The human excretory system is explained in this animated video. They will learn to identify the different organs, the roles that they play in the filtering toxins from blood, and the creation and excretion of urine.

Respiratory System

Internal respiration and external respiration are described. Clear explanations and graphics, show that internal respiration is the exchange of oxygen and carbon dioxide between the blood and the cells of the body (other than the lungs), and that external respiration is the exchange of gases between the air and blood in the lungs. The video resource details the anatomy involved in breathing, and goes on to look at what causes snoring and sleep apnoea.

Circulatory System

This animation features the heart and circulatory system and how they work. Mayo Clinic, USA.

Homeostasis is a term first defined by Claude Bernard in 1865 it means maintaining a constant internal environment this is a bit like car brain works senses all around the body imaging various things and sending the information back to the brain the brain in does its best to keep all these things stable and constant to keep the body working properly. FuseSchool - Global Education

Homeostasis is an important regulatory system that allows organisms to maintain internal stability and metabolic efficiency within variable external environments. This program introduces the phenomenon of homeostasis, why it is important and how it works.


A "sense" is how your brain perceives stimuli going on around it in the external world. As a kid, you probably learned that we had five of them (sight, smell, hearing, taste, and touch), but the reality is that we've got a lot more. How many senses do you think we actually use on a daily basis? Science Plus

This animated video that explains the process of perception, the senses and how the nervous system works in presence of different stimuli.
