Tutorial Exercises (To be completed during the tutorial session)
1. Please refer to Figure 1, a diagrammatic representation of sagittal and transverse cross-
sections of the heart.
Identify unlabelled structures.
Figure 1: Human heart cross-sections
2. Please refer to Figure 2, which shows a drawing of an unidentified closed human heart
valve.
Identify the structures and relate structure to function.

a. What is the function of valves in the heart?
b. The valve shown in Figure 2 is closed. Identify the structures labelled X and Y, and
briefly describe their functions:
c. What is the name of this valve? Explain your answer.
d. Why are structures X and Y not present on all heart valves?
3. In preparation for the World Cup, Cristiano Ronaldo, sleeps in a low oxygen environment
(a hypoxic tank with 15% O2 saturation). Why do you think his coaching/medical team would have recommended this?

Student Name: ______________________________________ Student ID: _________________________ 5
Suggest other possible ways for Cristiano to achieve the same result?
4. David Letterman has just been diagnosed with life threatening arrhythmia. What is
arrhythmia?
As his cardiologist, what possible interventions would you recommend and why?
After undergoing the recommended procedure, David receives a long list of restrictions to his postoperative activities. One of the points on that list states;
“Do not move your elbows higher than your shoulders for 4 weeks after the surgery.”
Why do you think this is important? What are the possible consequences for David if he decided not to follow these instructions?
