Maggie Skyler External Brain Assignment 3 Chapter 2: Histology 1. Four Types of Primary Tissues and Function Type of Primary Tissue Function Epithelial Tissue Lining Epithelial Cells -the outer layer of the skin (Lacombe) -the inner surface of the digestive and respiratory cavities (Lacombe) -the inner surface of the heart and blood vessels(Lacombe) -the walls and the organs of the closed ventral body cavities(Lacombe) -the ducts of the exocrine glands(Lacombe) Glandular Epithelial -makes up most of the glands within the body(Lacombe) (Lacombe) http://www.zoology.ubc.ca/~bioma nia/tutorial/tuthisto/ep01.htm Covering Epithelial -Protect underlying tissues against physical damage, drying out, chemical injury, and infection. (Lacombe) -Allows and regulates the passage of materials (diffusion, absorption, filtration, secretion, and excretion) into and out the deeper tissues of the body which is what they cover or line. Oxygen, water, food, and waste must pass through one or more of the epithelial layers. (Lacombe) -Specialized parts of these form sensory parts of the organs, such as the eye, ear, mouth (taste buds), and nose (olfactory epithelium). (Lacombe) Most Glands -Come from epithelial tissues that are made for producing secretions(Lacombe) -This is usually water fluid like secretions like salts, enzymes, hormones, mucus, fats, etc. (Lacombe) -Milk, insulin, bile, sweat, saliva, calcitonin, and tears are all made by glands in the body. (Lacombe) Connective Tissue -cells of tissue that are farther apart separated by extracellular material(Lacombe) Binding, supporting, and packaging -hold epithelia, muscle, and neural tissue are supported, surrounded, and held in place by it.

External Brain Assignment 3 Chapter 2: Histology -they can be found everywhere in the body(Lacombe) (Lacomb e) http://www.zoology.ubc.ca/~biomania/tutorial/t uthisto/ct01.htm (Lacombe) -form capsules and membranes around organs, form ligaments, and tendons these bind bones together and muscles in the body(Lacombe) -form 3-d fibrous mesh that support cells in organs like the liver and spleen -bone and cartilage hold organs in the body together(Lacombe) -areloar connective tissue makes soft packing around these organs (Lacombe) Protect, Defend, and Repair - regenerate fast and important in repairing after injury(Lacombe) -scar tissue occur from this tissue because the original cells do not grow back(Lacombe) -cellular and molecular defend against bacteria and chemical substances(Lacombe) -a defensive mechanism at an injury sight is inflammation(Lacombe) -skull is boney tissue that protects the brain(Lacombe) Insulation -fat cells cushion body organs, insulate them, and provide reserve sources of fuel(Lacombe) Transportation -blood carries and delivers oxygen and nutrients to the tissues of the body(Lacombe) Muscle Tissue -Cells that are made for the active generation of force for contraction.
