A photograph of a slide of human blood taken from a healthy individual is shown below. Use this photograph to answer questions 1 and 2 which follow.
1. Which statement best describes the change that would be observed if the slide contained blood from an individual with anemia?
(1.) Cell type A would be larger in size and darker in appearance.
(2.) Cell type B would be larger in size and
greater in number. (3.) Cell type A would be fewer in number and larger in size.
(4.) Cell type B would be fewer in number and lighter in appearance.
2. What kind of blood cell is the cell labeled B in the diagram? (1.) red blood cell (2.) platelet (3.) phagocyte (4.) lymphocyte
3. Structures specialized for returning blood to the heart are known as (1.) capillaries (2.) arteries (3.) veins (4.) bronchioles
4. Which transport structures have specialized regions for filtering out bacteria and dead cells? (1.) arteries (2.) veins (3.) capillaries (4.) lymph vessels
5. The diagram below shows a sequence of events that occurs in humans. Which information belongs in box A?
(1.) increase in breathing rate (2.) formation of a clot (3.) formation of urea (4.) decrease in body temperature
6. A pulse can be detected most easily in (1.) a vein (2.) an artery (3.) a capillary (4.) a lymph vessel
|
7. The diagram represents the human lymphatic system. A major function of the structures labeled X is (1.) pump lymph in the proper direction (2.) remove undigested food from the blood (3.) filter bacteria and dead cells from the lymph (4.) transport glucose throughout the body

8. An insufficient amount of hemoglobin is most closely associated with the disorder known as (1.) coronary thrombosis (2.) anemia (3.) leukemia (4.) stroke
9. Which part of the blood is correctly paired with its function? (1.) platelets - produce antibodies (2.) white blood cells - carry oxygen (3.) red blood cells - fight infection (4.) plasma - transports wastes and hormones
10. Which organic compounds are needed for the synthesis of the plasma membrane, contain a large amount of stored energy, and have been linked to cardiovascular diseases? (1.) complex carbohydrates (2.) saturated fats (3.) polyunsaturated fats (4.) simple sugars
11. Which statement accurately describes human capillaries? (1.) They have walls one cell in thickness. (2.) They have valves to prevent backflow of blood. (3.) They contract to assist blood flow. (4.) They filter bacteria out of the blood.
12. Dissolved nutrients, wastes, and oxygen are exchanged between the blood and intercellular fluid through the walls of (1.) arteries (2.) veins (3.) capillaries (4.) ventricles
13. The exchange of materials between the blood and the intercellular fluid (ICF) occurs readily through structures known as (1.) arteries (2.) veins (3.) capillaries (4.) villi
14. Which condition results from brain cell damage due to blocked or burst blood vessels and is characterized by impaired speech or motor patterns? (1.) diabetes (2.) stroke (3.) meningitis (4.) leukemia
15. Which condition is characterized by a narrowing of the coronary arteries causing an inadequate supply of oxygen to the heart muscle? (1.) meningitis (2.) angina pectoris (3.) emphysema (4.) leukemia
** In the first two groups of questions choices may be used once, more than once, or not at all.
Identify each of the following statements as being more closely associated with either arteries (A), veins (V), or capillaries (C). Place an A,V, or C in the blank before each statement as is appropriate.
_____ 1. Contain valves to prevent the backflow of blood.
_____ 2. Microscopic blood vessels.
_____ 3. Exchange of materials occurs from these vessels.
_____ 4. Vessels in which the pulse is felt.
_____ 5. Usually carry the most oxygenated blood.
_____ 6. Usually carry the most deoxygenated blood.
_____ 7. The most muscular blood vessels.
_____ 8. These blood vessels carry blood from the heart.
_____ 9. These vessels return blood to the heart.
Indicate whether the following statement is most closely associated with a red blood cell (RBC), white blood cell (WBC), or platelet (P).
_____ 1. These aid in blood clotting.
_____ 2. The chief function of these cells is to carry oxygen.
_____ 3. The chief function of these cells is to fight disease.
_____ 4. These are the largest blood cells and possess a nucleus.
_____ 5. Phagocytes and lymphocytes are examples of these kinds of cells.
_____ 6. These blood cells are biconcave disk shaped.
_____ 7. These are the most numerous blood cells.
_____ 8. These cells contain hemoglobin.
_____ 9. These are the smallest blood cells or cell fragments.
Correctly complete the following statements. Again, answers may be used more than once.
1. White blood cells which form antibodies are called _______________.
2. White blood cells which engulf and eat bacteria are called _______________.
3. Foreign proteins which invade the body causing an immune response are called _______________.
4. Substances formed by certain white blood cells to destroy foreign invaders are called _______________.
5. ICF becomes _______________ once it returns to vessels which return it to the veins.
6. The liquid portion of the blood which contains dissolved food, wastes, and hormones is called _______________.
7. A person with a bacterial infection would likely have a _________ than normal number of white blood cells.
