Human beings are arguably the most complex organisms on this planet. Imagine billions of microscopic parts, each with its own identity, working together in an organized manner for the benefit of the total being.

It's an essential component of the circulatory system, and without it, the system couldn't supply oxygen and nutrients around the body.

Atherosclerosis is not only a tongue twister; it’s the leading cause of heart attacks worldwide. Understanding how this disease can lead to an attack starts with how your immune system works for and against you.

Your body’s digestive system is responsible for the ingestion, digestion, and absorption of your food and nutrients. Made up of your salivary glands, esophagus, stomach, gastrointestinal tract, pancreas, and a suite of special enzymes, this system absorbs and processes everything you need, discarding the stuff you don’t.
The digestive system does more than break down food — here's how it fights pathogens and why it’s so important for survival.

If you think puberty is all hormones are good for, think again! Hormones are incredibly important in many of our body’s biological processes.

Testosterone is often considered the muscle building hormone, and for good reason. Deep dive into how this hormone influences muscle growth and what you can do about it.
Your immune system protects your body from foreign substances––like the bacteria, viruses and parasites we encounter all the time––by producing an “immune response.” But how exactly does this complex orchestra of cells work to protect your body… and what happens when it’s out of tune?
A new immune discovery could provide universal cancer treatment — here's how it works.

As the largest organ of the body, this system includes the glands, nerves, fat and muscles under the skin that you don’t see. Working together, this system helps keep our bodies at a livable temperature, protects our squishier internals from harm, and helps us interact with the world via touch.

Scientists may have found a way to reprogram skin cells into any cell the body needs. Here's how it works.
This system plays an essential role in keeping you healthy and seems like it only comes out to play when you’re sick, but there’s so much more to it.
Scientists recently discovered a never-before-seen drainage system in the brain! Here's how it could lead to exciting breakthroughs in the treatment of neurological diseases.
Whether you want to walk, run, dance, swim, or sit for hours watching science videos, your musculoskeletal system allows you to move through the world with precision and control. Within this system, some 200+ bones and 600+ muscles support your body’s weight and maintain its position.

Your skeleton has the difficult task of being strong and hard enough to hold your whole body up, but bendy and shock-absorbing enough not to shatter upon minor impact. So when something goes wrong in the bone-forming process, your bones can get weaker - and the results can be shattering.

Our bodies rely on an ultrafast nervous system to send impulses very quickly. Without this command center sending communications throughout the body, our movements, thoughts, and responses to the world around us would not be the same.
If we could fully map the inner workings of our brain, we could understand disease, consciousness, and what it is that makes us human. Only snag? There are more connections in the human brain than there are stars in the Milky Way. So, how close are we to mapping the human brain?
Sex might be the first thing that comes to mind when thinking about reproduction. Yes, offspring are the result, but this system consists of organs and glands that do a lot more than that.

Advances in stem cell research could change what it means to reproduce. Are we ready for the next revolution in baby-making science?

You breathe all the time, whether you think about it or not. But how does that even work? And what is breathing for?
This breathing air sac model serves as a proof of concept for a field where printing vasculature has been one of the biggest challenges.
