Instructor’s Name: Khady Guiro
Course Title: Anatomy and Physiology
Chapter: 3
Topic: Tissue diversity—Epithelial tissues
Grade Level: 12
Instructional Objectives
In this lesson, students will learn about one of the four types of tissues: the epithelial tissues. The
main parts of the lesson are the different structures of the epithelial tissues, their primary
locations in the body, and their main functions.
Inclusion
1. Students will be given a brief review about the organization level of the human body: Cells
organize into tissues, tissues organize into organs, organs are organized into organ systems, and
organ systems are organized to make up the organism.
2. Students will also be given a power point presentation of the topic, followed by hands on
laboratory activity.
3. Students are also expected to take notes and complete their worksheets.
Key Points
1. How to classify the epithelium (Simple, cuboidal, stratified, and glandular)
2. Characteristics of epithelial tissue types
3. Functions of the epithelial tissues
Do Now Questions
1. Write down the names of as many organ systems as you can and name the different cell types.
Opening
A brief review of an overview of the organization of life is given to the students. The five levels
of life will be explained, and the students will fill the important information into an outline.
Introduction
Cells have the ability to live independently providing they have a source for heat, nutrients, and
the appropriate gas for respiration. In multi-cellular organisms, individual cells do not have to
control all aspects of their survival. Instead, different cell types are capable of performing
specialized key functions. For instance, cells associate to form tissues, and tissues associate to
form organs. The organs associate to form living organisms. This lesson gives the student the
ability to understand how cells associate with each other to form tissues in order to help the
entire organism survive. The specific tissue topic is the epithelial tissues. Epithelial tissues
are formed from cells which join together to form covering layers, for example, the skin covering
the body. This type of tissue also forms the covering layers of various organs in the body; the
lining of the body cavities and the active parts of the glands of the body. Epithelial tissues are
made up of specialized cells of various shapes and are joined in different ways as shown.
Students will also be introduced to current research on skin: Apligraft.
Guided Practice
After the power-point lesson, students will use the microscopes which will be already set up in
the classroom. For this in class assignment, students will identify and clearly describe the
different subcategories of epithelial tissues under the microscope. By now, students have already
done the microscope laboratory, so using the microscope this time around will be much easier.
Then the students will complete their worksheets.
Closing
Students will swap their handouts, and the answers will be gone over. Then the class will discuss
other organ systems and how the different parts work together to maintain the body’s
homeostatic balance.
Independent Practice
Students will complete their worksheets, and answer to the analysis questions in their lab
handouts.
Differentiation
Accommodations:
Students who need help with the microscope will be helped individually.
Assessment
Assessment would be based on students understanding of the concepts and not on vocabulary
memorized. All students will be evaluated on their Independent practice assignment as well.
Homework
Students will be given the homework handout which will be due at the beginning of the
following class.
