Homeostasis and Disease

Homeostasis

Homeostatic imbalances, which occur when feedback loops are broken or altered, can have very serious, or even fatal, consequences. This video covers diabetes, hyperthyroidism and hypothyroidism, explaining in detail how they result from...Show More

Body Systems and Homeostasis

Homeostasis

Body systems, particularly the nervous and endocrine systems, play an important role in maintaining homeostasis and they are highly developed in mammals. This video investigates the role of body systems in maintaining a steady state, detailing...Show More

Maintaining Homeostasis

Homeostasis

Homeostasis is required for healthy functioning and is achieved when the conditions within the body are in a steady state. This video looks at homeostasis and dynamic equilibrium in the human body, explaining step-by-step how homeostatic...Show More

The Impact on Body Functions

Homeostasis

Homeostasis maintains internal conditions so that cells can function normally, fundamentally contributing to survival and good health. This video looks at homeostatic processes in single-celled and multicellular organisms, explaining the critical...Show More

Ovine Heart

Dissections for the Science Classroom

The central component of the circulatory system, the heart plays a vital role in moving nutrients and waste around the body. This dissection of a sheep’s heart shows the structure of the organ, including its chambers, veins, arteries and...Show More

Porcine Kidney

Dissections for the Science Classroom

The kidneys play a vital role in the body by filtering blood, removing wastes and producing urine. This dissection of a pig’s kidney shows the structure of the kidney, including the renal artery and vein, the renal pelvis, cortex and medulla,...Show More

What Is Homeostasis?

Homeostasis

Homeostatic processes occur in a range of organisms, enabling them to withstand a wide range of changes in the external environment. This video covers the basic facts about homeostasis with a focus on thermoregulation in the human body,...Show More

5 Critical Habitats

Life in the Sea

In the sea life is everywhere, but five habitats are like underwater cities. They are coral reefs, mangroves, salt marshes, sea grass beds and kelp forests. They provide safety, food, and a nursery for the young of many species. Yet they are in...Show More
The Terrestrial Zone

The Terrestrial Zone

The Pond: Community Ecology in Action

The terrestrial zone is the area of land around the pond that is not regularly inundated with water. This video looks at biotic and abiotic factors in the terrestrial zone, discussing the flora and fauna found in this zone and the potential...Show More
The Littoral Zone: Food Chains and Food Webs

The Littoral Zone: Food Chains and Food Webs

The Pond: Community Ecology in Action

The organisms found in the littoral zone are critical for the biological cycling of abiotic factors. This video explores the complex relationships between primary producers, lower level consumers and higher order consumers and how they can be...Show More
The Limnetic Zone

The Limnetic Zone

The Pond: Community Ecology in Action

The euphotic and profundal zones, which together comprise the limnetic zone, are home to a variety of organisms. This video looks at the characteristics of primary producers and consumers and how energy is transferred and lost through the...Show More
The Benthic Zone

The Benthic Zone

The Pond: Community Ecology in Action

The benthic zone teems with life and biodiversity and acts like the digestive system of the pond. This video explains how organisms here have adapted to living in conditions of low light and low oxygen and why they are crucial for processes of...Show More
The Littoral Zone: Photosynthesis

The Littoral Zone: Photosynthesis

The Pond: Community Ecology in Action

The plants found in the littoral zone play an important role in maintaining and supporting the biotic and abiotic conditions of a healthy pond. This video explains how these plants photosynthesise, looking at the role reeds and rushes play in...Show More
The Still Water Pond

The Still Water Pond

The Pond: Community Ecology in Action

A pond is an ideal place to see how living and non-living things interact with each other and their environment. This video introduces key aspects of pond ecosystems, explaining how abiotic factors define the four pond zones and how relationships...Show More
Functions of the Human Skeleton

Functions of the Human Skeleton

Systems of the Human Body: Skeletal System

The skeleton plays a crucial role in all vertebrates, including humans. This video introduces viewers to the role of the human skeleton, covering the key functions of shape, movement, protection, blood cell production and mineral storage....Show More
Bone Health and Disease

Bone Health and Disease

Systems of the Human Body: Skeletal System

There are many diseases, both historical and still widespread today, that are related to the health of our bones. This video discusses rickets, spina bifida, scoliosis, osteoporosis and arthritis, explaining their causes and methods of treatment...Show More
Injuries and Healing

Injuries and Healing

Systems of the Human Body: Skeletal System

Knowing what bones are made from is essential for understanding what happens when they break and mend. This video guides viewers through the minerals and proteins in bones and the two types of bone tissue, then explains the various...Show More
Joints and Movement

Joints and Movement

Systems of the Human Body: Skeletal System

The points at which bones connect with each other, or the joints, are critical for the body’s range of movement. This video explains the structural and functional classifications of joints, providing detailed descriptions and examples of...Show More
Structure of the Skeleton

Structure of the Skeleton

Systems of the Human Body: Skeletal System

The human skeleton contains up to 206 bones, arranged in a particular structure to fulfil their unique functions. This video comprehensively covers different types of bones and their function, the axial and appendicular skeletons and includes a...Show More
Land and Ocean

Land and Ocean

Shedding Light on the Sun and Earth

"Land and Ocean" examines who the world's land masses and oceans affect global climate patterns. We look at why the air gets colder and colder the higher you go, why coastal regions don't heat up or cool down as much as inland regions, why...Show More
The Coriolis Effect

The Coriolis Effect

Shedding Light on the Sun and Earth

In this episode, we describe how tropical cyclones form and examine their huge power. We explain what the Coriolis effect is and how it make tropical cyclones rotate the way that they do. We also travel to three continents to demonstrate how...Show More
Following the Sun

Following the Sun

Shedding Light on the Sun and Earth

"Following the Sun" looks at how the sun's movement across the sky every day changes. In summer, the sun reaches a much higher angle in the sky than it does in winter. This affects the design of energy-efficient homes and the placement of solar...Show More
