the combined functions of the cardiovascular system or heart and blood vessels and the respiratory system or lungs and airways

the process where oxygen and carbon dioxide are transferred between the alveoli in the lungs and the bloodstream via capillaries

the execution of an action or the ability to achieve a task effectively and efficiently

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

Physical education

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 substances does the human body need to extract from the air to provide energy for movement?

A by-product of aerobic respiration is {{ }} which is expelled from the body when we breathe out.

Arrange these components of the respiratory system in order from the atmosphere to the bloodstream.

Gaseous exchange happens at the muscle tissues.

Oxygen moves into the bloodstream at the alveoli.

Carbon dioxide moves into the bloodstream at the alveoli.

Gaseous exchange occurs when oxygen or carbon dioxide move from areas of high to areas of lower {{ }} via diffusion.

Arrange these components of the circulatory system in the correct order for the pathway of blood from the lungs to the working muscles and back to the lungs via the heart.

Which of the following terms refers to breathing out?

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 up into a dome.

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

Which of the following does diastole refer to?

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

the number of times the heart beats per minute

the amount of blood ejected from the left ventricle per beat

the amount of blood pumped out of the heart per minute

the amount of air breathed in or out per breath

Match the following key terms and descriptions.

Gaseous {{ }} is the process where gases move from high concentration to lower concentration.
