Anatomy & Physiology Online Classes

Explore 21 curated anatomy & physiology online classes for homeschoolers and educators. Each resource has been reviewed for quality before being listed.

Learn how the human body is built and how its systems work together to keep our bodies moving. Anatomy usually starts with "gross anatomy" or "macroscopic anatomy," the study of the major parts of the body, and progresses to microscopic anatomy including cytology, the study of cells, and regional anatomy, the study of specific regions of the body. Systemic anatomy then looks at the systems that work together to perform specific functions such as breathing, digestion, or the pumping of blood. Find resources here for any part of anatomy you're interested in, whether you're learning the basics or just trying to reinforce your learning.

Immune system physiology

Chances are, you’ve had a fever or a cough at least once in your life (unless you live in a bubble, in which case you should probably go out more!) Have you ever wondered why your body reacts this way? Your body has a deadly arsenal of weapons agains...

Integumentary system physiology

3B: There is really more than meets the eye with skin. Yes, it does make us look nicer than a bag of bones, muscles, and organs. But it also serves other important purposes which range from guarding the body against infection to sensation to allowing...

Nervous system physiology

3A: Neurons transmit information to one another through electrochemical signals. They make up the motor nerves that allow you to type an essay, the sensory nerves that let you feel a fluffy dog, and your brain, allowing to remember the content of thi...

Reproductive system physiology

Our genes are survivors. Even though a person might die, his or her genes will go on to the next generation and then the next generation… Some genes are exactly the same as the ones in your great-great-great-grandmother! Yet, with the exception of id...

Renal system physiology

3B: If you want to learn more about the renal system, then urine the right place! (Pun aside, the kidneys are about more than just making urine). Every thirty minutes, your kidneys filter the entire blood supply in your body. Imagine a dirty pool fil...

Lymphatic system physiology

Your heart pumps roughly 20 L of blood throughout the day to your tissues. The plasma component of blood (not containing blood cells) leaks out through capillaries (the tiniest of blood vessels) and is mostly reabsorbed. However, about 3L of the plas...

Muscular-skeletal system physiology

How do our muscles work? When we decide to kick a ball or shake a leg, how do we get our bodies to do that? Which muscles do we control? Which muscles control us? Learn how our muscles work at the smallest, most cellular level. Then see how nature sc...

Gastrointestinal system physiology

Do you live to eat, or eat to live? Folks fall on both sides of this question, but who can deny the powerful role that food and water play in our everyday lives. If we were cars, food and water would be the gasoline. Eating keeps us moving, laughing,...

Respiratory system physiology

Place your hand on your ribs and inhale deeply. You’ll notice that your chest expands and your back straightens. As this occurs, air is rushing through your windpipe and branches off to either your left or right lung. After 20 to 30 more branch point...

Physiology and Health

Physiology and Health approaches health education from the perspective of wellness. This means that it aims to provide the basis for wise decisions and choices that promote total physical, mental and social well-being The first half of the course foc...

Circulatory system physiology

Your heart sits in the middle of your chest and pumps blood from about 4 weeks after conception until the day that you die. It never stops, and over your lifetime it will pump ~175 million liters of blood. To visualize that, imagine the amount of wat...

Vital Signs: Understanding What the Body Is Telling Us

The vital signs – heart rate, blood pressure, body temperature, respiration rate, and pain – communicate important information about the physiological status of the human body. In this six-part course we explore the anatomy and physiology underlying...

Introductory Human Physiology

In this course, students learn to recognize and to apply the basic concepts that govern integrated body function (as an intact organism) in the body's nine organ systems....

Anatomy and Physiology Online Course

Duration: 19 hours, 1 minutes Number of Lessons: 27 This Anatomy & Physiology course is perfect for both high school and college students, and is more in-depth than standard introductory courses. Professor Cardella brings his years of experience...

Organ systems

3A: The very fact that you are able to understand this sentence means that neurons in your brain (85 billion in total) are talking to each other. Neurons are the living substance of the nervous system, which extends beyond the brain to the spinal cor...

Anatomy & Physiology Crash Course

In this episode of Crash Course, Hank introduces you to the complex history and terminology of Anatomy & Physiology....

Endocrine system physiology

When you’re nervous before an important speech, or asking someone out on a date, you might feel butterflies in your stomach. This is actually the result of your endocrine system releasing hormones! You can’t really point to any single organ as “the e...

Health and medicine

No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all d...

Anatomy of the Abdomen and Pelvis; a journey from basis to clinic.

In this anatomy course you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will help you to find new insights and understanding of this part of the...

Anatomy & Physiology

You probably have a general understanding of how your body works. But do you fully comprehend how all of the intricate functions and systems of the human body work together to keep you healthy? This course will provide that insight. By approaching th...

Anatomy and Physiology (online)
