 causing the blood to clot. 



II. Blood is necessary for the body because (6) it acts as a medium 

 of exchange between the body cells and the source of their food supply ; 

 (7) it contains regulative substances called vitamins ; (8) it acts as a 

 carrier for the chemical activators called hormones ; (9) only through 

 the blood is oxygen carried to the cells and carbon dioxide carried 

 away; (10) it carries waste materials away from the cells.

 (28) are masses of tiny air sacs, which are thin walled and covered with 

 capillaries; (29) are made larger or smaller during the process of 

 breathing; (30) take in oxygen and give off water, carbon dioxide, 

 some organic wastes, and heat. 



VII. Respiration (31) is a process by which oxygen reaches the 

 body cells and carbon dioxide is removed from them; (32) is the 

 same as expiration and inspiration ; (33) takes place in body cells ; 

 (34) and breathing mean the same thing; (35) is raising and lower-
