Drag the terms on the left to the appropriate blanks on the right to complete the sentences. 1. The epithelial membrane that lines the closed ventral cavities of the body.
2. The epithelial membrane that lines body cavities open to the exterior membrane
3. Consists of keratinized stratified squamous epithelium.
4. Found lining the digestive and respiratory tracts.
5. Makes up the pleura and pericardium.
6. Lines blood vessels and the heart.

Some of these sentences both refer to the same term.

1. The epithelial membrane that lines the closed ventral cavities of the body.  - 5. Makes up the pleura and pericardium. This is called the serous membrane.

2. The epithelial membrane that lines body cavities open to the exterior membrane . - 4. Found lining the digestive and respiratory tracts.  These statements refer to the mucous membrane.

3. Consists of keratinized stratified squamous epithelium.  - cutaneous membrane.

6. Lines blood vessels and the heart. - endothelium.

Explanation:

All of these membranes are formed by epithelial tissue - one of the four basic tissues found in the human body, with important tasks that many times give the organs they're part of their main function.

The epithelium can vary in shape and size in order to adapt to the necessities of the organ. If the organ needs protection from abrasions, like the skin or the stomach, this tissue will have many layers and be called "stratified epithelium". On the other hand, an organ with the function to exchange substances, like the blood vessels or the alveoli, will have only one layer of epithelium, to ease the diffusion of gases and other molecules.

The other three basic tissues are: connective tissue, muscle tissue, and nervous tissue.
