To put it simply, almost all cells in our body require oxygen to function. Oxygen is needed for the mitochondria in our cell to produce energy. Glucose is also needed in the process of producing energy.
because all cell need oxygen to get enegry
nutrition and oxygen
Yes
because you need more oxygen to be delivered to the muscle and more waste to the lungs. when you are exercising your muscles need oxygen so the blood stars pumping faster to get the oxygen to the muscles.
oxygen
Your muscles use oxygen that's extracted from the air by the lungs and transported to the muscles by the blood. When you begin to move your muscles will need more oxygen, so you need to breathe faster in order for the lungs to be able to pick up more oxygen from the air.
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
Yes, cardiac muscles cells have a very high oxygen demand, since they are constantly in motion. This is why any shortage of oxygen causes angina, or if the oxygen deprivation is long enough, it causes death of the muscle cells - what is commonly called a heart attack.
Your muscles need oxygen to work and oxygen is carried through the blood, propelled by the heart. When you run, you use muscles and your heart beats faster to increase the amount of oxygen reaching the muscles being used.
broken down energy from food.
it effects your muscles because if there is a shortage of oxygen in your body already, your muscles aren't getting the oxygen they need so they begin to become tired and cant work to the the best of their ability. for a sports performer this can be fatal because then they cant perform in their sport if their muscles can't. this is all because smoking has stopped them from getting the oxygen that they need.
Because when you work your muscles they need more oxygen, and to get more oxygen you need to breathe more often.
They should use more oxygen your muscles burn either sugar or fat, it doesnt need oxygen to burn sugar, but the by product of burning sigar is lactic acid or pruvic acid, anyway it makes your muscles ache. if you are exercising and breathing hard, then you are burning sugars. to burn fat your muscles need oxygen. The harder you work the more ogygen is required.
