Solutions to Exercises for Lesson 1

1.   Waste products are picked up by the capillaries and transported by the blood to the excretory organs that then eliminate them from the body.

2.  b

3.  c

4.  a

5.  d

6.  b

7.  d

8.  c

9.  d

10.  c  Note: This conclusion can be drawn from the fact than no other blood group mismatch will cause the blood to agglutinize.

11.   A universal donor's blood can be generally accepted, without adverse effect, by a person with any A-B-O blood type. If the blood transfused is type O Rh-positive and the recipient is an Rh-negative female, it can cause her blood to develop antibodies. These antibodies will fight the blood of an Rh-positive fetus she may carry during pregnancy. (para 1-10)
