Blood Vessels, part 2: Crash Course A&P
And now we return to blood vessels. In this episode, we start discussing what blood pressure is, how it can become "high", and what that means for our health. One of the more interesting points is that your body has ways of dealing with...

How the Heart Changes with Exercise
In this video, Jonathan from the Institute of Human Anatomy discusses the anatomy of the heart and the changes that occur during exercise as well as long term adaptations of the heart and cardiovascular system.

Autonomic innervation of the heart
This video tutorial briefly covers the sympathetic and parasympathetic role on heart innervation. It focuses on the following: - Sympathetic neurotransmitters (epinephrine and nor-epinephrine) and receptors (adrenergic). -...

Hypertrophic Cardiomyopathy How the Heart Enlarges Pathologically
In this video, we discuss hypertrophic cardiomyopathy, the mechanism by which a heart enlarges in response to chronically elevated afterload and high blood pressure.

More Pressure-Volume (PV) Curves
In this video, we discuss another type of pressure-volume loop in detail that you may encounter in your anatomy and physiology class.

Mechanisms of β1-blockers, Calcium-channel Blockers, & α-blockers
In this video, we will be exploring the mechanisms of action of several antihypertensive drugs that act in the cardiovascular system and on the heart: β-blockers, calcium-channel blocker's, and α-blockers.

What is the Frank-Starling Mechanism in Cardiophysiology?
What is the Frank-Starling Mechanism? We will discuss this by talking about the effects of preload, left ventricular stretch and elastic recoil, and changes in stroke volume.

Understanding the Amazing Adaptations of the Heart During Exercise
In this video, Jonathan from the Institute of Human Anatomy discusses a type of high intensity exercise, how to do it, and how often you should incorporate it into your workout routine. He also discusses the relevant anatomy and the...

Understanding the Increased Urination During Pregnancy
In this video, the teacher dissects a kidney and explains how it produces urine, then delves into why pregnant women have to pee more frequently. He discusses the changes in the cardiovascular system and kidneys during pregnancy, and how...

Hypertension Treatment and the Physiology Behind it
What are the mechanisms that underlie the drugs that are used to treat hypertension? Drugs like ACE inhibitors, diuretics, and beta-blockers? That's what we cover in this video.
Curated Video
Blood Pressure and Mean Arterial Pressure
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.

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

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...
Curated Video
Pressure Reflexes and Mean Arterial Pressure
What happens when Mean Arterial Pressure goes to high? Baroreceptors fire, signal goes to the medulla, parasympathetic activity goes up, Sympathetic Activity goes down, which ends up resulting in an increase in Mean Arterial Pressure....

The Pathophysiology of Hypertension
What are the mechanisms that underly the development of hypertension? How is the sympathetic nervous system involved? What does the Renin-angiotensin system have to do with anything. Watch and Learn.

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...

Cardiac & Vascular Function Curves EXPLAINED
In this video, I will be explaining the rationale behind cardiac and vascular function curves and various points on them.

Basics of Cardiac Output for Cardiophysiology
In this video, I discuss the basics of cardiac output (CO or Q) for anatomy & physiology.

Calculating Several Cardiovascular Parameters
In this video, I do a set of problems (given some data) in which we calculate Pulse Pressure, Mean Arterial Pressure, Stroke Volume, Ejection Fraction, Cardiac Output, and Total Peripheral Resistance.
