Circulatory
System
Vocabulary
 Alveoli – Air sacs that make up the lungs
 Atrium – top chamber of the heart
 Blood Vessel – a tube that transports blood
and materials throughout the body
 Cardiovascular Disease – a disease that
affects the blood, blood vessels and/or heart
 Gas Exchange – taking in one gas while
dropping off another
 Heart – organ that pumps blood throughout
the circulatory system
 Ventricle – lower chamber of the heart
Function
Oxygen

Nutrients
Waste
dioxide and _________
to various parts of the
body
Heart:

Body
from the _______

Oxygenated
 Left Atrium: receives ________________
blood
from the __________
Lungs
Body
 Left Ventricle: sends blood to the __________
Parts
_________
 Septum – Wall that separates the right and left
sides of the heart
 Valves – separate the atria and ventricles

Cardiovascular Diseases:
Platelets
 Hemophilia: not enough _____________
to
clot blood
High
 Hypertension: __________
blood pressure
Thickening
 Atherosclerosis: ____________
of the inner
Heart attack
lining of the arteries, can cause ___________
____________
or Stroke, limit cholesterol
intake…fried foods
Cardiovascular Diseases:
 Sickle cell Anemia: sickle shaped _________
Red
blood cells
 Leukemia – a type of
cancer that causes an
increase in the number of white blood cells
Gas Exchange
 The Circulatory system gives carbon dioxide
to the alveoli (lungs) to be exhaled out of the
body
 The respiratory system inhales oxygen and
gives it to the circulatory system to be
transported to the cells throughout the body
6th Grade Review – Energy Resources
 Renewable resources don’t run out or can be
replaced in your lifetime
ex. Solar, Wind, Running Water, Wood (trees)
 Nonrenewable resources take millions of
years to form and are in a limited supply
ex. Coal, Oil, Gasoline
 Nonrenewable resources need to be
conserved and used sparingly by recycling
and reducing the use (ex. Carpooling, Mass
transit)
