Unit 4 PBS Heart

Unit 4: The Human Heart

Students examine the normal function of the human heart and investigate malfunctions in the cardiovascular system that can lead to heart disease. Students complete a dissection to tour heart anatomy and study heart function using probes and data acquisition software. They collect and analyze heart data including heart rate, blood pressure, and EKG readings and analyze cardiac test results of Anna Garcia. Students explore the role cholesterol plays in the body. Students further their knowledge of molecular biology as they run gel electrophoresis and complete RFLP analysis to diagnose familial hypercholesterolemia. Students design models to simulate the function of a pump and design visuals to show interventions for blocked coronary vessels.

Arteries carry OXYGENATED blood and are usually red -AND-Veins carry DEOXYGENATED blood and are usually blue.

PULMONARY Arteries that lead from the heart to the lungs carry deoxygenated blood to the lungs -AND-
