Part 1 Circulatory & Respiratory Systems Test
Study Guide
Please read through this sheet and make sure you are familiar with ALL terms you
see! 
*Make sure these terms are in your blue folder: tissue, organ, circulatory system, system,
heart, respiratory system, diaphragm, lungs, trachea
Heart Box Diagram – Be able to label the following: four parts of the heart – Right atrium
Right ventricle, left atrium, left ventricle
When you look at the diagram – be able to identify which part is the “body” and which is the
“lungs”
When you look at the diagram - be able to take blue/red color pencils and draw the pathway
of blood
Circulatory System Blood Pathway
Remember the blood is DEOXYGENATED (OXYGEN POOR) (BLUE) from the BODY to the
HEART – it goes to the right atrium to the right ventricle then out to the LUNGS – at the lungs
the blood picks up OXYGEN, now the blood is OXGENATED (RED) (OXYGEN RICH) – blood
travels back to the heart enters the left atrium then the left ventricle and leaves through the
AORTA - and goes to the rest of the BODY. 
Larry – Diagram of the Respiratory System – Be able to label the following parts:
bronchioles, bronchi, larynx, trachea, nose/nasal cavaties, mouth, lung
Important info about - The Heart – It has four chambers.
Atriums Receive blood
Ventricles Pump blood
Arteries take blood AWAY from the heart.
Veins carry blood TO the heart.
Respiratory System Pathway
Air moves into your nasal cavaties/mouth to your larynx to the trachea to the bronchi to
the lungs to the bronchioles.
Questions

What prevents dirt and dust from entering your lungs? – Mucus
What’s another name for the trachea? Wind pipe
What is the name of a disease common in children that involves the lungs? – Cystic Fibrosis
Find the answers! 
What is gas removed from your blood, what gas is absorbed?
Why are your lungs important?
