The Excretory system, mindmap and videos!!

Dear students,

Let´s try to create a mindmap of the excretory system, so that we can remember the most important parts and ideas:

Our Excretory System

The excretory system is made up of all the organs that remove waste substances from the body. These substances can include excess water and other waste substances.

Exhaling and Sweating

Our body also removes waste by sweating and exhaling. Sweat is made up of the waste water and salts that are stored in our sweat glands. When we sweat, the waste water is expelled through pores in our skin. When we exhale, we also expel waste substances.

Our cells absorb nutrients and oxygen. As a result, they produce waste substances like carbon dioxide and water. Our blood transports these waste substances to our lungs, they are

expelled when we exhale.
