Course Overview
The opening anatomy and mechanics lectures establish a foundation for understanding movement of air. Resistance, surface tension and compliance then explain different parts of the work involved in breathing. The sequence continues through lung volumes, ventilation-perfusion relationships, the respiratory membrane, gas properties and internal respiration. Hypoxia and the oxygen-hemoglobin discussion provide context for transport, while the three regulation lectures address respiratory centers, chemoreceptors and factors influencing breathing. Exercise, high altitude and forced spirometry complete the recorded set. All twenty lectures are preserved, including every numbered part. This is the published physiology teaching edition; it does not include supervised pulmonary testing, laboratory assessment or a professional qualification.
How to study the course
- Study anatomy and Mechanics Parts 1–3 together. Sketch the relationships being described and keep pressure changes connected with the movement of air.
- Work through resistance, compliance, lung volumes and gas-exchange topics. Compare the purpose of each concept before combining them into a larger explanation.
- Complete the control, exercise, altitude and testing lectures. Use the earlier mechanism notes to explain why a new situation changes the physiological discussion.
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?
The course suits medical, nursing, allied-health and biology students studying respiratory function. It also helps returning learners review a system before studying related disease mechanisms in a separate course.
Before you start
Basic anatomy, introductory physiology and comfort with scientific terms are recommended. Allow extra time for longer lectures and diagram practice. Video study does not provide clinical-testing competence, diagnosis, treatment guidance for an individual or assessed professional training.
Put the lessons into practice
Create a concept map connecting ventilation, lung mechanics, gas exchange and oxygen transport. For each link, write a short explanation based on a specific lecture and identify the variable or relationship being discussed. Add a separate branch for control of breathing, then compare the course’s exercise and altitude examples in educational terms. Keep normal physiological reasoning distinct from any clinical interpretation. Finish by explaining one mechanism aloud without reading your notes, then return to the recording to check whether the explanation preserves the important relationships.
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.
