Cardiac output gradually decreases as they get used to the exercise load
Stroke volume and submaximal heart rate gradually decrease
Stroke volume and submaximal heart rate gradually increase
Which of the following correctly describes the sequence of excitation of heart muscle?
AV node → bundle of HIS → SA node
SA node → AV node → bundle of HIS
bundle of HIS → SA node → AV node
AV node → SA node → bundle of HIS
What is the chemical composition of a glucose molecule?

Which of the labels for the lever system are correct?
Effort: Y, Fulcrum: Z, Load: X
Effort: Z, Fulcrum: X, Load: Y
Effort: X, Fulcrum: Y, Load: Z

Which of the following defines momentum?
force × time
velocity × time
mass × velocity
mass × distance
Which of the following describes Newton’s second law of motion?
The rate of change of momentum of a body is proportional to the force causing it.
To bring about motion a force must be applied.
When one body applies a force to another the second body will apply an equal and opposite force back.
The effect of a constant force on a mass will always be the same.

Y is a region of lower relative air velocity and lower relative air pressure
X has lower relative air velocity and Y has higher relative air pressure
X is a region of lower relative air velocity and higher relative air pressure
