Objective:
Achievers on the ROAD to college learn
more extensively about the respiratory
and circulatory systems and the tissues
that make them
The
BIG
ideas
1. Structure determines
function.
2. Cells are the building
blocks of life.
3. Our health and
survival depend on the
interactions of our cells.
Let’s start our notes.
Please take out a sheet of lined paper
and write.

Respiratory and Circulatory Sytem
We have 5 KP’s today.
• KP1: The function of the
respiratory system is to breath
in oxygen and get rid of carbon
dioxide
– In normal breathing, we easily
breathe in oxygen and breathe out
carbon dioxide.
– This process is known as gas
exchange which occurs in the
lungs
• KP2: The lungs and trachea are
the major organs in the
respiratory system
• KP3: Oxygen pathway:
Oxygen enters from the
nasal/mouth cavity  pharynx 
larynx  trachea  bronchi 
alveoli
• KP4: The functions of the
circulatory system is to:
1.
2.
3.
transport materials to and
from cells such as oxygen,
nutrients and wastes
Fights infection
Helps control body
temperature

circulatory system is to:

2.
3.
transport materials to and
from cells such as oxygen,
nutrients and wastes
Fights infection
Helps control body
temperature
• KP6: The main organs
are the heart and the
blood vessels!
• These blood vessels help
carry the nutrients to
your cells and remove
wastes from your cells
KP7: How are the respiratory and
circulatory systems related?
• Heart pumps blood into the lungs where gas
exchange occurs when the alveoli release the
carbon dioxide from the body and takes in oxygen
 Oxygenated blood is then returned to the heart
and the newly oxygenated blood is circulated to
the rest of the body.
• The circulatory system then transports the oxygen
blood to cells in our tissues where the oxygen is
used to help burn fuel!
How are the respiratory and circulatory
systems related?

Answer in your own words:
1. What is the function of the
respiratory system?
2. What is the function of the
circulatory system?
3. How are the respiratory and
circulatory system related (how
do they work together)?
