- Animal organs
- Large multicellular organisms develop systems for exchanging materials. During the development of a multicellular organism, cells differentiate so that they can perform different functions
- A tissue is a group of cells with similar structure and function. Examples of tissues include:
- Muscular tissue- which can contract to bring about movement
- Glandular tissue- which can produce substances such as enzymes and hormones
- Epithelial tissue- which covers some parts of the body
- Glandular tissue- which can produce substances such as enzymes and hormones
- Muscular tissue- which can contract to bring about movement
- Organs are made of tissues. One organ may contain several tissues. The stomach is an organ that contains:
- Muscular- to churn the contents
- Glandular tissue- to produce digestive juices
- Epithelial tissue- to cover the outside and the inside of the stomach
- Glandular tissue- to produce digestive juices
- Muscular- to churn the contents
- Organ systems are groups of organs that perform a particular function
- The digestive system is one example of a system in which humans and other mammals exchange substances with the environment. The digestive system includes:
- Glands- such as the pancreas and salivary glands, which produce digestive juices
- The stomach and small intestine- where digestion occurs
- The liver- which produces bile
- The small intestine- where the absorption of soluble food occurs
- The large intestine- where water is absorbed from the undigested food, producing feaces
- The small intestine- where the absorption of soluble food occurs
- The liver- which produces bile
- The stomach and small intestine- where digestion occurs
- Glands- such as the pancreas and salivary glands, which produce digestive juices
