Blood Pressure Regulation (Lecture)
How is Blood pressure regulated? How do cardiac output and peripheral resistance fit into the equation? What are the negative effects of hypertension (high blood pressure). I explore these concepts and more in this video

The Cardiac Cycle
We all know that the heart beats. We don't even need to think about it - it just happens. But, there are many details that need to come together in order for it to happen efficiently and effectively. In this videos, Leslie goes through...

Cardiac Output
This episode goes through the details involved in determining cardiac output. It goes into the cardiac output formula, showing how stroke volume and heart rate are involved in determining cardiac output. It also deals with what happens...

Net Hydrostatic Pressure and Filtration Pressure
In this episode, Leslie explains what Net Hydrostatic pressure is and how to calculate it. He also shows how filtration pressure is determined by Net Hydrostatic Pressure and Osmotic pressure. Lastly, he shows how High Blood Pressure can...

How Blood Flows Through the Heart
In this video, I go through the process of how blood flows through the heart. It shows blood entering via the vena cave to the Right atrium, then getting pumped into the right ventricle, to the pulmonary vein to the lungs, to the left...

What Stroke Volume is and How to Calculate it
In this video, I talk about what stroke Volume is - the difference between end-diastolic volume and end-systolic volume. SV = EDV-ESV. Enjoy!

What Is Hypertension?
In this video, we cover hypertension. We're going to deal with things like Cardiac Output, peripheral resistance, stroke volume and heart rate, and talk about how those values are related to blood pressure. We also deal with the symptoms...

Drugs That Affect the Cardiovascular System
The circulatory system, like every other system in the body, is very important. And when there are problems with your cardiovascular system, your doctor may prescribe various medications to help. Let's take a look at five kinds of...

Peripheral Resistance and Blood Flow
This is an answer to a question that was asked when I did my Anatomy & Physiology Academy on how exactly resistance works when it comes to blood flow. In this video, I explain peripheral resistance in a bit more detail and how there are...

Regulating Peripheral Resistance - Part 1
Mean Arterial Pressure is Cardiac Output times Peripheral Resistance. That means if there's a change in Peripheral Resistance, that will result in a change in Mean Arterial Pressure. In this video, Leslie gets into the topic of...

An Introduction To Cardiovascular Disorders (Lecture)
In this video, I start talking about what happens when things go wrong with the cardiovascular system. We start with a general review of the cardiovascular system, starting with the absorption of nutrients into the blood all the way to...
