Types of tissues 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, tissue which can produce substances such as enzymes and hormones ■ epithelial tissue, which covers some parts of the body. * ** *** To describe how cells, tissues, organs and organ systems are organised To compare the different types of tissues.

A: Muscular tissue Muscle is a very specialised tissue that has both the ability to contract and the ability to conduct electrical impulses. Muscles are classified functionally as either voluntary or involuntary. Questions 1. What does specialised mean? 2. What does muscle tissue can do? 3. Give an example of a muscle with contracts voluntarily and one that contracts involuntarily. * ** *** To describe how cells, tissues, organs and organ systems are organised To compare the different types of tissues.

B: Glandular tissue is involved with delivering hormones in the body. This tissue is rich in capillaries. Each cell must contact a capillary directly in order to deliver its hormone to the rest of the body. Questions 1. Give one example of where glandular tissue is found in the body. 2. Why must the glandular tissue be close to capillaries. 3. Give the name of a hormone produced by the human body * ** *** To describe how cells, tissues, organs and organ systems are organised To compare the different types of tissues.

C: Epithelial Tissue Questions 1. How are epithelial tissues specialised? What are they evolved to do? 2. Where in the body would you find epithelial tissue? * To describe how cells, tissues, organs and organ systems are organised Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed in one or more layers. This tissue is specialised to form the covering or lining of internal and external body surfaces. Epithelial tissue that occurs on surfaces on the interior of the body is known as endothelium. ** *** To compare the different types of tissues. To apply knowledge to the human digestive system
