Summary: This edition of Science Screen Report explores the synergy of two different physiological systems: the respiratory system, for acquiring and processing oxygen, and the circulatory system, for the internal transportation of oxygen and nutrients. Emphasizing the vital roles of the heart, the lungs, capillary action, and Earth's oxygen-rich atmosphere, Energy for Life illustrates clear connections...

Summary: Following an opening segment on the importance of oxygen to the human body, this program studies the structure and function of the respiratory system. Topics include the anatomy of the upper respiratory tract, the lower respiratory tract, and the alveoli; the diffusion of gas molecules through the walls of the alveoli and capillaries, and the effect of high altitude on the diffusion process;...

Summary: The human brain suffers irreversible damage if deprived of oxygen for even a few minutes-a fact Dr. Gunther von Hagens demonstrates in this program, utilizing human cadavers. 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. Von Hagens inserts an endoscope into his own throat...

Summary: Using the analogy of an automobile's system of fuel intake and exhaust, this program explores the makeup and functions of the respiratory system. Topics include the processes of respiration; the organs involved in respiration; why cells need oxygen; structure and functions of the lungs; relationship between the brain and the respiratory system; and a detailed look at what's behind the "simple"...

Summary: Lung disease-or pulmonary fibrosis, to use a more clinical term-is actually a set of illnesses that cause progressive scarring inside the lungs. This program takes a close look at the disease, the ways in which it is often detected, and current strategies for treating it. Showing how, over time, pulmonary fibrosis replaces healthy lung tissue with scar tissue, the program demonstrates how this...

Summary: This program takes a close look at the organs of the human circulatory system and how they work to sustain life. After an introductory overview, the composition of blood-its plasma, erythrocytes, leukocytes, and platelets-is analyzed, blood types and Rh factor are considered, the role of hemoglobin in transporting oxygen is explained, and the anatomy and function of the heart is examined....

Summary: This program examines how oxygen and carbon dioxide are transported throughout the body, guided by the brain as it reacts to internal and external stimuli. The process of breathing is modeled by a swimmer, the control of breathing by the brain is analyzed, and oxygen intake by the lungs and transport by red blood cells are discussed. The complementary actions of the circulatory and respiratory...

Summary: This program follows the journey of a red blood cell around the circulatory system to demonstrate the efficient and elegant design of oxygen and food delivery to all parts of the body and the removal of wastes before they can do harm. It shows how the veins and arteries are structured to perform their tasks: muscular arteries to transmit the force of the heartbeat, veins with valves to insure...

Summary: This program explains why the body needs regular supplies of air and how it gets them. The camera follows the process of breathing through the ultra-thin membrane of the lung into the blood, showing how the varying demand for oxygen is met by the exchange of information between the brain and the chest muscles and how the body rids itself of carbon dioxide.

Summary: As we reach and move beyond our 40s, imperfections in our physiology-many that we have unknowingly carried for years-begin to reveal themselves. This episode explores the human body's ability to draw on its own reserves when things go wrong. During a routine checkup, 53-year-old Alan is found to have a life-threatening thoracic aneurysm in the blood vessel supplying his vital organs. Viewers...

Summary: In this program, world-renowned anatomist Gunther von Hagens takes viewers into the inner workings of the respiratory and circulatory systems-exposing the path that oxygen takes through the human body. Von Hagens dissects lung tissue to reveal alveoli, delves into the atria and ventricles of the heart, and examines the intricate network of blood vessels that spreads through the abdomen, limbs,...

Summary: Blood is a fluid with amazing properties. In this program, we learn that blood acts virtually like an organ and fulfills a host of complex tasks within the organism, from oxygen transport to defending against infection. The crucial importance of blood in maintaining physical equilibrium has led to the development of numerous technologies dealing with its classification, preservation, and...

Summary: As Dr. Gunther von Hagens makes clear in this program, a shortage of blood can mean insufficient oxygen reaches the major organs-usually resulting in shock and organ failure. The program opens with a graphic bleeding demonstration, re-creating injury to blood vessels in the hand of a cadaver. Von Hagens then examines the consequences of blood loss in the body's vital organs by creating...
