you're muscles need more oxygen which is carried in you're blood. this is why you breathe faster as well.
The brain, active muscles, and abdominal region produce more heat because they are more metabolically active.
While exercising, your muscles need more oxygen in order to create more energy through cellular respiration. In order to supply more oxygen, the heart beats faster so blood moves faster throughout the body.Because the muscles need more blood i them Because your muscles require more oxygen which is delivered to them through the blood stream, which is pumped to them by the heart, so the heart beats to kep up with the demand.
it depends wither they are active as athletic people have larger hearts due to the amount of blood being pumped around - men do generally have larger hearts as they are bigger then women it depends wither they are active as athletic people have larger hearts due to the amount of blood being pumped around - men do generally have larger hearts as they are bigger then women it depends wither they are active as athletic people have larger hearts due to the amount of blood being pumped around - men do generally have larger hearts as they are bigger then women
Breathing faster will only drag more oxygen into the lungs, but to get more oxygen to the muscles it has to be picked up and carried into the body by the blood. So the heart has to pump more too, tho move the oxygen from the lungs to the muscles.
When you run, your muscles are working harder than usual. They therefore need more oxygen and sugar to metabolize, in order to produce energy that they can use to do this work. Oxygen and sugar are transported by the blood, and blood is pumped by the heart.
More oxygen, for the pumped blood circle through the body and the body consumes more oxygen and carries more oxygen than it carries carbon-dioxide.
Yes.
Because during exercise more oxygen is required , so more blood is pumped to meet the requirement.
Blood is pumped throughout the body by the heart through arteries. The "Used" blood is further pumped back to the heart through veins. 'Veins' is your answer.
When you are running, your muscles are working extra hard. Therefore, they need more oxygen and glucose than normal, since it is the chemical reaction between these two that produces energy for work. The blood is pumped to the lungs for more oxygen and to the liver for more glucose. (Glucose is stored in the liver.) Blood flow to the working muscles is increased in order to deliver these two, and to carry away carbon dioxide and heat that are produced as wastes.
Your digestive system works even when you are asleep.In the morning as you go about your daily activities more blood is pumped into the parts of the body that are working very hard.For example -when you run more blood is pumped to the muscles in your hands and legs.When you go to sleep your body cuts down blood supply to other parts of the body such as hands, legs.Your body increases the the blood flow to the digestive system. During this process all the impurities and unwanted matter is removed and sent to the excretory system.
When You use A set of muscles,The blood flows to them so you can exersice longer.
