Short Answer
|
| |
30. |
Use
the diagram of the heart (Figure 1) to answer the questions that
follow.
Figure 1
a.
Identify the number(s) of the blood vessel(s) that return blood to the
heart from the body.
b Identify the ventricle that contains deoxygenated
blood.
c Identify the heart valves that produce the lubb
sound when closing.
d Identify the blood vessel(s) that brings oxygenated
blood to the heart from the lungs.
|
| |
31. |
Arrange the following blood vessels in the correct order as blood
leaves the left ventricle of the heart: capillary, aorta, vein, arteriole,
artery, and venule.
|
| |
32. |

are the common symptoms of a heart attack?

a. Why is protein found only in the glomerulus?
b Explain why amino acids do not appear in the
loop of Henle or in the collecting duct.
c What evidence suggests that toxic materials are
more concentrated as they are excreted?

Give
the sequence of structures and tubes through which a molecule of water
would pass as it is filtered out of the glomerulus until it enters the
urethra.
