Heart and
blood flow Human
Physiology and Anatomy 231 Summer Learning Plan |
Overview
|
The heart’s job is to move
blood through the body. How does it do this effectively, where does the blood
go, and how can you tell if the heart is working properly? |

Tuesday Class
– Heart Function
|
_____1. |
Write notes on the basic anatomy of the
heart. (Figure 20.7) |
|
_____2. |
Discuss the
pacemaker action potential and how it causes the autorhythmic function of the
heart. (Figure 20.15, pp.691-695) |
|
_____3. |
Map the conduction system in the heart
and discuss how it transmits and regulates action potentials. (Figure 20.13) |
|
_____4. |
Discuss how the sympathetic nervous
system and the parasympathetic nervous system affect heart contraction. (pp.
706-708) |
|
_____2. |
WATCH and RECORD how the EKG trace
corresponds to heart contraction. |
|
_____3. |
INTERPRET an EKG trace, identifying which peak represents which event |

|
_____4. |
WRITE a complete answer to the following question. Back
up your answer with logical arguments based on physiological concepts. Dr. Bob did his first open-heart surgery! He replaced the
aortic semilunar valve in a man who had aortic regurgitation (a leaky valve
that wouldn’t close properly). Before his surgery, the man suffered from low
blood pressure even though his heart rate was very fast. He looked pale all the time, was sweaty and
anxious, and passed out a lot. So surgery was scheduled to replace his leaky
valve with a valve that didn’t leak. How did this man’s valve problems cause his signs and
symptoms? Dr. Bob put the new valve in
upside down. Will this matter? Why or why not? |
