Click Heartbeat sound and listen for the two parts of the heartbeat, nicknamed “lub” and “dub.” Observe the heart. In fact, the “lub” sound is caused by valves from the atria to the ventricles closing, and the “dub” sound is caused by the valves from the ventricles to the blood vessels closing. (Note: The recording is not in sync with the heart animation.)

Question 1
1.

Why do you need blood?

*Answer in a complete sentence*

Question 2
2.

What organ pushes blood through the body

Question 3
3.

How many chambers does the heart have?
(This answer should be a number, no words)

Question 4
4.

Turn on Show labels. What are the names of the chambers?
*spell them correctly*

Question 5
5.

Do you see tiny “doors” that open and close as blood is pumped through the heart? ______
These are heart valves. Heart valves control the flow of blood through the heart.

Question 6
6.

What causes heart beat sounds?

*Answer in a complete sentence*

Question 7
7.

Why do you think the left atrium and left ventricle are shown on the right side of the diagram?

*Must answer in complete sentences*

Activity A: Blood Flow

Get the Gizmo ready:
 Turn off: Show labels.
 Turn on: Show blood flow.
1. Observe: Blood in each chamber of the heart is represented by little balls. Click Play and observe the balls as they move through the heart and lungs.
2. Label: Click Pause and turn on Show labels.
Question 8
8.

Label the four chambers of the heart on the diagram. Then draw arrows to show the direction that blood flows through the heart.

Question 9
9.

Which order does the blood flow through the heart?

  1. Right Atrium
  2. Left Atrium
  3. Left Ventricle
  4. Right Ventricle
Analyze: Click Play. Observe the path of blood that leaves each ventricle.
Question 10
10.

Where does blood from the right ventricle go?

Question 11
11.

Where does blood from the left ventricle go? Don't put the Aorta as your answer. Where does the Aorta take the blood? (don't list the organs, just use a general term)

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.
Question 12
12.

What is the concentration of oxygen in this sample?

Question 13
13.

What is the concentration of carbon dioxide in this sample?

Collect data: Now collect a blood sample from the left atrium.
Question 14
14.

What is the concentration of oxygen in this sample?

Question 15
15.

What is the concentration of carbon dioxide in this sample?

Question 16
16.

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?

*Answer in complete sentences*

Activity B: Blood Circulation
How is blood carried to the different parts of the body?

Get the Gizmo ready:
 Check that Show labels is on.
 Turn on Show blood flow.
Question 17
17.

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

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.
Use the syringe to take blood samples from several different veins and arteries.
Question 18
18.

Which type of blood vessel usually carries oxygen rich blood?

Question 19
19.

Which type of blood vessel usually carries oxygen-poor blood?

Question 20
20.

In which type of blood vessel is oxygen released into body cells?

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.
Question 21
21.

How is the blood from the pulmonary arteries different from the blood in other arteries?

Question 22
22.

How is the blood in the pulmonary veins different from blood in other veins?

Question 23
23.

How is the circulatory system similar to a road-and-highway system?

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)
Question 24
24.

Match the blood cell with the correct description.

What's in your blood?

Take a blood sample from any blood vessel using the syringe.

Click the camera icon to take a Gizmo snapshot, and then paste your snapshot into the show your work box.
Question 25
25.

Click the camera icon to take a Gizmo snapshot, and then paste your snapshot into the show your work box.

Find and label a red blood cell, platelet, and white blood cell in your blood sample.

Question 26
26.

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?

Write it in the table in the show your work box.

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

*Think about sugar concentrations in the blood*
Question 27
27.

Where does sugar enter the blood?

(find an organ with high sugar levels)

Question 28
28.

How can you tell where sugar enters the blood?

Question 29
29.

Where is sugar removed from the blood?

Question 30
30.

How can you tell?

Investigate: Take blood samples to determine where urea enters the blood and is removed. (Urea is the main component of Urine)
Question 31
31.

Where does urea enter the blood? (which organ)
*This will be where the urea levels are the highest*

Question 32
32.

Where is urea removed from the blood? (which organ)
