A) additional oxygen will diffuse into the blood as carbon dioxide diffuses out of the blood in the lungs
Increases due to greater oxygen demands and a rising blood CO2 concentration (PCO2).
Your rate of breathing increases in a crowded area because there is less oxygen. This is because there are more people breathing in the oxygen.
When the breathing rate increases, more oxygen is brought into the body and more carbon dioxide is removed. This helps to meet the increased demand for oxygen by the body during physical activity or moments of stress. Increased breathing rate can also help regulate the pH balance in the blood by removing excess carbon dioxide.
(as far as I know) The reason why the breathing rate increases is because, as you exercise, your muscles require more oxygenation, in order to fulfill this, you get more oxygen by breathing more, and your heartbeat increases to deliver the oxygen faster
It increases both. The rate of cell metabolism is accelerated during fever, which increases the demand for oxygen by tissue cells. This means the heart must contract more frequently to keep up with the demand, and breathing is accelerated to increase the rate of oxygen and carbon dioxide exchange.
the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.
Your Breathing rate is increased due to the fact that your muscles are working harder then when they are at rest. This means that they need oxygen, along with sugars to complete cellular respiration. Your heart rate increases so that it can move the oxygen to the target cell in the muscles you are using quicker.
If the level of carbon dioxide increases, the repiratory centers are signaled to increase the rate and depth of breathing. This will result in the return of normal CO2 (carbon dioxide) and slows the breathing rate.
Your breathing rate increases to get more oxygen into your bloodstream, and your pulse quickens to allow the blood to get to muscles faster to deliver the oxygen. =) Alex, 17.
It slows down back to normal. Your heartbeat increases as you run, and it slows down as you slow down. Your cells don't need as much oxygen to fuel your cells when you're walking as when you're running. So, your heart doesn't pump as fast when you stop running. Therefore your lungs don't need to supply as much oxygen, so your breathing slows down.
There is an increase in the breathing rate, this is due to the demand for oxygen from the working muscles. •The Respiratory Volume increases, this is due to the increase of Tidal Volume and breathing rate whilst meeting the demand of oxygen for the working muscles.
