Valve
Function of the Septum Cardiac muscle that divides the left and right side of heart
Function of Purkinje Fibres Carry nerve impulses to ventricles to ventricles to aid contraction
Function of the Inferior Vena Cava Carries deoxygenated blood from the lower body to the heart

Atria Contract (Atrial Systole) which forces AV valves open and blood moves through
Step 2 of Blood Flow (deoxygenated)
to fill ventricles
Step 3 of Blood Flow(deoxygenated) AV Valves close shut to prevent backflow
Step 4 of Blood Flow (deoxygenated) Ventricles contract (Ventricular Systole) - increases pressure
The pressure causes semilunar valves to open and blood flows into pulmonary
Step 5 of Blood Flow (deoxygenated) arteries (deoxygenated) The pressure in arteries closes the SL valves to prevent
backflow.
The process for deoxygenated is reversed.
What happens to the process of blood
Blood enters from Pulmonary Veins, into Left Atrium and is forced through to Left
flow for oxygenated blood?
Ventricle through the Bicuspid Valve. The ventricle contracts and forced blood
through the Sl Valve into the Aorta where it is pumped around the body.
The formulae for cardiac output? Cardiac Output = Heart Rate X Stroke Volume
The process of pumping blood around the heart, once oxygenated blood is
What is the Cardiac Cycle?
received from lung.
Blood drains from Left Atrium from Pulmonary Vein. This is cardiac diastole (heart
Step 1 of the cardiac cycle
fills with blood).
Step 2 of the cardiac cycle The raising of blood pressure in Left Atrium forces Bicuspid Valve to open.
The contraction of Left Atrium (atrial systole) forces blood through the AV valve into
Step 3 of the cardiac cycle
the Left Ventricle.
When the Left Ventricle is full (Ventricular Diastole) the ventricles contract
Step 4 of the cardiac cycle
(Ventricular Systole).
The pressure caused by Ventricular Systole causes AV Valve to shut and causes SL

valves to open. Blood is forced up into the Aorta.
What happens to the right side of the heart The process is exactly the same for deoxygenated blood.

cells in a narrow lumen.
The Structure of Capilliaries Very thin wall with a small lumen.
A thin wall, with very little smooth muscle or elastic fibres. The lumen is wide and
The Structure of Veins
there are valves.
To withstand high blood pressure as they carry blood away from heart. They must
be able to change the diameter of lumen with the blood flow. The walls must be able
Function of Arteries
to stretch when blood is pumped through and be able to recoil back to size.
Therefore the surface must be low friction.
There needs to be rapid exchange (diffusion etc) between blood and tissues hence

Be able to pump blood to heart under low blood pressure. They do not stretch
Function of Veins or recoil due to low bp. They act as a reservoir so have a large volume. Valves
prevent the backflow of blood.
