Study Guide for Anatomy and Physiology Test Unit 8, Circulatory system and lungs!
Thacker 4/2017
Test covering Circulatory System and Respiratory/Lungs will be on
What will I be tested on??? Well, I suggest you look at your notes and ask yourself questions about the content…not just
the simple questions, you know those, but questions where you need to describe, explain, connect, & compare! Sit with
a friend and ask each other about the content and have conversations about it, not just single word answers….this is real
learning! But, here are some helpful statements that can help you generate conversations:

We first started the unit by comparing the circulatory systems of different organisms. What is the general
theme about type of system and higher functioning organisms?
What constitutes the circulatory system/
Describe the structures of the heart and their locations. Be able to label the structures of the heart on an
illustration. What are the functions of these structures.
Can you describe the pathway of blood through the heart..remember to use academic directional vocabulary!
There are three types of blood vessels, what are their structures and how do those structures contribute to their
function?
What are the basic constituents of blood? (we will go into this more during the lymphatic system)
Basically what are the functions of the heart??
Be able to name, locate and describe the functions of the heart valves. (see heartbeat activity for more)
Describe the heart skeleton and functions as well as cardiac muscle.
How can you calculate your heart rate? What factors increase or decrease heart rate?
What is an independent/dependent variable? Can you identify which is which in an example?
What is Cardiac Index? How is it measured? What values do you need to know to calculate this? Stroke vol?
Know the correlation of animal size, longevity and heartrate.

Understand the electrical impulse pathway of the heart through the nodes and how this triggers depolarization,
and repolarization.
Know which node actually initiates the beat and rhythm.
Be able to describe events happening when given an example ECG graph.
Describe what generates the heart sound.
Describe what factors affect blood pressure.
Understand how baroreceptors and chemoreceptors maintain the heart homeostasis.
What happens to your heart as you age?

How do you define blood pressure? How do you take blood pressure? What is the instrument called?
What does systolic and diastolic mean?
Be able to identify major veins and arteries on an illustration with directional terms.
How is blood flow different when you exercise compared to at rest?
What kinds of things can affect blood pressure and it what way?
What is the term for high and low blood pressure? What is considered normal?
Be able to label the major arteries and veins from and to the heart.

What is the driving need for respiration?
What are the principal organs of the respiratory system and how are they divided into the two divisions?
Describe the lungs and the structures leading into and within the lungs.
What is different about the left and right lungs?
Describe the tissues that surround the lungs and their functions.
Name the three types of cells of the Alveolus and their functions
What function does the respiratory membrane serve? Why is this important?
Describe how surface tension is critical to the exchange of gasses in the Alveolar.
Pressure plays a huge role in breathing. Describe what happens to the flow of air under different pressures.
Relate what happens to lungs to Boyle’s Law, Charles’ Law?
List the conditions that influence airway resistance.
What are the major muscles are used in respiration?
What parts of the Brain (nervous system) control voluntary and involuntary breathing?
Describe 2 problems that can occur?
Describe the factors that affect Gas Exchange in the alveolar
What is Dalton’s Law?
Be able to label the differences in pressures at various locations for the image of the heart and lung on page

18. Why does CO interfere with O2 carrying capacity?
19. What is VO2max and how can this be increased? Is it good to have a high VO2max?(additional ppt of this topic
