Unit 3 Lecture Study Guide

1. List the 4 primary tissue types and give the general characteristics and functions of each one.

Epithelial tissue covers the body surface and form linings for internal cavities, serving functions such as protection, secretion, absorption and filtration with the three types being thin, flat to cubic to enlonged. Connective tissue is the most abundant type and distributed wildly, providing functions such as support and protection. Examples include fat tissue, cartilage, bone and lymph. The three types of muscle tissue are skeletal, smooth, cardiac. Nerve tissue is composed of specialize cells that receive stimuli and conduct impulses to and from the body, nerve cells are long and stringlike.

2. How are epithelial tissues classified?

The three classifications are squamous epithelium which have cells wider than tall, cuboidal epithelium which has cells of equal width and height and columnar epithelium havee cells that are taller than they are wide.

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 diffusion, filtration and lining. This is found in the blood and lymphatic vessels, alveoli of lungs and lining of serous membrane. cuboidal epithelium is 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 the brain. Columnar epithelium is found in the glands, bronchioles of lungs, uterus and intestines. It is used for secretion and absorption.

4. Differentiate between exocrine and endocrine glands. Give an example of each.

Endocrine glands secrete products to the bloodstream directly, controlling homeostasis and metabolism. Example is pituitary gland and pineal gland. Exocrine gland secrete products via ducts, it can either be external or internal and an...
