Answer ALL questions.
The numbers in brackets in the right-hand margin indicate the provisional allocation of
maximum marks per sub-section of a question.

All drawings should be your own work. It is recommended that they are hand drawn with
pencils/pens, but you may use a computer stylus or mouse.
Where possible text answers should be typed.
You are expected to spend no more than 3-4 hours on this assignment.

SECTION A [20 marks total]
1) Draw a diagram of the two main body cavities, labelling them and their main sub-
divisions. For each subdivision name an example of an organ it houses.
[8 marks]
2) With reference to the three stages of haemostasis, deduce why:
a) a newly formed blood clot is soft and fragile, whereas after a few hours it is
relatively tough.
b) a severe artery bleed (e.g. due to traumatic amputation), may initially display
minimal blood loss, but the rate of bleeding may suddenly increase an hour or more later.
[6 marks]
3) The peripheral nervous system is divided in to two systems, responsible for voluntary and
involuntary control. Name these two systems. For each, give an example of where it is used,
and why it is the appropriate control system for that body part.
[6 marks]

focus on the muscular-skeletal and cardiovascular systems.
a. Draw and label a human hip joint, showing, alongside other appropriate details:
i. The internal structure of a long bone
ii. Two opposing muscles.
(1-3 diagrams may be used)
[7 mark]
b. Muscles and tendons are essential for the movement of the joint. Explain the
difference between tendon, ligament and muscle and describe the mechanisms for
the movement to take place.
[6 marks]
c. Deduce the theoretical changes to the structures, drawn in question 4a, due to long
term lack of exercise, with the vast majority of each day spent sitting. Describe how
these changes develop, and explain your logic1.
[6 marks]
d. Consider the exercise plan (figure 4.1, spans 2 pages). Evaluate it with respect to its
suitability for maintaining heathy cardio-vascular and muscular-skeletal systems in a
fit young adult, temporarily confined to a one room flat.
[4 marks]
e. How and why would you modify the plan for the following user groups (general
principles, detailed exercise plans are not required):
i. People aged over 70
ii. Children aged 5-10
iii. Pregnant women (2nd trimester)
[7 marks]

1 Note: your answer should be based on logical deductions based on what was taught in the course, and show
a biomedical engineering perspective. Do not conduct a literature search, as this is likely to be unhelpful. For
example, a past paper asked students to deduce some of the impacts of sickle cell anaemia, from a diagram
showing ŚŽǁ͕ŝŶƚŚĂƚĚŝƐĞĂƐĞ͕ƌĞĚďůŽŽĚĐĞůůƐĂƌĞƐƚŝĐŬŝĞƌƚŚĂŶŶŽƌŵĂů͙ƐƚƵĚĞŶƚƐǁĞƌĞĞdžƉĞĐƚĞĚƚŽƐŚŽǁƚŚĞ
following logic: sticky cells -> blood clots->blocked blood vessels-> heart attack or stroke. A literature search
would not have given them this answer, as [fortunately] these extreme effects are very rare, whereas effects
which are harder to deduce are common.

7 Intense Workouts You Can Do in Small Spaces

exercise into these spaces feels like a lost cause Ͷ especially when it comes to any kind of
workout that will actually show results. But often, due to our hectic schedules, these
locations are the only places we can hope to sneak in a workout. And as research has shown

30-second break between each set.

against the wall and slide down until your hips, knees, and ankles are all making right angles
with the floor. Hold this for as long as you can bear it, then let yourself rest for 10 seconds.
Try doing three to five more squats to really reap the benefits of this simple, yet effective,
move.
3. High-knee sprints

the whole move Ͷ run in place and drive your knees just above your hips. To get the most
out of this exercise, put your hands with palms down in front of you and try to hit them with
your kneecaps. Or, you could try pumping your arms with perfect 90-degree angles to elevate
the cardio level. Also, to avoid any injury, make sure you land on the balls of your feet rather
than your heels. Do this for 30 seconds followed by 20 seconds of rest. Then, repeat three to
five times.
4. Chest press

have access to a resistance band and door, you can get a great chest workout even with
limited space. Lock your resistance band to the door and then stand facing the other
direction, placing one side of the band in either hand. Point your toes forward, bend your
knees slightly, and engage those core muscles. Bend your arms at 90 degrees with your upper
arms parallel to the floor and then straighten your arms by pushing them forward. Repeat
this move 15 times.

5. Butt kickers
For another option to (for lack of a better term) kick your butt into shape, go for this cardio
ŵŽǀĞ͘/ƚ͛ƐƉƌĞƚƚLJƐĞůĨ-explanatory Ͷ essentially, you just run in place. But instead of driving
your knees up, you kick your heels to (or near, to avoid some nasty bruises the next day) your
butt with every stride. Just like with high-knee sprints, do three 30-second sprints with 20
seconds of rest in between, and repeat three to five times.
6. T push-up against a wall
Once again taking advantage of the walls as equipment, try this next-level version of a push-
up. Start by getting into regular push-up position while standing against the wall. Your body
should be parallel and a couple of inches away from the wall. Then, rotate the back of your
torso toward the wall and raise your other hand into the air. Keep your arms straight and press
the back of your raised hand against the wall, holding it for five seconds. Go back to your
original position, then replicate in the opposite direction. Repeat this move 10 times on each
side.

Your friend will be traveling to an area prone to river blindness, and has been asked to
bring a supply of disease prevention tablets, for a secondary school. The children will
need between 1 and 4 tablets, depending on their height.
e) For the example of a class of 100 children aged 14, explain how the UK Boys growth
chart (Figure 5.2) can be used, with the dosage table (Table 5.15.1), to estimate the
number of tablets required. You should show the steps needed, and explain the
reasoning, using data from the chart but you are NOT required to calculate the final
numerical answer.
