Why do you not have a pulse in your veins and capillaries (only in your arteries)?

You do not have a pulse in your veins and capillaries because the pulse is generated by the pressure wave created when the heart contracts and pumps blood into the arteries. Arteries are designed to withstand and transmit this high-pressure blood flow, resulting in a palpable pulse. In contrast, veins carry blood back to the heart at lower pressure, and capillaries are small vessels where the exchange of oxygen and nutrients occurs, lacking the ability to transmit a pulse.
