KINE 1P90 Lecture Notes - Lecture 10: Atherosclerosis, Pheochromocytoma, Orthostatic Hypotension
More blood is delivered to the tissues during ventricular systole than during ventricular diastole. When the heart is not ejecting blood into the arterial system, the pressure in the arteries falls to zero as blood drains off into the rest of the vasculature. Velocity of blood flow is the slowest in the veins because the blood must move uphill against gravity in these vessels. The force exerted by the blood against the inside of the blood vessels. The main driving propelling blood to the tissues. Although such a force occurs throughout the vascular system, the term blood pressure refers to arterial pressure in branches of the aorta. Blood pressure rises and falls in a pattern corresponding to the phases of the cardiac cycle. Systolic pressure- the maximum pressure achieved during ventricular contraction (ventricular systole) Diastole pressure- the lowest pressure achieved during ventricular relaxation (ventricular diastole) Pulse pressure- the difference between systolic and diastolic pressures.
