Write the answer to each of the following questions on your paper. When instructed to do so, show the answer to the people at your table. Without talking choose one answer and write it on the white wipe off board. Then flip the board upside down and wait for the teacher to say “the answer is…” At this time, hold your answer up so that the teacher can see the answer that was recorded. If you got the answer correct, record one point for your table and clean the board off for the next question. Remember: Don’t talk and give the answer away to another table!!
Which of the following is NOT a function of the cardiovascular system? A.Attacking disease-causing microorganisms B.Carrying oxygen, glucose, and other needed materials to cells C.Carrying waste products away from the cells D.Controlling many body processes by means of chemicals 2
And the answer is… D. Controlling many body processes by means of chemicals
Needed substances are carried to the body cells by A.Enzymes B.Blood C.Water D.Food 3
When blood flows into the right atrium from the body, it contains A.Little oxygen and a lot of carbon dioxide B.A lot of oxygen and little carbon dioxide C.A lot of both oxygen and carbon dioxide D.Little of either oxygen or carbon dioxide 6
And the answer is… A.Little oxygen and a lot of carbon dioxide
In which vessels are materials exchanged between the blood and the body cells? 7
Blood can flow freely through arteries because A.Arteries are lined with smooth muscle B.Arteries are lined with a layer of smooth epithelial cells C.Connective tissue pushes blood through the arteries D.Arteries have only one layer of cells 8
And the answer is… B. Arteries are lined with a layer of smooth epithelial cells
9 Which component of blood is 90 percent water?
What causes blood pressure? A.The force with which the ventricles contract B. The rate at which blood flows through the heart C.The speed at which oxygen is returned to blood in the lungs D.The strength of the muscles in the walls of the capillaries 10
And the answer is… A.The force with which the ventricles contract
Which component of blood carries oxygen to the body cells? 11
And the answer is… Red blood cells Which are made mostly of hemoglobin that binds chemically to oxygen.
12 What is the name of the part labeled with the # 5
Atherosclerosis is a condition in which A.Blood pressure is consistently higher than normal B.Muscles in artery walls lose their ability to contract C.Capillaries widen and release too much fluid D.Artery walls thicken as the result of a buildup of fatty materials 15
And the answer is… D. Artery walls thicken as the result of a buildup of fatty materials
16 The group of cells called the __________ regulates the rate at which the heart rate beats.
Why is atherosclerosis especially serious when it develops in the coronary arteries? A.It can then go on to affect the aorta. B.It can make red blood cells die. C.It can lead to a heart attack. D.It can limit the functioning of white blood cells. 17
And the answer is… C. It can lead to a heart attack.
18 A What is the name of the component labeled A?
Exercise is important for the cardiovascular health because it A.Increases blood pressure B.Strengthens heart muscles C.Makes the coronary arteries wider D.Reduces sodium in the blood 20
And the answer is… B. Strengthens heart muscles
21 To maintain cardiovascular health, foods high in fat should be avoided because A.They make the blood flow more slowly than normal. B.They decrease the force with which the ventricles can contract. C.They can lead to atherosclerosis. D.Fat in the diet harms red blood cells.
And the answer is… C. They can lead to atherosclerosis.
22 What structure prevents blood from flowing backward?
27 Hypertension is a condition in which A.Blood pressure is consistently lower than normal. B.Blood pressure is consistently higher than normal. C.Fatty deposits build up on artery walls. D.Some of the heart muscle dies.
And the answer is… B.Blood pressure is consistently higher than normal.
28 True or False As blood moves away from the heart, blood pressure increases.
And the answer is… False Blood pressure decreases
29 Blood pressure is highest as the ventricles contract. What is the blood pressure in large arteries when the ventricles contract?
What eventually happens to fluid that leaks from capillaries into the surrounding tissues? A.It becomes fatty tissue B.It replaces dead body cells C.It enters the lymphatic system D.It replaces dead red blood cells 37
And the answer is… C. It enters the lymphatic system
38 To where does the structure numbered 2 carry blood?
40 For which of the three patients is there enough blood in his or her blood type? A. Sonya Jackson B. Maria Nevarez C. James Patel D. There is enough blood for all of the patients in the type they need.
