Lesson notes

Learning Objectives

Indicator: 3.2.1.LI.3 - Describe how the interconnectedness of the body systems aid in energy generation.

By the end of the lesson, learners can:

Trace the pathway of energy generation from food intake through digestion, absorption, and circulation to the point of energy release in cells.
Describe how the digestive, circulatory, and respiratory systems work together to supply the raw materials (glucose and oxygen) needed for cellular respiration.
Measure and compare heart rate variations among group members using palpation, and explain the factors that account for these differences.
Explain the specific role of the cardiovascular system in delivering digested nutrients and oxygen to tissues while removing carbon dioxide and other wastes.
Predict what would happen to energy generation if any one of the three systems (digestive, circulatory, or respiratory) failed to function properly.

Curriculum details

Strand: Human Body Systems (Strand 2)
Sub-strand: Anatomy and Physiology (2.1)
Content standard: 3.2.1.CS.1 - Demonstrate an understanding of the interconnectedness of the body systems in energy generation and use (digestive, circulatory and musculoskeletal systems). 3.2.1.LO.1 Describe the role of enzymes digestion and explain how water and oxygen is transported the cardiovascular and respiratory systems.
Indicator: 3.2.1.LI.3 - Describe how the interconnectedness of the body systems aid in energy generation.
Suggested placement: Semester 1, Week 13 (Week 13 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Activity-Based Learning: In mixed-ability groups and using stethoscopes or palpations, learners note the variations in heart rate among group members.
Talk for Learning: Brainstorm on why heart function varies and describe the factors that can cause heart function variability.
