Human Anatomy and Physiology: Free Course

About this course

Human anatomy and physiology connects body structures with their functions. This extensive recorded course surveys organ systems, cellular mechanisms and selected clinical examples used in the source teaching. Study the complete public source playlist from Khan Academy in English, with all 152 recordings in the on-site classroom. Original lesson titles, source order and repeated entries are preserved.

Course Overview

The curriculum includes circulation and blood, respiration, digestion, renal function, nervous signaling, endocrine control, immunity, skin, skeletal muscle and reproduction. Cellular explanations such as membrane transport and muscle contraction connect larger structures with mechanisms. Reproductive recordings include pregnancy physiology and selected complications, so the source extends beyond a purely anatomical atlas. Original titles include NCLEX-RN and MCAT teaching contexts, but watching this playlist does not confer a professional credential or establish current examination coverage. The source order interleaves systems and retains correction videos, including a sodium-potassium-pump correction. Use the material for structured conceptual study and consult the correction together with the original explanation.

How to study the course

• Videos 1–38: this part of the source list includes “Lub Dub” through “Two Circulations in the Body”. Define the terms used in a mechanism. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 39–76: this part of the source list includes “Types of hormones” through “Countercurrent multiplication in the kidney”. Trace a process through the structures involved. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 77–114: this part of the source list includes “Transport of sperm via erection and ejaculation” through “Testosterone”. Compare explanations without merging distinct conditions. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 115–152: this part of the source list includes “Ruffini's Ending and Hair Follicle Receptor” through “Myosin and actin”. Use the recordings to check a study map. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.

Who is this for?

This course suits health-science learners and readers studying the anatomy, physiology or mechanisms named in the course. It also provides a recorded reference for revisiting a topic after an earlier lesson or study attempt. Choose examples appropriate to your background and allow time to work through the method instead of judging understanding only by how familiar the terminology sounds.

Before you start

Foundational biology and relevant body-system terminology are helpful. These recorded explanations support educational study; they do not provide a clinical assessment or professional credential. Diagnostic and treatment discussions belong to the original recorded teaching edition.

Put the lessons into practice

Create a labeled study map for one organ system and trace a process through its main structures. Connect one step with a cellular mechanism, such as transport or signaling, and explain the relationship in your own words. Compare two systems that help regulate the same quantity. Use source corrections when reviewing your map, and keep the exercise focused on learning mechanisms rather than assessing an individual's health.

This optional study activity is provided by WikiFree for independent practice. Keep your working notes and use the relevant classroom recording to check a step, definition or interpretation. It is not an instructor-marked assignment.

Certificate / Assessment

Watching the public videos and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. Use your practice output to review what you can explain and repeat independently. The recorded lessons provide study material; completion tracking records your progress through that material.
