Human biology

This course is a part of AP®︎ Biology, a 38-course Topic series from Khan Academy.

Your body is an amazing system! The human body is made up of groups of organs, called organ systems, that work together to keep the body in balance. In this section, we'll travel from the circulatory system, to the nervous system, to the immune system and beyond. Learn about the amazing biology that keeps your body ticking!

This course contains 5 segments:

Circulatory and pulmonary systems

As humans, we really like breathing oxygen. That's because the cells in our body will die if they don't get the oxygen they need to function. This tutorial describes how gases are exchanged between blood and the atmosphere in our lungs, and how oxygen is then pumped through the body by way of blood and the circulatory system.

The neuron and nervous system

Neurons are specialized cells that allow our bodies to transmit signals from one part to another quickly. In this tutorial, we'll explore the anatomy of a neuron and the mechanism by which neurons transmit signals.

The kidney and nephron

How do we get unwanted substances out of our blood? Through the kidney. This tutorial goes into detail about how the kidney works.

Muscles

Without muscles, we wouldn't be able to do much of anything. This tutorial explores what muscle cells are and how they contract to let us move our bodies.

Immunology

How does you body defend itself against invaders, such as disease-causing bacteria and viruses? Learn more about your immune system, what cells make it up, and how it works in many different ways to protect you from harmful microbes (pathogens).
