Click Play. Observe the path of blood that leaves each ventricle. Where does blood from the left ventricle go?
A. lungs
B. right atrium
C. left atrium
D. aorta
Why is the blood in the right ventricle low in oxygen?
A. Blood is coming from the lungs where oxygen diffuses into the blood
B. Blood is coming from the body where oxygen is used by tissues
Why is the blood in the left ventricle high in oxygen?
A. Blood is coming from the lungs where oxygen diffuses into the blood
B. Blood is coming from the body where oxygen is used by tissues
The Gizmo shows three types of blood vessels. Arteries (red) carry blood away from the heart and veins (blue) carry blood back to the heart. Locate examples of arteries and veins. Use the syringe to take blood samples from several different veins and arteries. Which type of blood vessel usually carries oxygen-rich blood?
A. Veins
B. Arteries
C. Both arteries and veins
D. Neither arteries and veins
