Back from the Brink, the Science of Survival: Peak Performance
Dr Montgomery examines the theme of respiration. Just like racing car engines, humans use oxygen to burn fuels and release the energy that powers each function in every cell. So how do we get the oxygen from the air to the cell, and what happens when oxygen levels in the air are dramatically reduced? Dr Montgomery looks at the airways that carry the oxygen, and the rib-and-muscle bellows which drive air through them. He examines the lung and explains how it passes the oxygen on to the blood cells which grab and hold that oxygen. Then, viewers are shown how the heart pumps these cells around the body through a complex system of blood vessels, where the oxygen is passed onto the cells for another phase of processing. In the second half of the lecture, Dr Montgomery meets some mountaineers who have climbed Everest where there is three-times less oxygen than at sea level. What happens to these people’s bodies when they struggle to stand at the very top of the world?

Gordon Ramsay's Secret Service

Restaurateurs who are looking for a quick fix or social media glow-up are in for the surprise of their lives when famed culinary titan Gordon Ramsay trades his signature chef knives for a state-of-the-art surveillance vehicle and cutting-edge spyware in FOX's all-new unscripted series, Gordon Ramsay's Secret Service. In a Gordon Ramsay series first, Chef Ramsay will venture into struggling restaurants under the cover of night. With the help of a secret source on the inside, he'll gather raw, unfiltered evidence and get a 360-degree view of the major issues facing each restaurant. This insider will not only remain a secret to the staff, but will also help Ramsay infiltrate the restaurant after-hours for a dramatic nighttime black light kitchen investigation that reveals more filth and grossness than ever before. By the time Ramsay reveals his identity, it will be too late for staff to cover up their culinary crimes. Gordon Ramsay's Secret Service will be his toughest assignment yet as he takes drastic measures to transform not only the restaurant but also the staff, because Gordon knows he can upgrade the menu and renovate the restaurant, but the most important change has to come from the people. Are the restaurant and staff willing to accept Gordon's mission, or are they too far gone to be saved?
