# data[].attributes.body
The heart pumps more blood short term whilst exercising which means more oxygen and more energy

# data[].attributes.body
muscles receive more oxygen

# data[].attributes.body
Muscles fatigue and become sore due to the build up of lactic acid from the cells becoming oxygen deficient.

# data[].attributes.body
Muscles receive more oxygen and blood. Muscles increase in temperature. Muscles get more flexible.

# data[].attributes.body
muscles receive more oxygen and blood allowing for more energy output when exercising

# data[].attributes.body
Breathing rate increases and breathes are deeper - more oxygen taken in. This is because the cells and muscles need more oxygen to generate energy, and therefore the rate of gas exchange in the alveoli / capillaries increases.

# data[].attributes.body
Breathing rate increases.

# data[].attributes.body
Muscles receive more blood and oxygen and increase in temperature

# data[].attributes.body
Breathing rate increases and the amount of air taken in for each breath increases

# data[].attributes.body
Increased oxygen diffusion rate

# data[].attributes.body
Chest cavity enlarges.

# data[].attributes.body
Heart pumps harder/faster so oxygenated blood can flow through the body faster allowing muscles to have more energy

# data[].attributes.body
LUNgs can breath in and out a greater volume of air

# data[].attributes.body
The lungs can breathe in and out a greater volume of air, and with it oxygen. Increase vital capacity. Increased oxygen diffusion rate.

# data[].attributes.body
heart gets stronger and can pump more blood around the bod

# data[].attributes.body
Heart contracts more often increased heart rate
