Lignes de vie

In a refined style, one line then two then three undulate and draw abstract shapes evocative of life, electrocardiography, heart, DNA, umbilical cord. The opportunity to explain to children that the umbilical cord is the organ that joins the fetus to its placenta in the mother's womb. Blood vessels (two arteries and a vein) supply nutrients and oxygen to the embryo and then the fetus during pregnancy. The film begins like an electrocardiogram, which is also an opportunity to explain the heart's electrical activity. The heart muscle pumps blood out of the heart with each beat and this activity can be measured and recorded by an electrocardiogram. The heart, like all muscles, contracts under the influence of electrical impulses, and the electrocardiogram records each electrical impulse. To do this, the electrocardiogram is connected to electrodes placed on the ankles, wrists and chest.
