SHS3 Biomedical Science · Semester 2 Week 2: Diseases and Disorders

Lesson notes

Learning Objectives

Indicator: 3.2.2.LI.4 - Describe the function of an angiogram in diagnosing blocked vessels and discuss the risk factors for heart disease.

By the end of the lesson, learners can:

Describe what an angiogram is and explain how it helps doctors identify blocked or narrowed blood vessels in the heart.
Identify and explain at least five major risk factors for heart disease, including modifiable and non-modifiable factors.
Interpret sample angiogram images and point out areas where vessels appear blocked or narrowed.
Justify why each identified factor increases a person’s risk of developing heart disease, using knowledge of cholesterol, LDL and HDL from previous lessons.
Discuss how knowing one’s risk factors can inform personal lifestyle choices and decisions about seeking medical care.

Structuring Talk for Learning: Learners identify blocked vessels on sample angiograms or angiogram images. Then learners list the risk factors for heart disease and share their opinions about why they think the listed factors are risk factors.
Teaching and Learning Resources:
