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 how different systems work together in the homeostatic mechanisms of thermoregulation and osmoregulation.

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 processes ensure that blood glucose and carbon dioxide levels are maintained at normal levels. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

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 role that homeostasis plays in the functioning of cells, organs and body systems by regulating temperature, nutrients, electrolytes and oxygen.

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 passages, and explains the role it has in ensuring blood flow around the body. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

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, nephrons and renal pyramids, and explains its function as part of the urinary system. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

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, explaining key terms such as steady state, negative feedback loop and set point. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

In this episode, we look at how electrical equipment is designed to use the right amount of current for the voltage supply that it's designed for. After a brief recap on electric current, we look at what voltage is and how it is measured. we then look at the concept of resistance. At a simple level, some materials are conductors and some materials are insulators, but not all conductors conduct equally well. The amount of current that flows in a household appliance depends on the appliance's resistance Show Less

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 critical danger because we humans are rapidly destroying them. This programme seeks to explain why these five habitats are very important to life in the sea and to point to the fact that they are all in decline. They are being damaged by human activity... some are being cleared away for ports or housing, some are damaged by trawling nets or dredge silt, as well as pollution, overfishing, or the slow but undeniable outcomes of global warming... to name only a few of the reasons. We need to try and stop this worrying trend. Show Less

The terrestrial zone is the area of land around the pond that is not regularly inundated with water.
