the upper chambers of the heart. The right atrium receives deoxygenated blood and the left receives oxygenated blood

the lower chambers of the heart that receive blood from the atria before pumping it out to the body/lungs

structural feature that prevents backflow of blood

the process of adding oxygen to a system, such as the bloodstream or muscle tissue

A practical exploration of the pathway of blood

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 blood vessels carries blood at high pressure?

to go to the lungs to exchange carbon dioxide for oxygen and return to the heart

to go to the lungs to expel oxygen and take in carbon dioxide

to remove carbon dioxide from the working muscles

to help clot the blood when we get a cut or graze

Why does blood travel in the pulmonary circuit?

Blood is pumped out of the left ventricle into the {{ }} before heading off around the body.

the heart's chambers have valves between them

pumps blood out into the pulmonary circuit

carries blood back into the right side of the heart

requires more oxygen from the bloodstream during exercise

enable gaseous exchange between the alveoli and the bloodstream

carries blood from the heart to the lungs and back to the heart

Match up the following key components of the circulatory system.

Blood returns to the right side of the heart via the vena cava.

Blood enters the right atria and is pumped down into the 

right ventricle before being ejected through the 

pulmonary artery which carries the blood to the 

lungs where carbon dioxide is exchanged for

Place the following sequence of events in the correct order starting with deoxygenated blood at the muscles.

Which of the following blood vessels carries blood away from the heart?

Blood is pumped out of the heart into {{ }} that carry the blood at high pressure.
