Circulatory System Gizmo Answers

Posted on

The Circulatory System is one of the science materials you can find on Gizmo. The material shows the heart and blood vessels which make up the circulatory system. It is known that the circulatory system works to pump blood from the heart to the lungs to get oxygen.

Once learning about Circulatory System, you can take the Circulatory System test on Gizmo. Of course, you need to answer all the questions correctly to get a high score. Do you need the Circulatory System answers? If you accidentally look for the answers to the Circulatory System, you can see them in our post below.

Circulatory System Gizmo Answers

There are four sections on Circulatory System test, including Warming Up, Activity A, Activity B and Extension. To show you the Circulatory System Gizmo Answers, we will show you the answers to Circulatory System for Activity A, B and Extension that we got from StuDocu.  We show the correct answers highlighted in bold font.

Here are they:

Warming Up

Circulatory System Gizmo Answers Gizmo   Warm-up

  1. How   many   chambers   does   the   heart   have?  4
  2. What are the names of the chambers? Right atrium, left atrium, right atrium and left ventricle
  3. Do you see tiny ‘doors’ that open and close as blood is pumped through the heart? Yes?
  4. What do you think causes heartbeat sounds? I think the blood being pumped through the heat makes that sound.
  5. Challenge: Why do you think the left atrium and left ventricle are shown on the right side of the diagram? It’s like that because of the anatomical position.

Activity A – Blood Flow

Question: How does blood flow through the heart?

Circulatory System Gizmo Answers- Activity A – Blood Flow

  1. Observe: Blood   in   each   chamber   of   the   heart   is   represented   by little balls. You may need to click ‘Play’ and   observe   the   balls   when   they   move   through the   heart   and   lungs.
  1. Label:   Click ‘Pause’ and   turn   on    Show   labels.   Label   the   four   chambers   of   the   heart   on   the   diagram.   Then, draw   arrows   to   show   the direction   that   blood   flows   through   the   heart.

Starting   at   the   right   atrium, in   what   order   does   blood   flow   through   the four   chambers?

Right Atrium Right Ventricle Left Atrium Left Ventricle
  1. Analyze: Click ‘Play’. Observe the path of blood that leaves each ventricle.

A. Where does blood from the right ventricle go?  It goes into the lungs
B. Where does blood from the left ventricle go? It goes into the head, arms, liver, kidneys, intestines and legs.

  1. Collect   data:   Use   the    syringe    to   collect   a   blood   sample   from   the   right   ventricle (on   the   left   side   of   the   heart diagram).   Look   at   the    Data   from   blood   sample    numbers.

A. What is the concentration of oxygen in this sample? 36.3
B. What is the concentration of carbon dioxide in this sample? 47.5

  1. Collect   data:   Now   collect   a   blood   sample   from   the   left   atrium.

A. What is the concentration of oxygen in this sample? 93.6
B. What is the concentration of carbon dioxide in this sample? 38.7

  1. Draw Conclusions: Between the right ventricle and the left atrium, blood goes through the lungs. Based on the data you have collected, what happens in the lungs?

The lungs add oxygen and remove carbon dioxide

Activity B – Blood Circulation

Question: How is blood carried to different parts of the body?

  1. Observe:   Click    Play    and   watch   the   blood   after   it   leaves   the   left   ventricle.   What   are   some   places   that   blood goes   after   leaving   the   heart?

The head, arms, liver, kidneys, intestines and legs

  1. Compare:   The   Gizmo   shows   three   types   of   blood   vessels.    Arteries    carry   blood   away   from   the   heart,  capillaries    are   small   vessels   that   carry   blood   to   body   cells,   and    veins    carry   blood   back   to   the   heart.   Locate  examples   of   arteries,   veins,   and   capillaries.

You can use   the    syringe    to   take   blood   samples   from   several   different   veins   and   arteries

A. Which type of blood vessel usually carries oxygen-rich blood? Arteries
B. Which type of blood vessel usually carries oxygen-poor blood? Veins
C. In which type of blood vessel is oxygen released into body cells? Capillaries

  1. Challenge:   The    pulmonary   arteries     carry   blood   from   the   right   ventricle   to   the   right   and   left   lungs.   The  pulmonary   veins     carry   blood   from   the   lungs   back   to   the   left   atrium.   Locate   these   blood   vessels,   and   use  the    syringe    to   take   a   blood   sample   from   each.

A. How is the blood in the pulmonary arteries different from blood in other arteries? The blood has less oxygen in it.
B. How is the blood in the pulmonary veins different from blood in other veins? The blood has oxygen in it.

  1. Extend   your   thinking:   How   is   the   circulatory   system   similar   to   a   road-and-highway   system? They   both   transport   to   get   a   final   destination.

Extension – What’s in Your Blood?

Circulatory System Gizmo Answers- Extension – What’s in Your Blood

Question: What is inside blood?

  1. Observe: Look   at   the    Microscopic   view   of   blood   samples .  Sketch   what   you   see   in   the   space   at   right.   (If   you   like,   you   could   also   click   the    camera    icon   to   take   a   Gizmo  snapshot,   and   then   paste   your   snapshot   into   a   blank  word-processing   document.)

Find   and   label   the   following   objects   in   your   sketch:

  • Red   blood   cells (small, round   cells   that   carry   oxygen)
  • White   blood   cells (large, irregular   cells   that   fight   disease)
  • Platelets (tiny   fragments   that   help   to   stop   bleeding   when   you  are   cut)
  1. Collect   data:   Blood   carries   many   vital   substances.   Four   of   these   are   listed   above   the    Microscopic   view.  Oxygen     and   sugar   are   needed   by   all   body   cells.   Carbon   dioxide   and   urea     are   waste   products.

What   are   the  concentrations   of   each   substance   in   this   sample?
Oxygen: 93.3
Carbon Dioxide: 39.6
Sugar: 118.5
Urea: 13.8

  1. Investigate:   Take   samples   of   blood   from   all   over   the   body.   Try   to   determine   where   sugar   enters   the   blood and   where   it   is   removed.

A. Where does sugar enter the blood? Through the liver
B. How can you tell where sugar enters the blood? The blood sugar was high there
C. Where is sugar removed from the blood? Through the left kidney
D. How can you tell? The blood sugar is low there

  1. Investigate:   Take   samples   of   blood   from   all   over   the   body.   Try   to   determine   where   sugar   enters   the   blood  and   where   it   is   removed.

A. Where does urea enter the blood? The liver
B. Where is urea removed from the blood? The Kidney
