Because your body requires more oxygen and to get this it needs more air to pass through the lungs.
If you use them more as in exercise your lungs will get used to inflating more when you breathe and they will transfer more oxygen into your bloodstream so your heart wont need o send as much blood to your muscles for respiration.
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
The lungs expand to take in more air while you breathe heavy and breathing more then normal day-to-day things like cleaning the house washing the dashes etc.
When you do cardio respiratory exercises, you enable more blod flow and you exercise the heart. The breathing in respiratory exercises also cleanse the breathe and helps you have more oxygen in the body.
No. Cardiovascular exercise, also known as aerobic exercise, causes you to breath more.
Mrsa on the skin is mild compared to the bloodsteram due to in the bloodstream it can affect more parts of the body like the lungs, urinanry tract and can infect open wounds.
Because during exercise more oxygen is required , so more blood is pumped to meet the requirement.
If you exercise 3-4 days a week, your lung capacity grows allowing you to exercise for longer periods of time. When you do an aerobic exercise, your heart and lungs work harder to get more oxygen around the body. Your lungs take oxygen in and then pass it on to your heart which then passes the oxygen onto your blood vessels to circulate the oxygen around the body. The oxygen is usually taken to the muscles in the limbs (Arms and Legs) to help keep them moving.
This allows the maximum possible amount of air to be inhaled, allowing more oxygen to enter the lungs and bloodstream.
False - If you are exercising, you are breathing more.
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.
