Systolic blood pressure
The blood pressure is the pressure in the arteries created by the large quantity of blood circulating in them. The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
The upper Blood Pressure Number is the Systolic, Which is the force of blood in your arteries when you heart beats.
true
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.
