decreased diffusion gradient to muscle tissue and a decreased O2 supply for aerobic energy production . This means  increased breathing frequency, decreased blood volume and stroke volume and an increase in heart rate. Decreased VO2 max, aerobic capacity, intensity and duration of aerobic performance before fatigue. This can lead  hypoxia body deprived of O2 transport for tissue.

It could lead to the performer feeling isolated and it could lead to lifestyle changes that the performer is not used to.

# data[].attributes.body
partial pressure of oxygen is lower, this means that your body has to work harder compensate by increasing things like breathing rate and there for increasing oxygen diffusion. This means a higher cardiac output making your body more efficient in a higher altitude.

# data[].attributes.body
an internal expiration site is the site in which the air had contact with the outside , such as between capillaries and alveoli, oxygen moves down the pressure gradient there fore it will move from alveoli to capillaries as they have a low concentration of oxygen in capillaries and a high concentration inside the alveoli. External expiration sites are between the capillaries and the cells in tissues, this also moves along the pressure gradient to aid aerobic respiration.

# data[].attributes.body
This is the net movement of particles from an area of high concentration to and area of low concentration.

# data[].attributes.body
This is the pressure of the gas if it occupied the same volume and temperature as the mixture of gasses

# data[].attributes.body
The pressure of the atmosphere surrounding the earth.

# data[].attributes.body
this is the amount of water vapour in a given section of area

# data[].attributes.body
this is the height of the land from sea level
