3. In medicine, a person's pulse is a pressure wave caused by the expansion of the arteries as a result of the circulation of blood pumped by the heart.
4. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells.
Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.
