Part of the "Gunther's ER" series. The human brain suffers irreversible damage if deprived of oxygen for even a few minutes-a fact Dr. Gunther von Hagens demonstrates by utilizing human cadavers as examples. Simulating an artery injury to illustrate oxygen depletion through blood loss, von Hagens then focuses on problems affecting the trachea, the top priority for ER doctors. In order to show the major structures of the airway and how they can be blocked by foreign objects, von Hagens inserts an endoscope into his own throat and saws a frozen body's throat in half, revealing the major structures of the airway and their potential weaknesses. Red Cross first-aid expert Emma Rand explains simple techniques for clearing the airway, while emergency medicine consultant Dr. John Heyworth shows how paramedics treat complex trachea damage.

Explores how eyes work and how eyes help us understand the world. Explains how safe behaviors and healthy habits can prevent illness and injury to eyes. Discusses what to expect from an eye examination and other eye tests. Talks about how visually impaired children walk with a white cane and read Braille.
The body is like a self-supporting hospital, able to deal with its own with wounds, bacterial invasions, fractures, and obstructions to its various passages. Follows the sequence of events over seconds and weeks when skin or bone is damaged, and shows the defensive reactions of blood clotting, fever, and mending of bone fractures.
When the nerve cells of squid suffer an injury, something unexpected happens with the tiny pouches of colored pigment, called chromatophores. A MIT scientist discusses this phenomenon, and how it can be used and modeled on the computer with some surprisingly simple rules. Part of the "Science Out Loud" series.
Part of the "Gunther's ER" series. Beyond the immediate risks to a patient's life, doctors must also identify other bodily damage. Dr. Gunther von Hagens examines the kinds of injuries that can lead to permanent disability if not quickly addressed. Dissecting a female body donor who died after falling from a window, von Hagens locates fractures throughout her skeleton, explains how bones break, and bends a human spine to discover how much force it can withstand before snapping. Also investigates the causes and consequences of brain damage. Recreating head injury to the exposed brain of another cadaver, von Hagens illustrates how the rigid, closely fitting skull can actually damage the brain it is meant to protect.

Part of the "Gunther's ER" series. As Dr. Gunther von Hagens makes clear, a shortage of blood can mean that insufficient oxygen is reaching the major organs, usually resulting in shock and organ failure. Opens with a graphic bleeding demonstration, re-creating injury to blood vessels in the hand of a cadaver. Also examines the consequences of blood loss in the body's vital organs by creating knife wounds in the torso of a frozen body, then sawing it into slices to reveal the path of the blades and the shocking extent of the damage. Also explores a lesser well-known cause of blood loss-fractured bones-which von Hagens illustrates in an experiment in which a femur dissected from a fresh cadaver is made to bleed as it would in life.
