Detailed explanation-1: -Faster heart contractions. This leads to an increased heart rate and increased circulation, which gets oxygenated blood to your muscles quicker.
Detailed explanation-2: -Long-term exercise causes the heart and lungs to become more efficient as your cardiovascular training increases. The heart’s stroke volume, which is the amount of blood pumped with each beat, will increase. Every time the heart beats, blood is ejected from the left ventricle and out into the arteries.
Detailed explanation-3: -When the muscles start to work, they need more oxygen so the respiratory system responds by getting more oxygen into the lungs. The blood carries greater amounts of oxygen and the heart responds to pump more oxygenated blood around the body. Immediate effects can be visible in hot, sweaty and red skin.
