It circulates to your brain, but it circulates from your heart.
The faster your blood circulates, the faster blood can get to your muscles, giving you more energy in your muscles to use those muscles. Muscle cells need oxygen to work just like any other cell.
Blood, Oxygen, Energy (Glucose)
Together! They get their energy from oxygen in the blood that circulates around the body. (the heart pumps the blood around the body)
what two systems are working together when one circulates blood and the other provides nutrients
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.
Providing energy and the regulation of blood glucose
In Englishman named William Harvey was first to describe that blood circulates by blood vessels.
There are many different kinds but possibly the most well known would be glucose, or more commonly known as sugar (C6H12O6)
Because it circulates blood.
