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.
Athletes demonstrate their flexibility in this look at our ingeniously designed muscular-skeletal system. Discusses muscle and bone interaction, their structure, purpose, and function. Comments on technological studies on motion.
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.
An expert on exercise physiology discusses the importance of different elements of fitness, and teenagers share personal stories about how exercise helped them achieve and maintain a healthy weight. Exercise also helps build strength, develop endurance, improve agility, boost self-confidence, and connect socially. John Ratey, a professor of psychiatry, describes the growing evidence that aerobic exercise remodels our brains, making us sharper mentally, and providing protection against mood disorders. Teens describe how exercise helped them deal with depression, anxiety, and stress.
Speech, your means of communication, is the medium for exchanging ideas and expressing both pleasure and pain. Examines the physiology of speech by looking at humans' vocal tracts. Shows how the larynx, vocal chords, wind pipe, tongue, and lips produce the sounds of speech. Also, looks at the ability to understand speech by explaining why your ears and brain can discern the subtle nuances of rapid sounds.
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.
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.
Students receive a crash course in the physiology and functioning of their hearts as well as how to keep their hearts healthy. Animations clarify how the heart works to provide oxygen and nutrients to all the tissues and organs of the body. They also detail what can go wrong. The program stresses that even teenagers can show early signs of atherosclerosis and other heart problems. Two cardiologists and a dietitian then pinpoint the main risk factors for an unhealthy heart, including: smoking, abnormal levels of cholesterol, high blood pressure, obesity, diabetes, and physical inactivity.
The hummingbird has a forked tongue that is lined with hair-like extensions. Its design is especially useful for drinking nectar from flowers.
Natural selection is a mechanism of evolution. In this episode, Pinky and Petunia discuss the relationship of natural selection and antibiotic resistance in bacteria. Part of "The Amoeba Sisters" series.
Shows what happens to a boy's body during puberty, and what to expect from the physical and emotional changes that accompany it.
Through easy-to-understand examples, this video helps students grasp how sounds are formed and how sound travels. Special attention is given to the different characteristics of sounds and how humans sense sounds.
Special attention is given to the healthy maintenance of growing bodies. Concepts and terminology discussed include: body systems, cells, tissues, organs, health, and body needs.
Scientist Bruce Jackson traces ancestry and solves crimes with the powerful tool DNA. Part of the Scientists and Engineers On Sofas Series.
Shows what happens to a girl's body during puberty, and what to expect from the physical and emotional changes that accompany it.
Speciation is the evolutionary process by which populations evolve to become distinct species. Topics covered in this episode include sympatric and allopatric speciation, as well as several different types of isolation. Part of "The Amoeba Sisters" series.
Dr. Ronald Evans reviews how cell receptors called PPARs regulate body weight by controlling fat burning or storage. Part of the 2004 Howard Hughes Holiday Lecture Series.
Students demonstrate the relationship between taste and smell.
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.
How does eye color work? Get ready for a long look deep into the genetics and physics of eye color. Part of the "It's Okay to Be Smart" series.
