because you muscles need more blood so the heart pumps more blood
The Circulatory System circulates blood throughout the body. This blood has red blood cells that carry oxygen. When you are exercising, your heart beats faster to get more oxygen to the cells. This lets the blood travel faster, delivering more oxygen, which when received by cells is used by the mitochondria (the energy source of cells) to produce energy.

Aves (birds) have a closed circulatory system (meaning that the blood never leaves the network of blood vessels; result: faster ATP production, faster excretion of metabolic waste, faster nutrition to cells, etc.)
it makes your blood vessels pump faster and oxygen flow faster
In a single circulatory system blood is pumped from the heart to the gas exchange organ and the to the rest of the body. In a single circulatory system low blood pressure is maintained. Blood travels to organs more slowly. In a double circulatory system blood is pumped from the heart to the gas exchange organ and again to the heart and from the heart the blood is pumped to the rest of the body. In a double circulatory system high blood pressure is maintained as blood must be pumped at a faster rate to the parts of the body. blood travels more faster to organs Animals with single circulatory systems, e.g:Fish Animals with double circulatory systems, e.g:Humans
Well,circulatory system is made up of BLOOD and heart.
no
Circulatory System has blood.
cardiovascular, circulatory and respiratory.
circulatory system because blood flows through your veins
A closed circulatory system
The circulatory system consists of the heart and blood vessels.
