Acting as the body’s control centre, the brain is responsible for all the essential functions of the body. This dissection of a sheep’s brain, complemented by clear, illustrative diagrams, looks at the brain’s two hemispheres and their four...Show More
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
