Lesson Plans

Chapter 9 — Circulation: The Cardiovascular and Lymphatic Systems

Goals of the Lesson:

Cognitive: The student will be able to identify the structure and function of the cardiovascular and lymphatic system, in its normal and clinical aspects. They will also learn different disorders, medical terms, and medical abbreviations involving the cardiovascular and lymphatic system.

Motor: The students will be able to identify the various structures on models of the heart. They will also be able to identify the location of the lymphatic structures.

Affective: The students will gain understanding of the complexity and interrelationship of the cardiovascular and lymphatic system.

Learning Objectives:

The lesson plan for each objective starts on the page shown below.

In-Class Activities
1. Pin an unlabeled poster of the heart to a large soft board. Divide the class into small teams. Randomly distribute labels of the heart to each team. Ask a person from each team to go to the poster and pin the label at the correct position. Give the team points for correctly labeling the parts. If the person gets the label wrong, the label is passed on to the next team.
Materials
