ART I. K II.-. 



The arterial system consists of two separate divisions of circulations. The 

 pulmonary arterywith its branches forms the lesser or pulmonary circulation, 

 and the aorta with its branches forms the greater or systemic circulation. 



Blood vessels. Vasa vasorum are blood vessels which supply the larger 

 arteries. The blood circulates through the body to nourish the various parts. 

 The circulation of the blood was demonstrated by Harvey in 1628. All ves 



sels which carry 1>I 1 from the heart are arteries, and those which carry blood 



to the heaii are veins. The connecting link between the arteries and the veins 

 is the capillaries. Harvey was not able to sec these connecting links for they 

 are microscopic and the microscope was no1 invented until some years later. 



Harvey said the l>l I filtered through the tissues from the arteries to the veins, 



which is not very far wrong. Malpighi discovered the capillaries in 1661. 

 As a rule the arteries carry pure or oxygenized blood, and the veins carry 

 impure or non-oxygenized blood, but there are exceptions to this rule forthe 

 pulmonary artery carries impure blood and the pulmonary veins carry pure 

 blood. Perhaps the puresl Mood in the body is in the right renal vein. 

 When the blood enters the kidney it is as pure as when it left the left ventricle 

 of the heart and in the kidney it throws off more impurities than it takes 

 from the kidney. The left renal vein receives the spermatic vein in the male 

 and the ovarian vein in the female, SO it contains blood less pure than the
