Unit 4A Worksheet
1) The heart circulates oxygenated blood to the systemic ____________via the aorta but this
does not include the blood which supplies the_________. The heart supplies the lungs via the
pulmonary_____________, which deliver ______________blood to the lungs to release carbon
dioxide (CO2) and pick up __________(O2). This __________-rich blood goes back to the heart
via the pulmonary____________.
2) Blood circulates away from the heart via_____________, which carry blood __________from
the__________. This blood can be deoxygenated at times and also oxygen-________ at other
times. The main point is that ___________carries blood ________from the_______.
3) Blood circulates back to the heart via____________, which brings blood back to the
__________. This blood can be __________-rich at times and also _______________at other
times. The main point is that _________bring blood ___________to the__________.
4) Oxygen-_______ blood which can be found in systemic ____________and pulmonary ______
is more of a ___________red due to the __________oxygen content. While ______________
blood found in systemic _________and pulmonary ____________is more of a ___________red
due to ______ oxygen content.
5) In the illustrations of systemic circulatory vessels, ____________and arterioles are colored
_________indicating their low / high oxygen content of the blood. The capillary ____________
are colored red to purple to _______indicating the loss of their _________ content and
increasing ___________Dioxide contend as they facilitate ________ exchange. The
__________and venules are colored blue in the systemic circulatory illustrations due to their
_______oxygen and _________carbon dioxide content. But in actuality the blood within these
vessels is always__________.
6) In the illustrations of the pulmonary circulatory system the pulmonary __________are colored
blue as they carry deoxygenate blood ________from the heart to the lungs where the capillary
network is illustrated first being blue then purple then red due to the gas exchange they
facilitate as the capillaries first get rid of the carbon dioxide and take in __________and bring
this ___________-rich blood ___________to the heart in pulmonary ________which are
colored________. But in actuality the blood within these vessels are always_________.
8) The extracellular fluids include blood __________which has more __________than lymph or
____________fluids which are fluids found _____________red blood cells, ________blood
cells and ____________that are suspended in__________. The __________in blood plasma
helps pull ____________back into the_____________.
#9 on back
9) The functions of blood are: _________________of blood gases, ___________and ________
__________, along with___________, vitamins, ___________and metabolic waste products,
along with _____________of blood pH acting as______________, also regulation of
______________by blood flow through the _________and regulation of ___________pressure
which regulates _________movement in the blood and ______________fluid, and finally
