Organs
Biology: AQA GCSE Higher, topic 2.1.2
Organs
Organs are groups of distinct tissues that work together to perform a specific function. An example of an organ is the stomach. The stomach contains the following tissues:

Muscular tissue
- Muscular tissue moves the contents of the stomach around during digestion.

Glandular tissue
- Glandular tissue produces digestive juices that break down the stomach's contents.

Epithelial tissue
- Epithelial tissue lines the stomach.

Why does the stomach contain both muscular tissue and glandular tissue?
What would happen if a tissue in the stomach stopped working?
