Total questions: 18
Worksheet time: 12mins
During exercise, what happens to cardiac output?
Decreases as heart rate increases
Increases up to about 60% max HR and then levels off
Increases linearly throughout (increasing at a predictable rate)
Represents the amount of blood reaching working muscles
When blood vessels at the muscle sit vasodilate, what happens to the blood vessels at the major organs?
Less blood is directed towards the muscles
More blood is directed to the brain and heart
Vasodilation will also occur at major organs
Vasoconstriction occurs at vessels supplying major organs
Which blood vessel primarily supplies blood to most of the body?
Superior vena cava
Pulmonary vein
Pulmonary artery
Aorta
What is the main function of plasma?
Transport red blood cells via the vascular system
Remove wastes
Regulate body temperature
Do all of the above
What are likely symptoms of hyperthermia ? (Select two)
Rapid pulse
Slow pulse
Shivering
Cramping
What is a common symptom of hyporthermia?
Uncontrolled shivering
Slow and shallow breathing
Body temperature over 40 degrees
A pulse that is rapid and bounding and breathing that is fast and deep
How does vasoconstriction of the muscles affect an athlete's performance?
It decreases blood flow and reduces performance
It increases blood flow and enhances performance
It has no effect on performance
It temporarily boosts cognitive functions
What color is used to represent oxygenated blood in a diagram showing blood movement between the heart and lungs?
Red
Blue
Green
Yellow
What is the primary purpose of a three-day acclimatisation camp for athletes?
To increase team spirit and cohesion
To adjust to new time zones
To adapt to higher temperatures and humidity
To practice new strategies
Why is 'blood boosting' prohibited by WADA?
It is considered a natural method of performance enhancement
It can cause long-term health issues
It provides an unfair competitive advantage
It is less effective than other methods
What is one potential harm that could be detrimental to athletes using practices to boost their red blood cell count?
Increased energy levels
Improved hydration
Risk of blood clots
Enhanced flexibility
Oxygenated blood travels through the...
Through the pulmonary vein > into the left atrium > left ventricle > and out of the aorta to the rest of the body.
Through the pulmonary artery > into the left atrium > left ventricle > and out of the aorta to the rest of the body.
Through the pulmonary artery > into the left atrium > left ventricle > and out of the vena cava to the rest of the body.
De-oxygenated blood travels through the...
Through the pulmonary vein > into the left atrium > left ventricle > and out of the aorta to the rest of the body.
Through the vena cava > into the right atrium > right ventricle > and out of the Pulmonary artery > to the lungs
Through the vena cava > into the left atrium > right ventricle > and out of the Pulmonary vein > to the lungs
What is the primary function of white blood cells in the circulatory system?
To carry oxygen to tissues
To regulate blood pressure
To fight infections
To clot the blood
What is stroke volume?
The volume of blood pumped out of the left ventricle of the heart during each systolic (lowest) contraction.
is the amount of blood the heart pumps per minute
The volume of blood pumped out of the left ventricle of the heart during each systolic (largest) contraction.
is the amount of blood the heart pumps every 15 seconds.
What is cardiac output?
The volume of blood pumped out of the left ventricle of the heart.
is the amount of blood the heart pumps, measure by litres per minute
The volume of blood pumped out of the left ventricle of the heart during each systolic (largest) contraction.
is the amount of blood the heart pumps every 15 seconds.
What makes up the cardiovascular systme?
The heart, ribs, and muscles.
The hearts, Lungs, and blood.
The heart, muscles and organs.
The heart, blood vessels and blood.
What is NOT a main functions of the cardiovascular system?
To transport nutrients, gases and waste products around the body.
To protect the body from infection and blood loss. And maintains fluid balance.
the body getting rid of carbon dioxide and inhaling oxygen.
To help the body maintain a constant body temperature ('thermoregulation')
