Smelling is as natural as breathing. Sixteen times a minute, air passes through the nose to fill the lungs. Billions of molecules passing through the nasal cavities are captured by the cells of the olfactory organ. Scientists and others are presently working in the realms of taste and smell to understand their powers. They are bringing to light the mystery that, from conception to adulthood, reveals a fabulous potential. Is it possible that one day the nose will help uncover diseases, vanquish pain, and lower stress levels? Part of the “Human + The Future of Our Senses” series.

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".

Provides a short overview of the five senses: sight, hearing, touch, smell, and taste. Explores the special relationship between taste and smell. Shows how our senses combine to help us more richly experience the world around us. Includes suggested classroom activity.
Students demonstrate the relationship between taste and smell.
Explores how POPs (persistent organic pollutants) contaminate the traditional food web of native peoples and are passed from one generation to another, causing cancer and other serious health problems. Addresses concerns such as what are government and industry doing about POPs, how do POPs affect indigenous peoples' relationship to nature, and how do POPs affect treaty rights.
Presents sensory receptors that depend on contact with the immediate world: taste buds, touch sensors, and olfactory cells. These receptors lie in the skin, the largest organ of the body, which also senses heat, pain, and pressure. Re-creates the complex world of the skin through realistic models and photographs.
Why do some birds, like raptors, move from one region to another at certain times of the year? It is all about their interactions with the environment. The primary factor is scarcity in a food source. Another factor includes changes in the weather. This episode explains the seasonal events that affect the raptor’s migration and provides a platform to investigate the types of relationships found in their ecosystem. Part of the "Seasonal Science" series.
Touch, taste, smell, hearing, and sight: the human body's five major senses. They are senses that have evolved independently over millions of years but are brought together by our marvelous central nervous system into the most refined way of interacting with the environment of any species on the planet. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of each of these sensory systems and shows how the brain uses them to produce what we call being human.
Provides an overview of all the stages to ensure a kitten grows up to become a happy, healthy, and much-loved addition to a family. Cats have an extra sense organ, and they can actually "taste" smell. In relation to their body size, cats have the largest eyes of any mammal. The cat's grace and beauty have inspired artists since ancient times. By Victorian times they became pampered pets. Cats are loving and affectionate but have an independent character that guarantees them a special place in the hearts of their caregivers. NOTE: Bonus material follows main feature.
Sight, touch, hearing, taste, and smell send sensory messages to the brain at a speed of 430km/hr. The brain deals with 11 million information signals per second, and this continual flow of information is sorted and analyzed by the brain, which directs the senses, organizes them, and improves them. The brain’s plasticity allows it to continually adapt. If and individual loses one sense, the brain reorganizes and compensates by increasing the power of the other senses. This episode highlights an artist who is blind and uses his fingers to feel the color of the paint before applying it to the canvas. Part of the “Human + The Future of Our Senses” series.
Join host Joel Greene on this adventure to learn what it’s like to be a farmer. While visiting Amy’s Farm, Greene tastes the strong arugula plant, meets a hungry pig, spots a fresh chicken egg, and gets up close and personal with a dairy cow. Part of the Curiosity Quest Series.

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. Ralphie wants to catch salmon to serve at the annual school picnic, but he can't find any at his favorite fishing spot. Where could all the salmon have gone? The kids are soon "Frizzled" inside a salmon bus that has an uncontrollable urge to head upriver. Using its sense of taste and smell, it swims the long journey to a shallow freshwater stream mile away. Why has the bus, which thinks it's a salmon, gone to all this trouble?
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko crosses the plains of Siberia and gets his first taste of the cold. After having found shelter in a cave for the night, he wakes to find a carpet of snow stretching out over the landscape as far as his eyes can see. Amazed at first, Moko realizes that he can no longer see his path and find his way. Could he have found the end of the world where distracted travelers get lost? At which point he notices footprints leading to a village.
Krypton is a chemical element with the symbol Kr and atomic number 36. It is a colorless, odorless, tasteless noble gas that occurs in trace amounts in the atmosphere.
Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko sees the sea for the first time. He thinks it is a huge river or a large lake. But when he tastes the water, it's salty. He wonders what sorcerer could have played such a dirty trick. He returns to his village and asks a wise old man to cast a spell to prevent the river used by the people from ever becoming salty. The old man assures him that it won't be necessary, that the river will never be salty. So Moko thinks that a well-meaning sorcerer must already be protecting the river--thankfully.
Remixed from Customizable Atom Delux by roman_hegglin. Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.
