Electricity is the manifestation of traveling currents. These currents however are unable to move unless one were to complete a "circuit" (Word you are looking for). If the circuit is not completed electricity doesn't travel.
Ikr people been putting links and I don’t like it either
In human anatomy, it is the heart that pumps the blood so that it is distributed to throughout the body to provide oxygen and nutrients to the other organs. Hence, it passes different conduits. The largest conduits are the arteries which carries blood away from the heart. Pulmonary arteries, in particular, direct the blood from the heart's right ventricle towards the lungs. The smaller diameter conduits are the veins. Generally, the veins carry deoxygenated or used blood and bring it back to the heart. Exceptions to this is the pulmonary vein and umbilical vein. Finally, the capillaries are very small blood vessels that transport blood between the arteries and the veins.
From the choices, the false statement is letter B. Although this could be true for the pulmonary and umbilical vein, the majority of the veins still transport the blood back to the heart.
I’m not sure but I think it’s B
