Which chamber of the heart pumps oxygenated blood to the body?
Right Atrium
Right Ventricle
Left Atrium
Left Ventricle
Which blood vessel contains valves to prevent backflow?
Arteries
Veins
Capillaries
Aorta
Which of the following is NOT a component of blood?
Plasma
Platelets
Nephrons
Red Blood Cells
What is the main function of the cardiovascular system?
Digestion
Movement
Transport of oxygen, nutrients & waste
Breathing
True or False: Vasodilation means blood vessels get wider.
True
False
Where does gas exchange occur?
Bronchi
Bronchioles
Alveoli
Diaphragm
Which of the following is NOT part of the respiratory system?
Trachea
Bronchi
Diaphragm
Kidneys
VO₂max measures:
Maximum strength of your muscles
Maximum oxygen your body can use
Maximum blood volume in the heart
Maximum number of breaths per minute
During exercise, what happens to breathing rate and tidal volume?
Both decrease
One decreases, one increases
Both increase
Both stay the same
True or False: The respiratory system helps maintain pH balance by removing CO₂.
True
False
Why does blood flow redirect during exercise?
To keep the body warm
To send oxygen to working muscles
To help digestion
To store energy
Which of the following helps regulate body temperature during exercise?
Sweating
Increased blood flow to skin
Neither
What happens to heart rate during exercise?
Stays the same
Increases
Stops
Decreases
True or False: Acute responses to exercise help meet the body’s increased oxygen demands.
True
False
What happens to resting heart rate after long-term exercise training?
It decreases
It increases
It stays the same
It becomes irregular
Which adaptation increases cardiac efficiency?
More blood vessels in the stomach
Greater stroke volume
Reduced red blood cells
Smaller lungs
Which of the following is a long-term adaptation of the respiratory system?
Shorter breaths
More lactic acid
Slower gas exchange
Improved lung capacity and efficiency
Faster recovery after training happens because:
Muscles shrink
Lungs hold less oxygen
Cardiovascular & respiratory systems adapt
The heart stops working as hard
Which adaptation best improves endurance performance?
Increased bone density
Increased VO₂max and stroke volume
Lower sweat rate
Less blood circulation
True or False: Long-term adaptations improve both performance and endurance.
True
False
Discuss the physiological changes to the respiratory system when exercising at a maximum level.
