These structures carry blood toward the heart.
What are veins?

These two deep veins drain the forearm. 
What are the radial and ulnar veins?
100
This is how the inferior vena cava compares to the superior vena cava in length.
What is longer?
100
This is the major vein of the hepatic portal circulation.
What is the hepatic portal vein?
100
These structures are nonfunctional and collapsed in a fetus, so they must be bypassed. 
What are fetal lungs?
200
Compared to arteries, veins have this kind of pressure.
What is low pressure?
200
This vein joins the basilic and cephalic veins in the elbow region and is commonly used for blood draws.
What is the median cubital vein?
200
These are the longest veins in the body.
What are the great saphenous veins?
200
After a meal, the hepatic portal vein directs nutrient-rich blood through this organ. 
What is the liver?
200
The umbilical vein carries blood from the mother to the fetus and is rich in these two things.
What are oxygen and nutrients?
300

Veins converge into these structures before entering the heart.

What are the superior and inferior vena cava?
300
This single vein drains the thorax and joins the superior vena cava just before the heart.
What is the azygos vein?
300
This is the origin of the great saphenous veins.
What is the dorsal venous arch?
300
These two veins merge to form the hepatic portal vein.
What are the splenic vein and the superior mesenteric vein?
300
The umbilical arteries and umbilical vein begin to unweave from the umbilical cord at this point.
What is the fetal umbilicus?
400

This is the general position of veins compared to arteries in regards to distance from the skin. 

What is superficial?

400
The subclavian vein drains blood from these areas.
What are the arm as well as the skin and muscles of the head?
400
The common iliac vein is formed by these two veins.
What are the external iliac vein and the internal iliac vein?
400
The splenic vein drains these three organs.
What are the spleen, pancreas, and left stomach?
400
This structure allows blood to bypass the fetal liver and enter the inferior vena cava.
What is the ductus venosus?
500
This organ illustrates the division of body areas served by the superior and inferior vena cava. 
What is the diaphragm?
500
The brachiocephalic veins receive blood from these three veins on each side.
What are the subclavian, vertebral, and internal jugular veins?
500
These are the veins that blood travels through from the posterior tibial veins to the inferior vena cava.
What are the popliteal vein, femoral vein, external iliac vein, and the common iliac vein?
500
The hepatic portal system is unusual because of its second capillary bed, which serves this purpose.
What is to deliver nutrients and toxins to the liver before entering systemic circulation?
500
The fetal inferior vena cava contains blood with this level of oxygenation.
What is moderate oxygenation?
