PART 1: RESPIRATORY SYSTEM
Activity 1
Directions: Identify what is being described in each statement. Write your answer on the
space provided before the number.
______________________1. It is also called a voice box.
______________________2. It is also known as the throat.
______________________3. It allows gas exchange in the lungs.
______________________4. This is a flat muscle that pulls and pushes the lungs.
______________________5. These are the finer subdivisions of the bronchi to the lungs.
______________________6. This is the organ where the air enters and is filtered.
______________________7. It is a hollow tube that serves as passageways of air into the lungs.
______________________8. These are tubes that take air into the lungs and remove carbon
dioxide.
______________________9. It serves as a channel for airflow through the nose in which the air
warmed, cleaned and moistened.
______________________10. These are pair of organs in the chest that are primarily responsible
for the exchange of oxygen and carbon dioxide between the air we breathe and the
blood.
Activity 2
Directions: Arrange the following statements to show how air enters in the human body.
Write numbers 1 to 5.
______1. The diaphragm helps the air go in and out of the lungs.
______2. When you breathe out or exhale, the diaphragm muscle relaxes.
______3. When you breathe in or inhale, the diaphragm muscle contracts.
______4. The bronchi subdivide many times inside the lungs, forming the hair-like tubes
called bronchioles.
______5. Air enters the body through the nose, nasal passages, and then through the
windpipe or trachea, which divides into two branches called bronchi.
PART 2: CIRCULATORY SYSTEM
Activity 3
Directions: Identify the parts of the circulatory system being described. Write your answer
on the blank.
1. It pumps the blood throughout the body. ______________
2. It carries the blood throughout the body. ______________
3. It carries deoxygenated blood to the heart. ______________
4. It carries oxygen and other materials throughout the body. ______________
5. The smallest blood vessels in the body and the actual site where gases and nutrients are
exchanged

Activity 4
Directions: Fill in the blanks with numbers 1-7 to show how blood flows in the heart.
_________A. The blood gets oxygenated in the lungs.
_________B. Oxygenated blood goes back to the heart through the pulmonary vein.
_________C. The blood moves in the right atrium and gets through a tricuspid valve.
_________D. The blood flows in the right ventricle and travels to the pulmonary artery.
_________E. The left ventricle pumps the blood throughout the body through the aorta.
_________F. The left atrium receives the oxygenated blood and passes through the mitral
valve.
_________G. Deoxygenated blood passes through the superior vena cava and inferior vena
cava.
Activity 5: Respiratory and Circulatory Works Together
Directions: Arrange the JUMBLED letters and identify the words that will help you trace how
the respiratory and circulatory systems work together.
_____________1. The SUNGUL takes in oxygen from the breath.
_____________2. The oxygenated blood then enters the chamber, the FELT MURTIA.
_____________3. Then the oxygenated blood will be pumped to the aorta through the FELT
NETRIVLEC.
_____________4. After supplying the oxygen to the cells, the deoxygenated blood enters
another chamber called GIRTH MURTIA.
_____________5. The GIRTH NETRILEC then pumps the deoxygenated back to the lungs to
get oxygen again.

Activity 6
Directions:
