A CONTRAST. 
Heart— Artery. 
1. The soluble and nutritious 
portion of the food passes from 
the digestive tube into the lac- 
teals, and through the mesen- 
teric glands and thoracic duct 
into the left subclavian vein. 
2. It is a large ARTERY, which 
takes the blood to the lungs. 
3. To this artery a HEART* is 
prefixed. 
4. Into the heart, large VE- 
NOUS roots go — the cavse. 
5. Out of the heart comes an 
ARTERY — the pulmonary or car- 
dio-pulmonic. 
6. The reverse or contrary of 
the ARTERY is the VEIN. 
Spleen — Vein. 
1. The soluble and nutritious 
portion of the food, as well as 
the drink, passes from the di- 
gestive tube into the intestinal 
capillaries, and through the me- 
senteric veins into the middle of 
the trunk of that Great Vein, 
whose roots are in the spleen, 
and whose branches are in the 
liver. 
2. It is a large VEIN, which 
takes the blood to the liver. 
3. To this vein the SPLEEN 
is prefixed. 
4. Into the spleen, small 
ARTERIAL branches go — the 
branches of the splenic artery. 
5. Out of the spleen comes a 
VEIN— the splenic or spleno- 
hepatic. 
6. The reverse or contrary of 
the HEART is the SPLEEN. 
Diametrically different anatomical causes produce diametrically 
different physiological effects. 
7. The bloodvessel going to 
the lungs, consisting of a HEART 
and an ARTERY, produces a con- 
stant and rapid motion of the 
blood through the capillaries of 
the lungs. 
7. The bloodvessel going to 
the liver, consisting of the 
SPLEEN and a VEIN, produces 
ari intermittent and slow motion 
of the blood through the capil- 
laries of the liver.
