Study Guide for Anatomy and Physiology
Unit 3 Lecture Study Guide
1. List the 4 primary tissue types and give the general characteristics and functions of each one.
Epithelium- The epithelium protects us from the outside world. Skin, absorbs. Stomach and intestinal lining, filters. The kidney, secretes. Forming of glands, closely attached to each other forming a protective barrier, always has one free surface open to outside the body or inside an internal organ, has no blood vessels but can soak up nutrients from blood vessels in connective tissue underneath, always had one fixed section attached to underlying connective tissue, and can have lots of nerves in it.
Connective Tissue- The connective tissue runs through organ capsules and deep layers of skin giving strength, wraps around and cushions and protects organs, internal support of organs, as tendon and ligaments protects joints and attached muscles to bone and each other, stores nutrients, ground substance, fibers, cells.
Nervous Tissue- The nervous tissue conducts impulses to and from body organs via neurons, brain, spinal cord, nerves.
Muscle Tissue- The muscle tissue is responsible for body movement, moves blood, food, waste through body’s organs, responsible for mechanical digestion
2. How are epithelial tissues classified?
Size and shape the number of cell layers, shape of the cells, whether the cells are ciliated or unciliated.
3. How does the type of epithelial tissue relate to its function? Give at least 1 example of where you would find each type of epithelial tissue.
Squamous epithelium is used for filtration, diffusion, and lining. It is found in the blood and lymphatic vessels, alveoli of lungs and lining of serous membrane. Columnar epithelium is found in the glands, bronchioles of lungs, uterus and intestines. It is used for secretion and absorption. Cuboidal epitheliums are found as a cube, and are used for secretion and absorption. It is found in the kidney tubules, glands and ducts, as well as the choroid plexus of
