Which type of veins connect two primary capillary networks?
A) Portal veins
B) Venous sinuses
C) Venules
D) Vaso vasorum
Portal Veins
Veins that carry blood from various organs to the liver, allowing for detoxification and nutrient processing before returning to the heart.
Primary Capillary Networks
The initial network of capillaries where exchange of gases, nutrients, and wastes occurs between the blood and surrounding tissues.
Venous Sinuses
Large veins found in the brain and heart that collect deoxygenated blood to return it to the right atrium of the heart.

Final Answer :
A
Explanation :
Portal veins are the type of veins that connect two primary capillary networks, facilitating the transport of blood from one group of capillaries to another before it returns to the heart. This is seen in the hepatic portal system, where blood from the gastrointestinal tract is transported to the liver's capillary beds for processing before returning to the heart.
