Xand van Tulleken, Raksha Dave and John Sergeant discover the parallels of the Great Plague of 1665 with the Covid-19 pandemic. Ch1. Outbreak The epidemic is traced back to its source in the parish of St Giles in the Fields, now at the heart of London's theatre district. The program also examines the symptoms of the disease and uncovers new research into the plague bacteria that could overthrow accepted ideas about how the infection was spread. Ch2. Decimation Xand heads to St Barts hospital to look back at historical records which show that nursing staff stayed behind and risked their lives to help the sick. Elsewhere, John investigates why infection rates were so different between the rich and poor, examining clothes typical for each group in the 17th century. Ch3. Aftermath Xand visits Samuel Pepys' parish church and discovers the sad tale of the Poole family, who within 11 days lost all five of their children. He also heads to Eyam in Derbyshire, revealing the heroic story of self-sacrifice that saw all 700 villagers lock themselves in to try to stop the disease from spreading to surrounding areas. Raksha Dave trials 17th-century disinfection methods and reveal a surprising substitute that can be just as effective as modern antibacterial cleaners.

The human immune system is the most complex biological system we know, after the human brain, and yet, most of us never learn how it works. Or what it is. Your immune System consists of hundreds of tiny and two large organs, it has its own transport network spread throughout your body. Every day it makes hundreds of billions of fresh cells. It is not some sort of abstract entity. Your immune system is YOU. Your biology protecting you from the billions of microorganisms that want to consume you and from your own perverted cells that turn into cancer. It's so manifold that it is impossible to cover in one video, so we’ll make a series looking at different aspects of it. Today, what happens when your body is invaded and your first lines of defenses are engaged in a fight for life and death?

The story of a human life, from first cry to final breath, told from within the body. This documentary film combines state-of-the-art special effects, pioneering CGI, startling realistic models and real in-body photography. Exploring human physiology from birth, through the drama of puberty, into adulthood, and finally old age, the programme offers a visually-stunning insight into how our bodies function. Throughout life we undergo a continuous second-by-second transformation, every move we make and every outside stimulus triggers a reaction through the skin, bones, organs, muscles and cells. We breathe on average 700 million breaths in a lifetime, an adult skeleton is replaced every seven to 10 years, we shed as many as 30,000 dead skin cells every minute, and the food we eat travels 30 feet on its journey through our bodies. The Living Body takes you beneath the skin to reveal how our bodies evolve from birth to old age, and the amazing biological systems we need to thrive. Embark on an incredible journey tracing the story of one everywoman using milestones to examine the everyday workings of a living, functioning body in ways not seen before. Cutting-edge miniature endoscopic HD cameras delve deep inside the mouth, throat, heart, lungs, digestive tract, brain and reproductive organs to shed new light on how and why our bodies do what they do. Stunning photography reveals universal moments in human development at the most minute level, providing insight into both our own individual metamorphosis and our shared human experiences.
