Cardiovascular Physiology: Free Course

About this course

Connect the heart’s anatomy, electrical activity and pumping function in this free Ninja Nerd course. The complete sixteen-video cardiovascular-physiology playlist is preserved, including updated and earlier ECG explanations, both cardiac-cycle presentations, blood-vessel topics and blood-pressure regulation. The focus is understanding the recorded physiological mechanisms.

• Microcirculation
• System integration

Course Overview

The course begins with the heart model and its structures before turning to intrinsic and extrinsic conduction. Several ECG presentations provide complementary explanations, including the updated lecture. Cardiac-cycle and cardiac-output recordings then connect electrical activity with pumping function. The vessel, capillary and microcirculation lessons expand the view beyond the heart, and the final blood-pressure recordings address fundamentals and regulation. All sixteen source lectures remain available; the older and updated versions are retained together as teaching references. This is the recorded physiology sequence, not a full clinical-cardiology program. Its practical study value is to make electrical, mechanical and vascular concepts part of one understandable model.

How to study the course

• Start with anatomy and conduction, making a small structure-and-function map. Distinguish the physical structure from the signal moving through it.
• Study the ECG and cardiac-cycle recordings, then cardiac output. Compare the purpose of each explanation instead of assuming similar titles make a lecture unnecessary.
• Complete vessels, microcirculation and blood-pressure regulation. Explain how the later topics depend on the earlier heart and pumping concepts.

Use the searchable classroom lesson list to revisit a specific explanation. Pause after a useful demonstration, reproduce a small example and explain the result in your own words. Keep a short note of what worked, what changed and what you still need to understand before moving on.

Who is this for?

This course suits medical, nursing, allied-health and biology students studying normal cardiovascular function. It also supports revision before a separate course in disease mechanisms or clinical interpretation.

Before you start

Basic anatomy, physiology and scientific graph-reading skills are helpful. Use formal study references alongside the recordings. Video study does not provide an individual ECG assessment, supervised clinical competence, treatment advice or a professional qualification.

Put the lessons into practice

Create a concept map linking heart structure, conduction, the cardiac cycle, output and circulation. Use one short explanation for each connection and identify the source lecture that supports it. Compare the two cardiac-cycle presentations or the ECG versions and note which visual explanation helps you most. Add a separate section for blood-pressure regulation without turning the exercise into a personal-health assessment. Finish by explaining the overall system aloud and checking whether each link has a physiological purpose rather than merely repeating a label.

This optional activity is provided by WikiFree for independent practice. It is not a graded assignment from the instructor. Keep your working notes, check the result against the task you defined and return to the relevant lesson when an assumption or technique is unclear.

Certificate / Assessment

Watching the public videos and using WikiFree progress tracking does not award a certificate, exam voucher, academic credit or instructor assessment.

Use your practice output to review what you can now explain and repeat independently. Completion tracking records your study progress; it does not replace an assessed qualification or professional experience.
