Why do red blood cells take oxygen to the working muscles?
Red Blood cells take oxygen to the working muscles as it is required for respiration.
How does Oxygen affect dieting?
Your working muscles can take oxygen out of the blood three times.
What do red blood cells carry to the working muscles?
Oxygen
What are the short terms on the respiratory system?
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.
What does cardiorespotaory fitness measure?
It measures the capacity of the heart, lungs, and blood to transport oxygen to the working muscles, and measures the utilization of oxygen by the muscles during exercise.
Why is anaerobic respiration more likely to be used by your body in short high-intensity workouts than in endurance exercises such as long-distance swimming?
Anaerobic respiration is repairing without oxygen, so in a sprint for example, the muscles are working so hard that even with oxygen being breathed in, it is not enough to supply the energy, so anaerobic resooration takes place to release enough energy. With long distance events, the muscles aren't working as fast or hard, s there is enough oxygen, and no oxygen debt.
What is the process where the muscles need oxygen?
if the working muscles do not have enough oxygen, then the process is anaerobic respiration where the glucose in the cells is creating lactic acid as it is not reacting with the oxygen needed like it would if the body was respiring normally then it would be aerobic respiration
How well can the circulatory system supply oxygen to working muscles during excises?
oxygen is breathed into the lungs where 'gaseous exchange' takes place, this transfers the oxygen to the blood supply (circulatory system) which already contains various substances ie. food etc. Oxygen is taken via the blood capilary network to the muscle cells 'mitchocondria' where 'airobic resperation' takes place, this involves the food being broken down using the oxygen, releasing energy to the cells and producing carbon dioxide and water as byproducts.
How does the body pass the oxygen round the body especially to the muscles?
blood takes it to the all parts of body
Why does breathing rate changes?
Because your exercising your muscles are using more oxygen. In order for your body to keep working and keep up with the amount of oxygen your body is needing, it speeds up the breathing. This gets more oxygen in and flowing to your muscles. If you muscles just relied on the amount of oxygen you got in with a normal breathing rate, you wouldn't get far.
What is the gas your muscles produce when they are working?
Carbon dioxide.This is due to the fact that muscles need oxygen to function and so uses oxygen and converts it into Carbon dioxide. Hopefully this helps!
What organ converts blood from oxygen-rich to oxygen-poor?
oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.
