Galactic micro world of life and evolution inside of us is so amazing! On the photo below an electron microscope catches the immune system blooming into action

White blood cell in action

A white blood cell (red) wraps itself around a mycobacterium tuberculosis, the causative agent of most cases of tuberculosis.
Phagocyte, as a white blood cell is known as, comes from the Greek word phagein (to eat),
and that’s what the cell does, rendering the infectious cell benign.

Amazing work of fibrin and platelets to clot a wound

Fibrin is a protein created by the body that works with platelets in the blood to clot a wound.
As they reach the wound site, they attach themselves to fibers, and create a mesh. Working with the platelets,
they make a scab that covers the wound until it heals. Though, with the naked eye you would never guess that the process looks like this.

There are approximately 100 billion nerve cells in an adult brian. Each of those communicate with as many as 1,000 other nerves throughout the human body.

The nerves in action

It’s the most complex system in the human body and to study it, scientists use a substance that makes the nerve fluoresce in a scan.
The researchers then take pictures of the nerves in action.

A cross-section of muscle tissue

A cross-section of muscle tissue, surrounded by the extracellular tissue that acts as the connective tissue.

Each muscle fiber is joined together by the connective tissue to make up the complete muscle.
Myasenthia is an neuromuscular disease caused by a faulty relationship between the two.

That’s not coral – but a true-to life model of the human vascular system.

This series of veins have been plastinated using a method developed by Dr.Gunther von Hagens, the scientist behind the often controversial Body Worlds exhibits. A liquid plastic gets injected into the blood stream. When it hardens, scientists can study the system as it is in the human body.
