Introduction to Human Anatomy Lecture 39 Notes: CV System

Overview

After today, one more section to go.  This lecture costs 49 minutes of your time:

Details

Systole is when ventricles contract.  Contraction phase and ejection phase.

Diastole, when ventricles relax.  Relaxation and filling phase.

A normal cardiac cycle of 75 beats per minute lasts 0.8 seconds/beat.

Arteriolar depolarization from the P wave.  Ventricular depolarization from QRS wave.  T wave ventricular repolarization.

The right ventricle works 6x harder and generates 6x the pressure compared to the left ventricle.

Bicuspet valve is the mitrial valve.

He goes through a long demonstration with the room as the heart.  Add two doors.

If blood flow to the brain stops for 4 minutes, you’ll go brain-dead.
