Homeostasis and Disease

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

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
Pandemics

Pandemics

The word pandemic comes from Greek and means “pertaining to all people”. At the end of 2019, the infectious disease covid-19 was discovered. It then spread all over the world, which had enormous consequences for millions of people. In this...Show More
Maintaining Homeostasis

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

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
What Is Homeostasis?

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
Forests

Forests

In this video, we learn about forests, one of the world’s biggest biomes. We’ll start by discussing what a forest really is - because it’s a lot more than just trees! The forest is in many ways a key resource, above all for the climate,...Show More
5 Critical Habitats

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
Transportation of Water and Minerals in Plants

Transportation of Water and Minerals in Plants

Life Processes: Transportation

Plants require water and minerals for proper growth. Root hair absorb water through osmosis, and minerals using energy from the soil. Water and minerals pass through the inner root cells and enter the xylem of the roots, from where they travel...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
How Cells Work Together

How Cells Work Together

Understanding Life Systems: Cells

In unicellular organisms, the single cell performs all life functions. In multicellular organisms, cells are organised into tissues, organs and organ systems. A group of similar cells that work together to perform a specific function is called...Show More
The Importance of pH in the Human Body

The Importance of pH in the Human Body

Acids, Bases, and Salts

The pH in the human body tells about the value of the acidity or basicity of an aqueous solution. Acidity produced in the stomach, due to overeating, can be reduced by having an antacid, like the syrup milk of magnesia.
Fats

Fats

Components of Food

Fats are the nutrients which provide almost double the amount of energy as compared to carbohydrates. All types of oils and nuts, butter, milk and meat are excellent sources of fats. When eaten in excess, fats get stored in the liver, under the...Show More
