BIOL 2010 Lecture Notes - Lecture 2: Loose Connective Tissue, Epithelium, Histology
Document Summary
Tissues: a bunch of similar cells that come together. Epithelial: (tables 5. 2, 5. 3: sheets of cells, functions: protection, absorption, filtration, excretion, secretion, and sensory reception (depending on the location in the body, 2 types. Covering/lining epithelium (covers and lines the inside and outside of body) Glandular epithelium (forms glands: classified off two things: number of cell layers and shape of cells. Because of its thin structure, this tissue is great for oxygen exchange. Mouth (eating something hard/sharp, multiple layers protect the mouth from cuts and bleeding when scraped) Because there are so many layers, it is great for areas that get a lot of abrasion. Ducts and secretory portions of many glands. Ducts of sweat, mammary, and salivary glands. This tissue is great for secretions, absorptions, and transportation since they are sturdy and offer protection to the tissues. This tissue is important in absorption and movement of mucous.
