Explanation:
Detailed explanation-1: -The force that blood exerts force against the wall of a vessel is called blood pressure. 2. The pressure of blood inside the artery during contraction is called systolic pressure and pressure in an artery during relaxation is called diastolic pressure.
Detailed explanation-2: -The venous side of the circulation is a low-pressure system compared with the arterial side. Pressure within the named veins is usually between 8 and 10 mmHg, and CVP is 0–6 mmHg (3, 9).
Detailed explanation-3: -The systolic pressure indicates the arterial pressure resulting from the ejection of blood during ventricular contraction, whereas the diastolic pressure represents the arterial pressure of blood during ventricular relaxation.
