It takes about 1 minute for the heart to circulate blood through the entire body.
heart contractions
The blood vessels of an embryo are connected to both the heart (internally) and the umbilical cord (externally). The heart beats and helps circulate the blood to some degree but mostly it is the heart of the mother that helps circulate the blood to and from the embryo.
no, the heart is just a pump to circulate blood. it performs no other operation
It takes about 20-30 seconds for blood to circulate through the body before returning to the heart.
Blood flows from the right atrium of the heart into the right ventricle to the pulmonary artery to the lungs where the blood is oxygenated. From there it flows to the pulmonary vein to the left atrium and ventricle, then to the aorta.

It is a continuous process.
