the number of times the heart beats per minute (bpm)

the volume of blood pumped out of the heart by each ventricle with each beat (measured in millilitres, ml)

the volume of blood pumped per minute by each ventricle of the heart (measured in litres per minute, l/min). Calculated as heart rate x stroke volume

The relationship between heart rate, stroke volume and cardiac output

Physical education

Double circulatory system and structure of the heart

Blood vessels and blood cells

A practical exploration of the pathway of blood

Air pathway from the atmosphere to alveoli and gaseous exchange

The mechanics of breathing

A practical exploration of how the cardio-respiratory systems work together

This unit will examine the structure and function of both the cardiovascular and respiratory systems. It includes the correct anatomical names and location of different chambers, valves and blood vessels as well as the pathway of air through to the alveoli and how gaseous exchange occurs.

Anatomy and physiology: the cardio-respiratory system

When we start to exercise our heart {{}} increases.

Which of the following is a representation of the strength of cardiac contraction?

Which of the following is an average value for heart rate at rest?

The resting heart rate of a well trained individual is typically {{}} than an untrained individual.

the number of times the heart beats per minute

the amount of blood pumped by the heart with each beat

the volume of blood pumped out of the heart per minute

the force exerted by the blood on the blood vessel walls

Match the following key terms and descriptions.

heart rate response to steady state exercise

stroke volume response to exercise for untrained person

stroke volume response to exercise for a trained person

cardiac output response to exercise for untrained person

cardiac output response to exercise for trained person

Match the following changes in response to exercise with the correct reasoning.

What is the sequence of events that make up the heartbeat called?

The contraction phase of the heartbeat is known as ...

The relaxation phase of the heartbeat is known as ...

the sequence of events in a heartbeat (contraction and relaxation)

the force exerted by the blood on blood vessel walls

a specialised type of involuntary muscle found in the heart

the contraction phase to pump blood out of the heart

the relaxation phase for the heart to fill with blood

the muscular wall dividing the left and right sides of the heart

Match the following key terms with the function.

The relationship between heart rate, stroke volume and cardiac output
