the volume of air breathed in or out during normal breathing

the additional volume of air that can be forcefully inhaled after a normal inhalation

the additional volume of air that can be forcefully exhaled after a normal exhalation

the amount of air that remains in the lungs after maximal expiration

Mechanics of breathing and interpretation of a spirometer trace

Physical education

The structure of the heart

Blood vessels, blood cells and the vascular shunt

A practical exploration of the pathway of blood

The cardiac cycle

The relationship between heart rate, stroke volume and cardiac output

Air pathway from the atmosphere to alveoli and gaseous exchange

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

Which of the following terms refers to breathing in?

the ribs move up and out while the diaphragm flattens down.

the ribs move down and in while the diaphragm flattens down.

the ribs move down and in while the diaphragm moves into a dome.

the ribs move up and out while the diaphragm moves into a dome.

The {{}} muscles help pull the rib cage down and in faster when exhaling during exercise.

additional air that can be forcefully inhaled after a normal breath in

additional air that can be exhaled after a normal exhalation

the volume of air that remains in the lungs after maximal exhalation

Match the following key terms with the correct description.

the intercostal muscles and diaphragm contract.

the ribs move up and out whilst diaphragm moves down and flattens.

air rushes into the lungs from the atmosphere.

Arrange these key processes in the correct order to represent what happens when we breathe in.

Which of the following **additional** muscles are recruited to aid expiration during exercise?

The process of switching oxygen for carbon dioxide is known as {{}} exchange.

the windpipe that connects the larynx (voice box) to the bronchi

two main branches off the trachea that lead to the lungs

tiny air sacs in the lungs where gaseous exchange occurs

the movement of molecules from higher to lower concentration

gases moving from high to low partial pressure

air being forced out of the body by blowing hard

Which of the following does not describe the process of diffusion?

Arrange these body parts in the correct order of inhaled air starting at the atmosphere.

Gaseous exchange happens between the {{}} and the bloodstream thanks to large capillary networks.
