Short Answer
18. You have had an accident and need a blood transfusion. You have type B blood. Your mother has type O. Can
she give her blood to you?
Yes. Type B blood has only antibodies against type A blood so you can receive O or B
blood if the Rh factors are compatible.
19. Explain the blood clotting process.
Platelets stick to a wound and release chemicals, then clotting factors carry out
chemical reactions that cause fibrin to form a sticky net. This net traps escaping blood
cells and plasma and forms a clot. After the clot hardens, skin cells begin repairing the
area.
20. Why is the pulmonary vein the only oxygen-rich vein in your body?
because it brings blood to the heart from the lungs, where it picks up oxygen
21. What is the purpose of pulmonary circulation?
to take blood to the lungs to release carbon dioxide and pick up oxygen for respiration
22. Type AB blood can receive blood from all other blood types but can donate only to other AB blood types.
Why?
All other blood types have antibodies that will clump type AB blood. AB blood has no
antibodies, so it will not clump any donated blood.
23. Name the parts of blood and describe their functions.
Blood consists of plasma, the liquid part of blood that carries nutrients and oxygen,
red blood cells that carry oxygen and carbon dioxide, white blood cells that fight
viruses and bacteria, and platelets, which are cell fragments that help to clot blood.
24. Why would physicians treat leukemia by transplanting bone marrow from a healthy person to the sick person?
White blood cells are produced in bone marrow. The bone marrow of the leukemia
patient produces immature white blood cells, but new marrow from a transplant may
produce normal, mature ones.
25. What are the four functions of blood?
Blood carries oxygen from the lungs to body cells and carries carbon dioxide back to
the lungs; blood carries waste products from cells to the kidneys; blood transports
nutrients to body cells; blood contains cells and molecules that fight infections and
heal wounds.
26. Describe systolic and diastolic blood pressure.
Systolic pressure is a measure of the pressure caused when ventricles contract and
blood is pushed out of the heart. It is indicated by the first of two numbers used to
express blood pressure. Diastolic pressure is a measure of the pressure that occurs as
the ventricles fill with blood just before they contract again. It is indicated by the
second of two numbers used to express blood pressure.
27. Why are there no valves in arteries?
Blood in the arteries is pushed along by the pumping of the heart and the smooth
muscles of the artery walls.
28. What are some steps you can take to prevent cardiovascular disease?
regular checkups, a healthful diet, exercise, maintaining a healthy weight, reducing
stress, not smoking
29. Why are there 5 million red blood cells but only 10,000 white blood cells in your body?
You need red blood cells every minute to carry oxygen and carbon dioxide. White
blood cells are needed only when your body is attacked by pathogens.
30. Why are the walls of capillaries only one cell thick?
Oxygen and nutrients must diffuse to body cells through the capillary walls, and carbon dioxide
and wastes diffuse from body cells to the capillaries in the same way
31. Place in order the path that blood takes in your body, beginning with blood entering the heart from the body
tissues:
___2___ right atrium contracts and blood enters right ventricle
__4____ blood leaves right ventricle in pulmonary arteries
___7___ left atrium contracts and blood enters left ventricle
__1____ blood enters right atrium in veins from body tissue
___6___ oxygen-rich blood returns to left atrium
___3___ right ventricle contracts
___9___ blood leaves heart in arteries to body tissues
__5____ blood in pulmonary arteries exchanges carbon dioxide for oxygen
___8___ left ventricle contracts
