Regenerative phase of an inflammation

In the regenerative phase, inflammation-resolving messenger substances are released. Macrophages of type M2 dispose of cell and tissue debris. At the same time, other immune cells begin the first repair measures. Author: 3sat/nano/DOCUVISTA Filmproduktion/Marilena Schulte,Maike Wurtscheid/Jörg Beck

Anatomy and function of the penis

The male penis consists of the root, shaft and glans. When a man is sexually aroused, his brain sends signals to the nerves in the erectile tissue in the shaft. The penis becomes stiff and erects. Translation and dubbing: alugha Click here to see more videos: https://alugha.com/TerraX Thumbnail

Excessive immune response

In the so-called cytokine storm, larger and larger amounts of cytokines are released uncontrollably. They then also "mark" healthy cells and cause the immune cells to attack the body's own tissue.
