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
Which activity is NOT a function of white blood cells
in response to an invasion of the body by
bacteria?
1. engulfing these bacteria
2. producing antibodies to act against this type of
bacteria
3. preparing for future invasions of this type of
bacteria
4. speeding transmissions of nerve impulses to
detect these bacteria
Which part of the human blood transports
hormones and nutrients?
1. plasma
2. platelets
3. red blood cells
4. white blood cells
The breaking apart of platelets in the blood
helps in the
1. synthesis of hemoglobin
2. formation of a clot
3. release of antibodies
4. deamination of amino acids
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.
Blood normally flows from the
capillaries directly into
1.small arteries
2.small veins
3. lymph vessels
4. heart atria
The movement of blood from the legs toward
the heart is hindered by gravity. The effect
of gravity is counteracted by
a. smooth muscle in the capillaries
b. cilia lining the blood vessels
c. valves in the veins
d. lymph nodes near major vessels
Which statement best describes arteries?
a. They have thick walls and transport blood
away from the heart.
b. They have thick walls and transport blood
toward the heart.
c. They have thin walls and transport blood
away from the heart.
d. They have thin walls and transport blood
toward the heart.
1. Identify the upper chambers of the
heart. Right and left atria
2. Identify the lower chambers of the
heart. Right and left ventricles
3. Identify the structures that separate the
upper and lower chambers. valves
4. Identify the wall that separates the right
and left side of the heart. septum
Identify structures B, D, E, F and H.
aorta
left
atrium
right
atrium
left
ventricle
right ventricle
When blood passes
through the heart
from the left atrium
(D) to the left
ventricle (E), it must
first pass through a
valve
Identify the part of the heart being
described.
1. Chamber that 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. Chamber that pumps out deoxygenated
blood. Right ventricle
5. Chamber that receives deoxygenated
blood. Right atrium
6. Prevents the backflow of blood between
atria and ventricles. Valves
7. Chamber that pumps out oxygenated
blood. Left ventricle
For blood to pass through the heart from
the left atrium to the left ventricle, it
must first pass through
a. an artery
b. a valve
c. a vein
d. a capillary
Blood in the right ventricle will be
pumped to the
a. brain
b. small intestine
c. kidneys
d. lungs
Blood in the left atrium will move to the
a. brain
b. Lungs
c. left ventricle
d. right ventricle
What is a major difference between red blood
cells and white blood cells?
1. Red blood cells contain hemoglobin, but white
blood cells do not.
2. Red blood cells can move, but white blood
cells cannot.
3. Red blood cells contain nuclei, but white blood
cells do not.
4. Red blood cells engulf foreign bacteria, but
white blood cells do not.
What component of blood is
important in healing wounds on the
skin?
1.red blood cells
2.urea
3.platelets
4.white blood cells
Where are red and white blood
cells made in the body?
1.in lymph nodes
2.in bone marrow
3.at the sinoatrial node
4.in the heart
What component of blood plays
a role in protection against
disease?
1.white blood cells
2.platelets
3.urea
4.red blood cells
Which blood component is a
liquid?
1.platelets
2.white blood cells
3.plasma
4.red blood cells
