Circulatory System Review
Which part of the human blood:
1. carries carbon dioxide, nutrients, wastes,
vitamins, minerals,
plasma
hormones and enzymes?
2. carries oxygen and carbon dioxide? rbc’s
3. is involved in blood clotting? platelets
4. helps fight disease? wbc’s
5. contains hemoglobin? rbc’s
6. is the liquid portion of the blood? plasma
Which part of the human blood:
1. is the most numerous? rbc’s
2. contains a nucleus? wbc’s
3. is biconcave? rbc’s
4. is produced in the bone marrow? rbc’s, wbc’s,
platelets
5. consists mainly of water? plasma
white
blood cell
Y
red blood cell
Identify structures X, Y, and Z.
Z
platelet
Cardiovascular diseases interfere most directly
with the normal functioning of system?
Explain the difference
between arteries and veins.
•Arteries carry blood AWAY from heart. Veins carry
blood to the heart.
•Arteries are larger, more muscular and elastic than
veins.
•Arteries carry blood under higher pressure than
veins.
•Veins have valves to prevent the backflow of blood.
Arteries do not have valves.
Explain what occurs in capillaries and why.
The exchange or diffusion of substances into or out
of the capillary.
Capillaries are extremely small and have a VERY thin
lining that allows for diffusion to occur.
The diagram represents a capillary
near some cells.
1. Identify the substances diffusing
out of the capillary and into cells.
2. Identify the substances diffusing
out of cells into the capillary.
aorta
pulmonary
artery
left atrium
vena
cava
right
atrium
pulmonary
vein
left ventricle
right ventricle
Identify the part of the heart being
described.
1. Receives oxygenated blood. Left atrium
2. Wall that separates the right and left side
of the heart. Septum
3. Large artery that carries oxygenated blood
to the rest of the body. Aorta
4. Veins that carry oxygenated blood from
the lungs back to the heart. Pulmonary veins
5. Pumps out deoxygenated blood. Right
ventricle
6. Receives deoxygenated blood. Right atrium
7. Prevents the backflow of blood between
atria and ventricles. Valves
8. Pulps out oxygenated blood. Left ventricle
9. Veins that carry deoxygenated blood
back to the heart. Vena cava
10. Arteries that carry oxygenated blood to
the lungs. Pulmonary arteries
Fill in the table below with the correct antigens
and antibodies for each blood type.
Blood Type
A
B
AB
O
Antigens
antigen A
antigen B
antigen A and antigen B
none
Antibodies
anti-B antibodies
anti-A antibodies
none
Both anti-A and
anti-B antibodies
What makes blood
type O the universal
donor?
•Type O blood does not have any antigens, so they
can be given to any blood type.
What makes blood
type AB the
universal recipient?
•Type AB blood has both A and B antigens, so they
can receive any blood type.
Which of the blood types in the ABO
system may safely be given to a
person with AB blood?
1. O or AB, only
2. A or B, only
3. B or AB, only
4. A, B, AB, or O
