Homework #11

1. You have just worked out at the gym and
accumulated lots of metabolic wastes in your
blood.
Physiologically, these wastes first need to
be processed by your liver to detoxify them before
they can be excreted into your urine via the
kidney.
What is the shortest route through the
blood circulation the wastes can take from the
time they are picked up in your muscles (for
example, a leg muscle), allowing them to be
processed by the liver, and finally excreted
through the kidney?
Choose the shortest route that includes all
necessary organs. (0.5 pt)

2. Starting with the right ventricle (1), place all the listed structures in the correct
order in which blood passes through them.
(Structures: aorta, aortic semilunar
valve, left atrium, left ventricle, lung capillaries, mitral valve, pulmonary arteries,
pulmonary semilunar valve, pulmonary trunk, pulmonary veins, right atrium, right
ventricle, superior and inferior vena cava, systemic capillaries, tricuspid valve.)

3. The figure to the right depicts the electrical conducting system
of the heart.
In the figure, what structure of the electrical
conducting system corresponds to each letter?
Choose from the
list of structures below.
(0.5 pt)
Atrioventricular node
Interventricular septum
Bundle branches
Papillary muscle
Bundle of His
Purkinje fibers
Chordae tendineae
Sinoatrial node
Gap junction
4. Indicate the primary tissue type of each of the following
structures of the heart’s electrical conducting system.
(Choices:
Connective tissue, epithelial tissue, muscle tissue, nervous
tissue.) (0.3 pt)
Atrioventricular node
Purkinje fibers
Bundle branches
Sinoatrial node
5. To diagnose cardiovascular problems, a technique known as angiography can be
performed to visualize blood flow in the affected area.
A catheter is inserted
through the wall of a blood vessel and then threaded into the area of interest, where
an x-ray contrast agent is released.
The contrast agent is carried along with the
flow of blood and is visible on the x-ray for a short distance (e.g. an inch) from the
point of release.
To visualize blood flow through the coronary arteries, what is an
appropriate site to insert the catheter?
Keep in mind that catheters are much wider
than capillaries!
(Choose all that apply.) (0.5 pt)
a. Artery of thigh
b. Vein of thigh
c. Pulmonary artery
6. Compare and contrast the lymphatic system and the immune system.
For each of
the features listed below, decide whether it is true of a healthy lymphatic system,
healthy immune system, both, or neither.
