Assessment Statements Obj.
Draw and label a diagram of the heart showing the four chambers, associated blood
6.2.1 1
vessels, valves and the route of blood through the heart.
6.2.2 State that the coronary arteries supply heart muscle with oxygen and nutrients. 1
Explain the action of the heart in terms of collection of blood, pumping blood and
6.2.3 opening and closing of valves.
3
Outline control of the heartbeat in terms of myogenic muscle contraction, the role
6.2.4 2
of the pacemaker, nerves, the medulla of the brain and epinephrine (adrenaline).
Explain the relationship between the structure and function of arteries, capillaries
6.2.5 3
and veins.
State that blood is composed of plasma, erythrocytes, leucocytes (phagocytes and
6.2.6 1
lymphocytes) and platelets.
State that the following are transported by the blood: nutrients, oxygen, carbon
6.2.7 1
dioxide, hormones, antibodies, urea, heat.

Hands-only CPR.
Your blood has oxygen in it – but it is not
getting to the brain and other organs.

Hands-only CPR keeps the blood flowing until
help arrives with the Automatic External
Difibrilator (AED). The electrical signal is
needed to re-start the heart, and we’ll learn
why this is in a little while. http://youtu.be/ILxjxfB4zNk

Call for help.
Push hard and fast to the beat of Stayin’ Alive.
Don’t stop until help arrives.

Data practice: CPR survival rates. Get started early to save a life!
These data compare compression-only CPR with
conventional CPR: neurologically favourable one-month
survival.
Population: bystander-assisted patients, transferred to
hospital by ambulance. Japan. 2005 – 2007.
Compression-only n=20,707
Conventional CPR n= 19,328
1. Compare survival rates of compression-only CPR
with conventional CPR in all cases (top graph).
1. Describe the effect of increasing time to start CPR
on survival of patients in cases of cardiac origin.
2. Calculate the difference in survival between hands-
only CPR and conventional CPR in cases of non-
cardiac origin after 7-8 minutes.
3. Compare survival rates between cases of cardiac
and non-cardiac origin. Suggest a reason for the
differences.
