BIOSC-116 Lecture Notes - Lecture 6: Epithelium, Smooth Muscle Tissue, Cardiac Muscle
Document Summary
Our dna has many different set of instructions and each set is our genes. Some may be on and active within a cell type will depend on which type of cell it differentiates to. Directs them into specific cell types that we find within our body (muscle cells, blood cells, nerve cells, epithelial cells, etc) Each type of cell has a different set of genes that are active. Epithelial tissue covers body surfaces, lines cavities (e. g. chest, abdomen), lines hollow organs (e. g. stomach) and ducts (e. g. hollow organs (e. g. stomach) and ducts (e. g. blood vessels) and forms glands. On your body or within your body (your skin is covering your body, the lining of your mouth, lining of your organs, all lined with epithelial tissue) Preventing things from getting out of structures. Skin prevents infections from getting in, prevents us from drying out, etc. To keep substances in or to protect other substances from getting in.
