* Faster heart rate - pumps more blood around your body. Your blood carries oxygen which is needed by muscles for aerobic respiration. * Faster breathing rate - allows more oxygen to enter the blood. * Deeper breaths - more volume per breath relatively, so that muscles get as much as possible in order to respire aerobically.

Why do you breathe faster during exercise than during sleep?
Exercise places greater oxygen demands on the body, therefore signaling the respiratory center to increase the rate of respiration in order to increase the oxygen supply to the body's muscles and other tissues.
Does blood flow increase during exercise?
Yes, blood flow increases during exercise to deliver more oxygen and nutrients to the muscles and remove waste products.
Does blood pressure increase during exercise?
Yes, blood pressure typically increases during exercise as the heart pumps more blood to deliver oxygen and nutrients to the muscles.
What can the breathing rate increase to during exercise?
During exercise, the breathing rate can increase to around 40-60 breaths per minute or even higher depending on the intensity of the exercise and individual fitness level. This increase in breathing rate helps to supply more oxygen to the muscles and remove carbon dioxide from the body.
How does exercise increase blood oxygenation?
During aerobics exercise, lungs take in air and transfer oxygen to the blood, which is then pumped by the heart to the muscles that need it.
How does breathing change during exercise and what factors influence these changes?
During exercise, breathing rate and depth increase to supply more oxygen to the muscles. Factors that influence these changes include the intensity of the exercise, the body's oxygen demand, and the level of carbon dioxide in the blood.
Why does oxygen decrease after exercise and carbon dioxide increase?
During exercise, your body uses more oxygen to produce ATP for energy. This leads to a decrease in oxygen levels in the blood. As a byproduct of this increased oxygen consumption, carbon dioxide is produced and accumulates in the blood, leading to an increase in carbon dioxide levels.
Why does heart beat increase during exercise?
Because the heart has to pump more oxygen than usual to your muscles
Why does eRV decrease during exercise?
Inspiratory Reserve Volume is the excess volume above the tidal volume that can be inspired. During exercise, there is an increase in demand for oxygen which leads to a decrease in IRV.
Why does pulse rate increase during aerobic exercise?
Your heart has to beat faster to circulate your blood which carries oxygen to cells. During exercise your cells need more oxygen (the ones being used at least) so your heart must provide them with more oxygen, hence the faster heart rate.
Why does lung volume increase?
The lung volume that increases with exercise is vital capacity. When you exercise regularly, your body is more efficient at transporting and using oxygen, making vital capacity marginally bigger and exercise less difficult than someone who is out of shape.
Does partial pressure of oxygen increase during exercise?
Yes, during exercise, the partial pressure of oxygen in the blood can increase due to increased ventilation and blood flow, allowing more oxygen to be delivered to working muscles. This helps to meet the increased oxygen demand during physical activity.
