The endocrine system maintains the body's delicate chemical balance. Describes the location, function, and effects of the major endocrine glands, and notes their close relationship to the nervous system. Some discussion of diabetes and hormonal imbalances.
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.
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.
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.
Diagram of the internal view of the female reproductive system. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.
Investigates the major body systems that are important during physical activity: the skeletal, muscular, cardiovascular, respiratory, and nervous systems. Examines each of these systems, their parts, their functions, and how they work. Also, explores the contribution and interaction of the systems when we exercise and while we are rest.
Research in biology would be impossible without a common framework for grouping and distinguishing species. Carl Linnaeus was the first to propose a classification system of organisms. His system developed into the organizational structure used in the life sciences today. Viewers also learn how new scientific names are created and how the existing system has been further refined using DNA studies.
This video explores the wide range of defense mechanisms the body calls upon to fight foreign invaders in an effort to maintain health. Immune responses, diseases, and care of the immune system are some of the topics addressed. Concepts and terminology include: pathogen, defenses, lymph, phagocytes, macrophages, lymphocytes, humoral immunity, antibody, acquired immunity, vaccines, allergies, autoimmune disorders, AIDS, immune disorders, and care of the immune system.
The immune system has a tough job keeping human bodies free of harmful microbes. Humans come in contact with germs and bacteria every day, and the immune system is challenged to protect the body. Explores how the human body goes to battle against germs in order to keep people healthy and how sometimes the immune system requires assistance.
The body's best offense against microorganisms is its immune system. But what is it and how does it work? Why does it sometimes work against us? Discusses the non-specific (skin, tears, saliva, mucus, stomach acid) and specific (lymphatic system, spleen, thymus, bone marrow) defenses that keeps us healthy. Describes some autoimmune diseases and various marrow-produced cells.
Students learn and explore the major features of the skin, skeletal, and muscular systems. Special attention is given to the care and maintenance of skin, skeletal, and muscular systems. Concepts and terminology include: integumentary system, layers of skin, sweat glands, bone, osteocytes, periosteum, marrow, cartilage, ossification, types of joints, ligaments, types of muscle tissue, and voluntary and involuntary muscle.
Focuses on comets, those mostly unpredictable, wandering objects in the solar system. Uses time-lapse images while explaining a comet's tail and the meteors, or "falling stars," associated with it. Mentions Halley's and Hale-Bopp comets and international efforts to see these bodies more closely. Contains actual pictures of comets photographed by space probes.
Explores the need for many multicellular plants to have specialized internal transport systems, which are systems that can efficiently distribute materials from soil and leaves to the parts of the plants where they are needed. An overview of how plants obtain their nutrients is provided. The structure and function of root hairs is explored, explaining their remarkable ability to facilitate an enormous uptake of water and dissolved minerals for the plant. Following this, the separate transport systems of the xylem and phloem are explored in detail. Also explains the mechanisms by which vascular plants transport water and minerals upward from the roots as well as sugars from leaves and other sugar sources throughout the plant for storage or for growth and repair.
Satellite footage, telescopic photos, and animation are used to teach students about the many aspects of the solar system. Viewers are introduced to ancient astronomers, telescopes, observatories, and space exploration. Students will discover facts about planets, orbits, gravity, revolution, and rotation. The program also features discussions of the sun, comets, asteroids, and meteors. Part of the Real World Science series.
Discover what happens at the outer edges of the solar system where solar wind interacts with interstellar space. The Interstellar Boundary Explorer (IBEX) is a mission to study the boundary between the solar system and interstellar space. It collects data that shows the global structure and dynamic nature of the heliosphere.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term solar system. Part of the Science Video Vocab Series.
Shows the human body systems: lungs, heart, and skeleton. Demonstrates the structures of the lungs, heart, and arteries and veins. Explains exchange of gas in the lungs, ventilation of the lungs, and how the heart works as a pump. Also discusses the role of the skeleton in providing support, protection, and anchorage for muscles, the importance of bone marrow, and the importance of calcium in giving strength to bones.
What are asteroids? Where are they? Are they dangerous to us? Explores this space body, its place in the solar system, and its potential threat to life on Earth. Discusses the LINEAR Project, which identifies and maps asteroids. Notes that meteorites are pieces of asteroids, and shows where both have hit Earth.
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.
Examines Mercury, the closest planet to the Sun. Uses photography from the Mariner fly-bys and animation to show the planet's surface features. Describes its characteristics, length of day vs. length of year, its two sunrises, and its orbit. Time-lapse images record Mercury passing across the Sun, an event that occurs only 13 times a century!
