1121 - What is a system of organs made of in the body of an animal

A system of organs in the body of an animal is made up of different types of tissues. These tissues are made up of groups of cells that work together to perform specific tasks.

Think of it like this:

• Cells are like individual workers
• Tissues are like groups of workers doing a specific job (like muscles or skin)
• Organs are like teams of workers (tissues) that work together to do a bigger job (like the heart pumping blood)
• Systems are like big teams of organs that work together to keep the whole body working (like the circulatory system with the heart, blood vessels, and blood)
