Section 1 – Heart Physiology and Cardiovascular System
These are the questions for the labs from the course material. Please
answer the questions, but also for each answer choice, explain why the
choice is correct or incorrect. For example, if the answer is B, please
explain why B is correct and why choices A, C, and D, etc., are incorrect,
for each question.
Note: Some of these questions cannot be explained in this way and are
marked with “No explanation needed.” Also, the fill-in-the-blank questions
do not need to be explained.
For the images, label all parts, if they are unlabeled.
For the matching questions, explain all choices, even if they were not
used to answer one of the questions. This will give you extra practice with
the material, which will help with synthesis and retention.
In addition to the online course materials, you can use the following videos
and worksheets to help you explain some of your answers:

Carotid branches
Part 1
• Which chambers of the heart pump blood to the lungs in the following
model?
, • A Incorrect: Right atrium is not correct because it pumps
deoxygenated blood from the tricuspid valve into the right
ventricle.
• B Incorrect: Left atrium is not correct because the left atrium
pumps oxygenated blood into the left ventricle.
• C Correct: Right ventricle, the right ventricle pumps blood to
the lungs.
• D Incorrect: Left ventricle is not correct because it pumps
oxygenated blood to the entire body.
• Which option correctly identifies the aorta?
, • A Incorrect: This is the superior vena cavae.
• B Correct: The Aorta arises from the left ventricle of the heart.
• C Incorrect: This is the pulmonary trunk that arises from the
right ventricle.
• D Incorrect: This is the Inferior vena cavae.
• Which option correctly identifies the aortic valve?
, • A Incorrect: This is the left ventricle.
• B Incorrect: This is the right ventricle.
• C Correct: This is the aortic valve.
• D Incorrect: This is the pulmonary valve.
• Which choice correctly identifies the blood vessel that the arrows
point to?
