Lab Stuff-Animal Tissues
Objective: We observed and identified the shape, structure, and function of animal tissues.Materials: I used a pen, paper, my lab textbook, prepared slides of cross sections and microscopes. Method: Listed to lecture, read my lab book on Animal Tissues, made drawings of the structures that we observed. Results: The different tissues observed are as follows: 1. Epithelial Tissue-forms continuous layer, or sheet, over the entire body surface and most of the body's inner cavities. Types of Epithelial Tissue: a. Simple Squamous Epithelium-a single layer of thin, flat, many-sided cells, each with a central nucleus. It lines internal cavities, the heart, and all the blood vessels and parts of the urinary, respiratory, and male reproductive tracts. It functions in filtration; diffusion; and osmosis. b. Stratified Squamous Epithelium-consists of many layers of cells. The innermost layer produces cells that are first cuboidal or columnar in shape, but as the cells push toward the surface, they become flattened. It is the outer region of the skin, the epidermis. The cells move toward the surface, flatten, accumulate keratin, and die. It also lines the mouth, throat, anal canal, and vagina. It
c. Smooth Muscle-a/ka/ visceral muscle, makes up the walls of the internal organs like the intestines and blood vessels. It is involuntary in contraction. It functions in involuntary movement of substances in lumens of body.
