The heart is a pump that circulates the blood around the body
William Harvey, an English physician, demonstrated how the blood circulates in 1628 with his publication "De Motu Cordis" (On the Motion of the Heart). Harvey showed that the heart acts as a pump to circulate blood through the body in a closed system of arteries and veins. His work revolutionized the understanding of the cardiovascular system.
The heart is the organ that acts like a pump, pumping blood throughout the body to deliver oxygen and nutrients to cells and remove waste products.
The Heat is the pump that circulates blood through the body.
The heart is a large muscle which acts like a pump and pushes the blood around the body
The heart acts as a pump which circulates oxygenated blood through the arteries around the body at high pressure. Once gaseous exchange takes place between the cells and capillaries the deoxygenated blood flows back to the heart through the veins where it is pumped to the lungs via the pulmonary arteries. When the blood becomes oxygenated by external respiration it flows back to the heart via the pulmonary veins and the cycle starts again. Therefore the heart acts a pump and the blood vessels are a channel to circulate the blood around the body.

In frogs, the heart acts like a pump, circulating blood throughout the body. It consists of three chambers: two atria and one ventricle, which work together to propel oxygenated and deoxygenated blood. The contraction of the heart muscles creates pressure that drives blood into the lungs and the rest of the body. This efficient system supports the frog's metabolic needs, especially during activities like jumping and swimming.
