The first scientist to describe that the heart circulates blood was the Arabian physician Ibn al-Nafis, in 1242 AD.
It turns from oxygenated blood to deoxygenated blood. The tissues absorb the oxygen that your red blood cells carry through diffusion through the capillary membranes. When the oxygen is gone, the blood is considered "deoxygenated."
Blood goes from the left atrium into the left ventricle, which then pumps the blood through the aotra to the lungs, where it is oxygenated. The blood then circulates back into the heart through the right atrium, which pumps the blood to the right ventricle. The right ventricle then pumps the blood out to the rest of the body.
Blood...

Well dear, don't you know? It circulates throughout your entire body! We need that blood to survive or live! Ok, again, this may not be the right answer, people can improve it. Thank you for using my answer
Heart
veins
The heart is a pump that circulates the blood around the body
circulates blood
It circulates to your brain, but it circulates from your heart.
The pure blood after circulation leaves the heart and enters into the aorta or the aortic arch. Then from here it circulates in the whole body for the exchange of materials. The impure blood, coming from the superior and inferior vena cava, circulates in the heart and enters into the lungs through the pulmonary artery for its purification.
The heart circulates blood to all other organs in your body.
The arteries take blood away from the heart and circulates around the body the capillaries are the vessels that go to the heart.
because it circulates blood
Blood is pumped from the heart to the rest of the body through arteries. It then travels through capillaries, where oxygen and nutrients are exchanged with tissues, before returning to the heart through veins. This process repeats in a continuous loop to supply the body with oxygen and nutrients while also removing waste products.
The heart circulates blood throughout our bodies.
The heart is a muscle and gets its nurisment from blood that flows through it. And it also pumps and circulates blood through it in large vessels and chambers.
