In this episode, Leslie first defines what blood pressure is and shows how it varies in the blood vessels throughout the body. He then shows what Mean Arterial Pressure is and goes into two different ways to calculate it.

00:00 Intro
00:36 Heart Function
01:05 Heart Pumping blood inside the human body
01:43 What is Blood Pressure?
03:26 Blood pathway as it leaves the heart
03:50 Blood pressure is greater nearer the heart.
04:17 Chart- Blood pressure values as it leaves and goes back to the heart.
07:16 Heart ventricular contraction (Systolic Pressure)
08:44 Blood pressure values on the way back to the heart
09:21 Normal blood pressure values
10:25 What is Mean Arterial Pressure (MAP)?
11:28 Calculating Mean Arterial Pressure #1
➯ MAP = CO x PR
12:40 What is Peripheral Resistance?
13:03 Calculating Mean Arterial Pressure #2
➯ MAP = Diastolic BP + 1/3 (Systolic BP - Diastolic BP)
