Which one of the following is not a function of the cardiovascular system
Regulates body temperature
Removes waste products
Production of red and white blood cells
Transports oxygen
What is the function of the pulmonary and systemic circuits?
In the pulmonary circuit the blood travels from the right side of the heart to the lungs. In the systemic circuit blood travels from the left side of the heart to all body parts.
In the pulmonary circuit the blood travels from the left side of the heart to the lungs. In the systemic circuit blood travels from the right side of the heart to all body parts.
What valve prevents blood going back into the right atrium?
Tricuspid valve
Pulmonic valve
Aortic valve
Mitral valve
Oxygenated blood travels back to the heart and enters the left atrium via the (a)
When the right ventricle contracts and pumps oxygenated blood, what takes it to the lungs?
(a)
What happens in the capillaries to help get rid of waste products?
(a)
What is the only vein which does not transport deoxygenated blood from the body to the heart?
(a)
Heart rate is the number of what per minute?
(a)
What is stroke volume?
Amount of blood pumped from left atrium per heartbeat.
Amount of blood pumped from right ventricle per heartbeat.
Amount of blood pumped from left ventricle per heartbeat.
What is the equation for working out cardiac output?
(a)
When blood is being pumped faster stroke volume will increase. What will this also increase?
venules
capillaries
blood pressure
What increases in the blood when the skeletal muscles work harder?
(a)
Does vasodilation...
increase blood to an area
restrict blood flow to an area
When the heart becomes larger, thicker and stronger muscular walls this is known as cardiac (a)
Which one of the following terms, A, B, C or D, is being described in the statement below?
The volume of blood leaving the heart per beat
Maximum cardiac output
Stroke volume
Cardiac output
Heart rate
Which chamber of the heart contains oxygenated blood and when it leaves that chamber it enters the Aorta?
Right Atrium
Left Atrium
Right Ventricle
Left Ventricle
Which chamber of the heart contains deoxygenated blood and has just entered this chamber from the Vena Cava ?
Right Atrium
Left Atrium
Right Ventricle
Left Ventricle

According to the World Health Organisation which of the following blood pressure readings is classified as optimal?
160/100
120/80
130/ 60
80/120
Why is it important that we are able to redistribute blood?
The brain sometimes need more oxygen to concentrate more
Allow more blood to get to the skin to release heat during exercise
Our organs don't need any oxygen during exercise
It helps us to eat during training
Define tidal volume
The amount of air left in the lungs after a maximal breath out
Total lung capacity
The amount of air breathed in and out in one minute
The volume of air inspired and expired in one breath
What is minute ventilation?
Breathing rate x tidal volume
Volume of oxygen used in 1 minute of exercise
How much air a ventilation machine gives you in 1 minute
The extra amount of oxygen your muscles need during exercise
One feature of veins is that they contain one-way valves. Identify one other feature from the list below:
Carry blood away from the heart
Walls are one cell thick
Most carry deoxygenated blood
Have permeable walls
Veins contain one way valves to prevent...
(a)
The bicuspid valve makes sure that...
blood doesn't flow back from the right ventricle to the right atrium
blood doesn't flow back from the left ventricle to the left atrium
blood doesn't flow back from the aorta to the left ventricle
blood doesn't flow back from the pulmonary artery into the right ventricle
oxygenated and deoxygenated blood don't mix
How many blood vessel types do humans have?
4
5
3
2
Human blood vessels are
artries, capillaries, and atria
ventricles, atria and pulmonary veins
capillaries, artries, and veins
veins, artries, and aorta
Define cardiovascular system
the interaction of the heart and lungs to supply oxygen to muscle during exercise.
to do with the heart, blood and blood vessels working together.
when veins swell up or dilate; widening of the lumen of the blood vessel to allow for increased blood flow.
when veins shrink down; narrowing of the lumen of the blood vessel to decrease blood flow.
Define vasodilation
the interaction of the heart and lungs to supply oxygen to muscle during exercise.
to do with the heart, blood and blood vessels working together.
when veins swell up or dilate; widening of the lumen of the blood vessel to allow for increased blood flow.
when veins shrink down; narrowing of the lumen of the blood vessel to decrease blood flow.
Define vasoconstriction
the interaction of the heart and lungs to supply oxygen to muscle during exercise.
to do with the heart, blood and blood vessels working together.
when veins swell up or dilate; widening of the lumen of the blood vessel to allow for increased blood flow.
when veins shrink down; narrowing of the lumen of the blood vessel to decrease blood flow.
Which is not a function of the cardiovascular system
transport oxygen, carbon dioxide and nutrients.
Helps blood to clot.
It controls body temperature
protection of vital organs.
The left side of the heart is
oxygenated
deoxygenated
both
Arteries carry blood
at high pressure to the heart
at low pressure away from the heart
at high pressure away from the heart
at low pressure to the heart
Define vascular shunting
Process that increases blood flow to active areas during exercise and away from inactive areas.
a red protein in the blood that transports oxygen; found in red blood cells.
a transparent cell known as a leukocyte. And is the bodies defence system against pathogens (cause of disease/illness)
A chemical that destroys a pathogen.
Define haemoglobin
Process that increases blood flow to active areas during exercise and away from inactive areas.
a red protein in the blood that transports oxygen; found in red blood cells.
a transparent cell known as a leukocyte. And is the bodies defence system against pathogens (cause of disease/illness)
A chemical that destroys a pathogen.
What is a the role of blood plasma
the fluid part of blood responsible for circulation of cells and nutrients.
production of thrombokinase (substance involved in blood clotting).
the structures and processes in your body that stop disease.
hormone that triggers the clotting process.
