The human body needs to take in food and water found in the environment, and through a sequence of mechanical and chemical processes, it converts that food into nutrients that sustain all the body's activities. The digestive tract alone has nine major organs devoted to this process, and the renal tract has three. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of the many organs and structures of digestion. Lastly, explores the properties of metabolism and nutrition.
Explores how the digestive system works and how to use the food chart to eat healthfully. Also reveals all the physiological details of the esophagus, the large and small intestines, and the stomach.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Arnold's dream comes true-- he doesn't have to go on a field trip. Ms. Frizzle lets him stay behind with Liz. However, it seems Arnold can't be completely left out because he accidentally swallows the bus. He then becomes the field trip as his classmates explore Arnold's digestive system.
Shows the crucial part water plays in the body's functioning and the system for keeping it in balance. Drinking, sweating, and breathing are covered. The urinary tract is analyzed in detail, with particular attention to the functioning of the kidneys.
Reviews appetite and hunger. Shows the actions of a salivary gland, the swallowing reflex, and the powerful churning of the stomach as food is broken down and processed.
Willy has eaten too much and has a heavy stomach. The cat invites him to practice the digestion sequence to relieve a heavy stomach. They practice the cow face, the beetle, the cosmic egg, and the child poses. Part of the "Ooommm Mmmooo Yoga For Children" series.
Willy is participating in a rally against global warming, but he has an upset stomach. The cat invites him to practice the purifying session to help with digestion. They practice the butterfly, the book, the phone, and the armadillo poses. Part of the "Ooommm Mmmooo Yoga For Children" series.
Homeostasis refers to the body’s ability to maintain a stable internal environment, and maintaining homeostasis requires that the body continuously monitors its internal conditions. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Topics covered include homeostasis, negative feedback loop, nervous system, endocrine system, digestive system, excretory system, musculoskeletal system, and the immune system. Part of the "Biology" series.
Investigates the digestive consequences when a family sits down to lunch. As the first morsel is put into the mouth, the camera watches from inside as the molars clamp down and the process of breakdown and transformation occurs. Follows the food through the entire alimentary tract, showing how it is dissolved in acid, how the liver and gallbladder work, and how digestion and absorption work.
In this program, students learn about the digestive process. The human digestive system consists of the gastrointestinal tract plus the tongue, salivary glands, pancreas, liver, and gallbladder. Digestion involves the breakdown of food into smaller and smaller components. These small components are absorbed and assimilated into the body. Part of the "Human Nutrition" series.
Part of the "Branches on the Tree of Life" series. Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain nor nervous system, and no movement as an adult. In spite of their simple nature, sponges are actually one of the most interesting animal phyla when viewed in developmental, ecological, and evolutionary terms. Clarifies the structure, function, classification, and ecological roles of sponges through animations and time-lapse microscopy.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While navigating the dense aquatic weed forest of the pond, the Cyclops is pulled off course by a hydra. After escaping its tentacles, the crew begins to study how the hydra reproduces, captures its food, and digests its prey. One of the Micronauts takes a journey inside the hydra’s digestive system to get a first-hand account of the digestive process. Part 4 of the Microscopic Monsters Series.
Anna was born with a sweet tooth, and as a young woman, she created a successful business using it. Her delicious jams and jellies gave pleasure to many, but did they also cause harm? Explores the way the human body processes food and how its long-term growth and development are shaped by eating habits. Illustrating cellular aging and its relationship to AGEs, or advanced glycation end products, a connection is drawn between the bacteria an infant must consume to build a healthy immune system and the bacteria that consume the body at death. As Anna's life draws to a close, viewers will understand that "dust to dust" is a cycle in which humans take an active part--every time they sit down to a meal.
Tongue taste areas The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system. The tongue's upper surface (dorsum) is covered in taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is the enabling of speech in humans and vocalization in other animals. The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum) that results in a groove, the median sulcus on the tongue's surface. There are two groups of muscles of the tongue. The four intrinsic muscles alter the shape of the tongue and are not attached to bone. The four paired extrinsic muscles change the position of the tongue and are anchored to bone. Do you have good taste? In this video segment, Dr. Linda Bartoshuk explores the sense of taste in humans - why we have it, and what happens when we lose it. Learn why the sense of smell is also important to our experience of food. Footage from NOVA: "Mystery of the Senses: Taste".
In this video, Pinky and Petunia discuss the 11 major organ systems in the human body. These include the integumentary, skeletal, muscular, nervous, endocrine, cardiovasular, lymphatic, respiratory, digestive, urinary, and reproductive system. Part of "The Amoeba Sisters" series.
