Which of the following is not a layer of the heart?
Epicardium
Myocardium
Decardium
Endocardium
Where is the Vena Cava?
Click on the:
right ventricle
Pulmonary Vein
Oxygenated blood enters the heart via the
(a)
The (a) valve is situated between the right atrium and right ventricle
From the left atrium (a) blood travels down into the (b) . The blood is then pumped out through the (c) to the (d) .
Which arrow points to the Sinoatrial Node (SAN)?
D
F
A
H
The process of the heart filling with blood followed by a contraction where the blood is pumped out is called the (a)
Tick all that apply to the Sinoatrial node (3).
Located in the wall of the right atrium
Located in the centre of the atrium
Causes the walls of the atria to contract
Also known as the pacemaker
It delays the the signal acting as a buffer gate
What is the job of the atrioventricular node?
Acts as a buffer/gate to slow the signal from the SAN
Acts as the hearts pacemaker
Makes the impulse 5x stronger
From the AV node the message then runs down the Bundle of His which is located in the....
Atrial walls
Aorta
Septum & atrial walls
Purkinje fibres
At the end of the Bundle of His there are thin filaments called the (a)
The Purkinje fibres distribute the impulse causing the ...................... to contract.
Atrial walls
Ventricle
Atrium
Septum
What is the direction of the electrical impulse in the cardiac cycle?
Sinoatrial node - Purkinje Fibres - Atrioventricular node - Bundle of His
Sinoatrial node - Atrioventricular node - Bundle of His - Purkinje Fibres
Sinoatrial node - Atrioventricular node - Purkinje Fibres- Bundle of His
Atrioventricular node- Sinoatrial node - Bundle of His - Purkinje Fibres
How many chambers are there in the heart?
1
2
3
4
Which blood cells are responsible for resisting infections.
Red blood cells
White blood cells
Platelets
Plasma
Which cells make up 99% of the cells in the blood?
Plasma cells
White blood cells
Red blood cells
Platelets
Which blood vessels carry oxygenated blood?
Veins
Capillaries
Venules
Arteries
What is the primary reason that HR increases during exercise?
Delivery of more O2 to the muscles through the arteries
Delivery of more O2 through the veins
The heart needs to get more blood to the organs
The arteries need to remove more wastes from the muscle cells
The product of HR x SV is...
Vo2 max
A-V O2 difference
Cardiac output
Heart volume
Chronic adaptations are long-term physical improvements, usually due to training. A chronic adaptation of the cardiovascular system would be...
Increased HR
Increased right atrium size
Increased left ventricle size
decreased SV
Which option is an ADAPTATION to exercise?
Reduction in resting blood pressure
Increased blood pressure
Anticipatory rise
increased Heart rate
Capillarisation of skeletal and cardiac muscles is the...
decrease in number of capillaries
increase in number of capillaries
increase in maximum heart rate
decrease in maximum heart rate
Which option is an ADAPTATION to exercise?
Increased Blood Pressure
Decreased Heart Rate Recovery Time
Vascular Shunting
increased Heart rate
Cardiovascular Responses to exercise are...
Immediate/short term
Long term
Which option is a RESPONSE to exercise?
Anticipatory Rise
Cardiac Hypertrophy
Decreased Resting Heart Rate
Capillarisation
Sudden Arrhythmic death syndrome (SADS) is a genetic heart condition that can suddenly cause death in young healthy people it is caused by
the heart beating too quickly causing it to over work
not enough adrenaline being released for exercise
the hearts natural rhythm becoming disrupted and causing it to stop
the septum not separating oxygenated and deoxygenated blood in the heart
This is when your body becomes too cold with your core temperature dropping below 35°C
Symptoms are: Shivering, Confusion and Increased risk of heart stopping (In severe cases)
Hypotension
Hypertension
Hyperthermia
Hypothermia
This is the prolonged increase in body temperature, above its normal temperature of 37.5°C. It can cause Weakness, Coordination issues and Heat exhaustion
Hypotension
Hypertension
Hyperthermia
Hypothermia
