Understanding Blood Pressure

The video tutorial explains blood pressure as the force exerted by blood on the walls of blood vessels. It introduces the sphygmomanometer as the instrument used for measuring blood pressure. The tutorial differentiates between systolic pressure, occurring during ventricular contraction, and diastolic pressure, occurring during ventricular relaxation. Normal blood pressure values are given as 120/80 mmHg. High blood pressure, or hypertension, is also discussed. The video concludes with review questions to reinforce learning.
