What else can I help you with?
What two things do muscles need?
nutrition and oxygen
When your active why does more blood get pumped to the muscles?
you're muscles need more oxygen which is carried in you're blood. this is why you breathe faster as well.
Do muscles need oxygen to move?
Yes
Why does heart rate increases?
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.
When your bodies get warmed up what increases to the muscles that need it?
oxygen
Why do we become short of breath?
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.
Why does the heart beat faster when exerciseing?
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.
Do muscles need oxygen to work?
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.
Why cant you run for as long if you have less oxygen in your blood?
because your blood carries oxygen to you muscles. without much oxygen blood won't be able to take lots to your muscles, and with little oxygen your muscles won't work as well and therefore you won't run as quickly :)
What happens when muscles are exercised without sufficient oxygen?
well if muscles run out of oxygen you might slow down and not breath proppely and you might also die.
Why do your pulse rate increase when you are running?
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.
How does smoking effect your muscles?
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.
