Summary

Cell organisation

In a nutshell

Many organisms are made up of lots of cells. In order for an organism to function properly, these cells must be organised.

Tissues

Definition

A tissue is a group of similar cells that work together to carry out a specific function.

Example

Epithelial tissue is made up of epithelial cells, which cover specific parts of the body like the inside of the gut.

Organs

Definition

An organ is a group of different tissues that work together to perform a specific function.

Example

The epithelial tissues that line the inside of the gut work with muscle tissues. They make up the stomach, which is an organ.

Organ systems

Definition

An organ system is a group of organs that work together to perform a function.

Example

The digestive system consists of the mouth (1.), salivary glands (2.), oesophagus (3.), stomach (4.), small intestine (5.) and large intestine (6.). These organs work together to break down and absorb food for energy.
